 # Changelog
 
+## v4.5.0 - 2021-08-01
+
+**Important notes**
+
+A **BREAKING CHANGE** is introduced for JWT middleware users.
+The JWT library used for the JWT middleware had to be changed from [github.com/dgrijalva/jwt-go](https://github.com/dgrijalva/jwt-go) to
+[github.com/golang-jwt/jwt](https://github.com/golang-jwt/jwt) due former library being unmaintained and affected by security
+issues.
+The [github.com/golang-jwt/jwt](https://github.com/golang-jwt/jwt) project is a drop-in replacement, but supports only the latest 2 Go versions.
+So for JWT middleware users Go 1.15+ is required. For detailed information please read [#1940](https://github.com/labstack/echo/discussions/)
+
+To change the library imports in all .go files in your project replace all occurrences of `dgrijalva/jwt-go` with `golang-jwt/jwt`.
+
+For Linux CLI you can use:
+```bash
+find -type f -name "*.go" -exec sed -i "s/dgrijalva\/jwt-go/golang-jwt\/jwt/g" {} \;
+go mod tidy
+```
+
+**Fixes**
+
+* Change JWT library to `github.com/golang-jwt/jwt` [#1946](https://github.com/labstack/echo/pull/1946)
+
 ## v4.4.0 - 2021-07-12
 
 **Fixes**

Subject: [PATCH 004/371] Ignore case of auth scheme in request header

Some clients send an authorization header containing the "bearer"
keyword in lower case. This led to echo responding with "missing or
malformed jwt".

Request.BasicAuth (net/http) ignores the basic auth scheme's case since
a while: https://go-review.googlesource.com/c/go/+/111516/

+/**
+By: https://github.com/tmshn (See: https://github.com/labstack/echo/pull/1478 , https://github.com/labstack/echox/pull/134 )
+Source: https://echo.labstack.com/guide/ip-address/
+
+IP address plays fundamental role in HTTP; it's used for access control, auditing, geo-based access analysis and more.
+Echo provides handy method [`Context#RealIP()`](https://godoc.org/github.com/labstack/echo#Context) for that.
+
+However, it is not trivial to retrieve the _real_ IP address from requests especially when you put L7 proxies before the application.
+In such situation, _real_ IP needs to be relayed on HTTP layer from proxies to your app, but you must not trust HTTP headers unconditionally.
+Otherwise, you might give someone a chance of deceiving you. **A security risk!**
+
+To retrieve IP address reliably/securely, you must let your application be aware of the entire architecture of your infrastructure.
+In Echo, this can be done by configuring `Echo#IPExtractor` appropriately.
+This guides show you why and how.
+
+> Note: if you dont' set `Echo#IPExtractor` explicitly, Echo fallback to legacy behavior, which is not a good choice.
+
+Let's start from two questions to know the right direction:
+
+1. Do you put any HTTP (L7) proxy in front of the application?
+    - It includes both cloud solutions (such as AWS ALB or GCP HTTP LB) and OSS ones (such as Nginx, Envoy or Istio ingress gateway).
+2. If yes, what HTTP header do your proxies use to pass client IP to the application?
+
+## Case 1. With no proxy
+
+If you put no proxy (e.g.: directory facing to the internet), all you need to (and have to) see is IP address from network layer.
+Any HTTP header is untrustable because the clients have full control what headers to be set.
+
+In this case, use `echo.ExtractIPDirect()`.
+
+```go
+e.IPExtractor = echo.ExtractIPDirect()
+```
+
+## Case 2. With proxies using `X-Forwarded-For` header
+
+[`X-Forwared-For` (XFF)](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Forwarded-For) is the popular header
+to relay clients' IP addresses.
+At each hop on the proxies, they append the request IP address at the end of the header.
+
+Following example diagram illustrates this behavior.
+
+```text
+┌──────────┐            ┌──────────┐            ┌──────────┐            ┌──────────┐
+│ "Origin" │───────────>│ Proxy 1  │───────────>│ Proxy 2  │───────────>│ Your app │

+```
+
+In this case, use **first _untrustable_ IP reading from right**. Never use first one reading from left, as it is
+configurable by client. Here "trustable" means "you are sure the IP address belongs to your infrastructre".
+In above example, if `b` and `c` are trustable, the IP address of the client is `a` for both cases, never be `x`.
+
+In Echo, use `ExtractIPFromXFFHeader(...TrustOption)`.
+
+```go
+e.IPExtractor = echo.ExtractIPFromXFFHeader()
+```
+
+By default, it trusts internal IP addresses (loopback, link-local unicast, private-use and unique local address
+from [RFC6890](https://tools.ietf.org/html/rfc6890), [RFC4291](https://tools.ietf.org/html/rfc4291) and
+[RFC4193](https://tools.ietf.org/html/rfc4193)).
+To control this behavior, use [`TrustOption`](https://godoc.org/github.com/labstack/echo#TrustOption)s.
+
+E.g.:
+
+```go
+e.IPExtractor = echo.ExtractIPFromXFFHeader(
+	TrustLinkLocal(false),
+	TrustIPRanges(lbIPRange),
+)
+```
+
+- Ref: https://godoc.org/github.com/labstack/echo#TrustOption
+
+## Case 3. With proxies using `X-Real-IP` header
+
+`X-Real-IP` is another HTTP header to relay clients' IP addresses, but it carries only one address unlike XFF.
+
+If your proxies set this header, use `ExtractIPFromRealIPHeader(...TrustOption)`.
+
+```go
+e.IPExtractor = echo.ExtractIPFromRealIPHeader()
+```
+
+Again, it trusts internal IP addresses by default (loopback, link-local unicast, private-use and unique local address
+from [RFC6890](https://tools.ietf.org/html/rfc6890), [RFC4291](https://tools.ietf.org/html/rfc4291) and
+[RFC4193](https://tools.ietf.org/html/rfc4193)).
+To control this behavior, use [`TrustOption`](https://godoc.org/github.com/labstack/echo#TrustOption)s.
+
+- Ref: https://godoc.org/github.com/labstack/echo#TrustOption
+
+> **Never forget** to configure the outermost proxy (i.e.; at the edge of your infrastructure) **not to pass through incoming headers**.
+> Otherwise there is a chance of fraud, as it is what clients can control.
+
+## About default behavior
+
+In default behavior, Echo sees all of first XFF header, X-Real-IP header and IP from network layer.
+
+As you might already notice, after reading this article, this is not good.
+Sole reason this is default is just backward compatibility.

Subject: [PATCH 078/371] Add logger middleware template variables:
 `${time_unix_milli}` and `${time_unix_micro}` (#2206)

This patch introduces two template variables `${time_unix_milli}` and
`${time_unix_micro}` into the logger middleware.
Currently, there is no way to interpolate that UNIX milli and micro
seconds timestamp in a log entry, and go 1.17 or later runtime supports
the utility functions `time#UnixMilli()` and `time#UnixMicro()`
so this patch adds them as well.

see also: https://github.com/golang/go/issues/44196

 # Changelog
 
+## v4.8.0 - 2022-08-10
+
+**Most notable things**
+
+You can now add any arbitrary HTTP method type as a route [#2237](https://github.com/labstack/echo/pull/2237)
+```go
+e.Add("COPY", "/*", func(c echo.Context) error 
+  return c.String(http.StatusOK, "OK COPY")
+})
+```
+
+You can add custom 404 handler for specific paths [#2217](https://github.com/labstack/echo/pull/2217)
+```go
+e.RouteNotFound("/*", func(c echo.Context) error { return c.NoContent(http.StatusNotFound) })
+
+g := e.Group("/images")
+g.RouteNotFound("/*", func(c echo.Context) error { return c.NoContent(http.StatusNotFound) })
+```
+
+**Enhancements**
+
+* Add new value binding methods (UnixTimeMilli,TextUnmarshaler,JSONUnmarshaler) to Valuebinder [#2127](https://github.com/labstack/echo/pull/2127)
+* Refactor: body_limit middleware unit test [#2145](https://github.com/labstack/echo/pull/2145)
+* Refactor: Timeout mw: rework how test waits for timeout. [#2187](https://github.com/labstack/echo/pull/2187)
+* BasicAuth middleware returns 500 InternalServerError on invalid base64 strings but should return 400 [#2191](https://github.com/labstack/echo/pull/2191)
+* Refactor: duplicated findStaticChild process at findChildWithLabel [#2176](https://github.com/labstack/echo/pull/2176)
+* Allow different param names in different methods with same path scheme [#2209](https://github.com/labstack/echo/pull/2209)
+* Add support for registering handlers for different 404 routes [#2217](https://github.com/labstack/echo/pull/2217)
+* Middlewares should use errors.As() instead of type assertion on HTTPError [#2227](https://github.com/labstack/echo/pull/2227)
+* Allow arbitrary HTTP method types to be added as routes [#2237](https://github.com/labstack/echo/pull/2237)
+

 ## Supported Go versions
 
+Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with older versions.
+
 As of version 4.0.0, Echo is available as a [Go module](https://github.com/golang/go/wiki/Modules).
 Therefore a Go version capable of understanding /vN suffixed imports is required:
 
-- 1.9.7+
-- 1.10.3+
-- 1.14+
 
 Any of these versions will allow you to import Echo as `github.com/labstack/echo/v4` which is the recommended
 way of using Echo going forward.

 # Changelog
 
+## v4.10.0 - 2022-xx-xx
+
+**Security**
+
+This minor version bumps minimum Go version to 1.17 (from 1.16) due `golang.org/x/` packages we depend on. There are 
+several vulnerabilities fixed in these libraries. 
+
+Echo still tries to support last 4 Go versions but there are occasions we can not guarantee this promise.
+
+
+
+
 ## v4.9.1 - 2022-10-12
 
 **Fixes**

Subject: [PATCH 112/371] Additional configuration options for RequestLogger
 and Logger middleware (#2341)

* Add `middleware.RequestLoggerConfig.HandleError` configuration option to handle error within middleware with global error handler thus setting response status code decided by error handler and not derived from error itself.
* Add `middleware.LoggerConfig.CustomTagFunc` so Logger middleware can add custom text to logged row.

 # Changelog
 
-## v4.10.0 - 2022-xx-xx
+## v4.10.0 - 2022-12-27
 
 **Security**
 
-This minor version bumps minimum Go version to 1.17 (from 1.16) due `golang.org/x/` packages we depend on. There are 
-several vulnerabilities fixed in these libraries. 
+* We are deprecating JWT middleware in this repository. Please use https://github.com/labstack/echo-jwt instead. 
 
-Echo still tries to support last 4 Go versions but there are occasions we can not guarantee this promise.
+  JWT middleware is moved to separate repository to allow us to bump/upgrade version of JWT implementation (`github.com/golang-jwt/jwt`) we are using
+which we can not do in Echo core because this would break backwards compatibility guarantees we try to maintain.
 
+* This minor version bumps minimum Go version to 1.17 (from 1.16) due `golang.org/x/` packages we depend on. There are
+  several vulnerabilities fixed in these libraries.

Subject: [PATCH 136/371] Fixes the concurrency issue of calling the `Next()`
 proxy target on RRB (#2409)

* Fixes the concurrency issue of calling the `Next()` proxy target on round robin balancer

- fixed concurrency issue in `AddTarget()`
- moved `rand.New()` to the random balancer initializer func.
- internal code reorganized eliminating unnecessary pointer redirection
- employing `sync.Mutex` instead of `RWMutex` which brings additional overhead of tracking readers and writers. No need for that since the guarded code has no long-running operations, hence no realistic congestion.
- added additional guards without which the code would otherwise panic (e.g., the case where a random value is calculation when targets list is empty)
- added descriptions for func return values, what to expect in which case.
- Improve code test coverage

Subject: [PATCH 148/371] gzip response only if it exceeds a minimal length
 (#2267)

* gzip response only if it exceeds a minimal length

If the response is too short, e.g. a few bytes, compressing the
response makes it even larger. The new parameter MinLength to the
GzipConfig struct allows to set a threshold (in bytes) as of which
response size the compression should be applied. If the response
is shorter, no compression will be applied.

+## Echo
 
-Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with
-older versions.
+High performance, extensible, minimalist Go web framework.
 
-As of version 4.0.0, Echo is available as a [Go module](https://github.com/golang/go/wiki/Modules).
-Therefore a Go version capable of understanding /vN suffixed imports is required:
+* [Official website](https://echo.labstack.com)
+* [Quick start](https://echo.labstack.com/docs/quick-start)
+* [Middlewares](https://echo.labstack.com/docs/category/middleware)
 
-Any of these versions will allow you to import Echo as `github.com/labstack/echo/v4` which is the recommended
-way of using Echo going forward.
+Help and questions: [Github Discussions](https://github.com/labstack/echo/discussions)
 
-For older versions, please use the latest v3 tag.

 # Changelog
 
+## v4.13.0 - 2024-12-04
+
+**BREAKING CHANGE** JWT Middleware Removed from Core use [labstack/echo-jwt](https://github.com/labstack/echo-jwt) instead
+
+The JWT middleware has been **removed from Echo core** due to another security vulnerability, [CVE-2024-51744](https://nvd.nist.gov/vuln/detail/CVE-2024-51744). For more details, refer to issue [#2699](https://github.com/labstack/echo/issues/2699). A drop-in replacement is available in the [labstack/echo-jwt](https://github.com/labstack/echo-jwt) repository.
+
+**Important**: Direct assignments like `token := c.Get("user").(*jwt.Token)` will now cause a panic due to an invalid cast. Update your code accordingly. Replace the current imports from `"github.com/golang-jwt/jwt"` in your handlers to the new middleware version using `"github.com/golang-jwt/jwt/v5"`.
+
+
+Background: 
+
+The version of `golang-jwt/jwt` (v3.2.2) previously used in Echo core has been in an unmaintained state for some time. This is not the first vulnerability affecting this library; earlier issues were addressed in [PR #1946](https://github.com/labstack/echo/pull/1946).
+JWT middleware was marked as deprecated in Echo core as of [v4.10.0](https://github.com/labstack/echo/releases/tag/v4.10.0) on 2022-12-27. If you did not notice that, consider leveraging tools like [Staticcheck](https://staticcheck.dev/) to catch such deprecations earlier in you dev/CI flow.  For bonus points - check out [gosec](https://github.com/securego/gosec).
+
+We sincerely apologize for any inconvenience caused by this change. While we strive to maintain backward compatibility within Echo core, recurring security issues with third-party dependencies have forced this decision.
+
+**Enhancements**
+
+* remove jwt middleware by @stevenwhitehead in https://github.com/labstack/echo/pull/2701
+* optimization: struct alignment by @behnambm in https://github.com/labstack/echo/pull/2636
+* bind: Maintain backwards compatibility for map[string]interface{} binding by @thesaltree in https://github.com/labstack/echo/pull/2656
+* Add Go 1.23 to CI by @aldas in https://github.com/labstack/echo/pull/2675
+* improve `MultipartForm` test by @martinyonatann in https://github.com/labstack/echo/pull/2682
+* `bind` : add support of multipart multi files by @martinyonatann in https://github.com/labstack/echo/pull/2684
+* Add TemplateRenderer struct to ease creating renderers for `html/template` and `text/template` packages. by @aldas in https://github.com/labstack/echo/pull/2690
+* Refactor TestBasicAuth to utilize table-driven test format by @ErikOlson in https://github.com/labstack/echo/pull/2688
+* Remove broken header by @aldas in https://github.com/labstack/echo/pull/2705
+* fix(bind body): content-length can be -1 by @phamvinhdat in https://github.com/labstack/echo/pull/2710
+* CORS middleware should compile allowOrigin regexp at creation by @aldas in https://github.com/labstack/echo/pull/2709
+* Shorten Github issue template and add test example by @aldas in https://github.com/labstack/echo/pull/2711

Subject: [PATCH 233/371] Use Go 1.25 in CI (#2810)

* Use Go 1.25 in CI

* Disable test: in Go 1.24 and earlier http.NoBody would result ContentLength=-1 but as of Go 1.25 http.NoBody would result ContentLength=0 I am too lazy to bother documenting this as 2 version specific tests.

Subject: [PATCH 234/371] Fix IP extraction fallback and improve Response.Flush
 error messages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes two issues:

1. extractIP now handles RemoteAddr without port (#2757)
   - Previously returned empty string for addresses like "192.168.1.1"
   - Now validates with net.ParseIP and returns the IP directly
   - Maintains full backwards compatibility for existing behavior

2. Response.Flush uses modern error handling (#2789)
   - Replaces type assertion with http.NewResponseController
   - Provides descriptive panic message with ResponseWriter type info
   - Improves debugging experience when flushing is not supported

Both changes maintain full backwards compatibility while fixing edge cases.

Closes #2757
Closes #2789

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## About This Project
+
+Echo is a high performance, minimalist Go web framework. This is the main repository for Echo v4, which is available as a Go module at `github.com/labstack/echo/v4`.
+
+## Development Commands
+
+The project uses a Makefile for common development tasks:
+
+- `make check` - Run linting, vetting, and race condition tests (default target)
+- `make init` - Install required linting tools (golint, staticcheck)
+- `make lint` - Run staticcheck and golint
+- `make vet` - Run go vet
+- `make test` - Run short tests
+- `make race` - Run tests with race detector
+- `make benchmark` - Run benchmarks
+
+Example commands for development:
+```bash
+# Setup development environment
+make init
+
+# Run all checks (lint, vet, race)
+make check
+
+# Run specific tests
+go test ./middleware/...
+go test -race ./...
+
+# Run benchmarks
+make benchmark
+```
+
+## Code Architecture
+
+### Core Components
+
+**Echo Instance (`echo.go`)**
+- The `Echo` struct is the top-level framework instance
+- Contains router, middleware stacks, and server configuration
+- Not goroutine-safe for mutations after server start
+
+**Context (`context.go`)**
+- The `Context` interface represents HTTP request/response context
+- Provides methods for request/response handling, path parameters, data binding
+- Core abstraction for request processing
+
+**Router (`router.go`)**
+- Radix tree-based HTTP router with smart route prioritization
+- Supports static routes, parameterized routes (`/users/:id`), and wildcard routes (`/static/*`)
+- Each HTTP method has its own routing tree
+
+**Middleware (`middleware/`)**
+- Extensive middleware system with 50+ built-in middlewares
+- Middleware can be applied at Echo, Group, or individual route level
+- Common middleware: Logger, Recover, CORS, JWT, Rate Limiting, etc.
+
+### Key Patterns
+
+**Middleware Chain**
+- Pre-middleware runs before routing
+- Regular middleware runs after routing but before handlers
+- Middleware functions have signature `func(next echo.HandlerFunc) echo.HandlerFunc`
+
+**Route Groups**
+- Routes can be grouped with common prefixes and middleware
+- Groups support nested sub-groups
+- Defined in `group.go`
+
+**Data Binding**
+- Automatic binding of request data (JSON, XML, form) to Go structs
+- Implemented in `binder.go` with support for custom binders
+
+**Error Handling**
+- Centralized error handling via `HTTPErrorHandler`
+- Automatic panic recovery with stack traces
+
+## File Organization
+
+- Root directory: Core Echo functionality (echo.go, context.go, router.go, etc.)
+- `middleware/`: All built-in middleware implementations
+- `_test/`: Test fixtures and utilities
+- `_fixture/`: Test data files
+
+## Code Style
+
+- Go code uses tabs for indentation (per .editorconfig)
+- Follows standard Go conventions and formatting
+- Uses gofmt, golint, and staticcheck for code quality
+
+## Testing
+
+- Standard Go testing with `testing` package
+- Tests include unit tests, integration tests, and benchmarks
+- Race condition testing is required (`make race`)
+- Test files follow `*_test.go` naming convention

Subject: [PATCH 236/371] Fix DefaultBinder empty body handling for unknown
 ContentLength
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix issue where POST requests with empty bodies and ContentLength=-1
(unknown/chunked encoding) incorrectly fail with 415 Unsupported Media Type.

The DefaultBinder.BindBody method now properly detects truly empty bodies
when ContentLength=-1 by peeking at the first byte. If no content is found,
it returns early without error. If content exists, it reconstructs the body
to preserve the original data.

Fixes #2813

Subject: [PATCH 237/371] Revert Issue #2813 fix based on maintainer feedback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Revert the DefaultBinder empty body handling changes following
@aldas's concerns about:
- Body replacement potentially interfering with custom readers
- Lack of proper reproduction case for the original issue
- Potential over-engineering for an edge case

The "read one byte and reconstruct body" approach could interfere
with users who add custom readers with specific behavior.

Waiting for better reproduction case and less invasive solution.

Subject: [PATCH 238/371] Add comprehensive tests for IP extraction
 improvements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds tests for issue #2757 IP extraction edge cases where RemoteAddr
may not include a port. The enhanced extractIP function now properly
handles IPv4/IPv6 addresses without ports using net.ParseIP validation.

Test cases cover:
- IPv4 without port
- IPv6 without port
- IPv6 with port brackets
- Invalid IP format handling

Existing tests for issue #2789 response flush error handling are already
comprehensive and validate the improved error messages with ResponseWriter types.

Fixes #2757

- File output configuration
- Custom tag functions
- Conditional logging with Skipper
- External logging service integration

**Detailed Tag Reference:**
- Complete list of all available tags (time, request, response, dynamic)
- Clear explanations of each tag's purpose and format
- Examples showing proper usage

**Enhanced Field Documentation:**
- Detailed descriptions for all LoggerConfig fields
- Examples for each configuration option
- Default values and behavior

**Troubleshooting Section:**
- Common issues and solutions
- Performance optimization tips
- Best practices for high-traffic applications

+//   - cookie:<NAME>: Value of specific cookie (e.g., cookie:session_id)
+//   - custom: Output from CustomTagFunc
+//
+// # Troubleshooting
+//
+// ## Common Issues
+//
+// 1. **Missing logs**: Check if Skipper function is filtering out requests
+// 2. **Invalid JSON**: Ensure CustomTagFunc outputs valid JSON content
+// 3. **Performance issues**: Consider using a buffered writer for high-traffic applications
+// 4. **File permission errors**: Ensure write permissions when logging to files
+//
+// ## Performance Tips
+//
+// - Use time_unix formats for better performance than time_rfc3339
+// - Minimize the number of dynamic tags (header:, query:, form:, cookie:)
+// - Use Skipper to exclude high-frequency, low-value requests (health checks, etc.)
+// - Consider async logging for very high-traffic applications

Subject: [PATCH 240/371] Modernize context.go by replacing interface{} with
 any (#2822)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Modernizes the Context interface by replacing all instances of interface{}
with the more readable 'any' type alias introduced in Go 1.18.

**Changes:**
- Replaced interface{} with any in all Context interface method signatures
- Affects Get(), Set(), Bind(), Validate(), Render(), JSON(), JSONP(), XML(),
  Blob(), Stream(), File(), Attachment(), Inline(), and NoContent() methods
- Total of 23 interface{} → any replacements

**Benefits:**
- Improves code readability and modernizes to Go 1.18+ standards
- No functional changes - 'any' is just an alias for interface{}
- Follows current Go best practices for new code
- Makes the API more approachable for developers familiar with modern Go

**Compatibility:**
- Zero breaking changes - 'any' and interface{} are identical
- Maintains full backward compatibility
- All existing code continues to work unchanged

This modernization aligns Echo with current Go conventions while maintaining
100% compatibility with existing applications.

Subject: [PATCH 245/371] Optimize realm quoting to happen once during
 middleware creation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move strconv.Quote(config.Realm) from per-request execution
to middleware initialization for better performance.

- Pre-compute quoted realm at middleware creation time
- Avoids repeated string operations on every auth failure
- Maintains same behavior with better efficiency

Performance improvement suggested during code review.

 # Changelog
 
+## v4.14.0 - 2025-12-xx
+
+**Security**
+
+* Logger middleware: escape string values when logger format looks like JSON
+
+
+**Enhancements**
+
+* Add `middleware.RequestLogger` function to replace `middleware.Logger`. `middleware.RequestLogger` uses default slog logger.
+  Default slog logger output can be configured to JSON format like that:
+  ```go
+  slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
+  e.Use(middleware.RequestLogger())
+  ```
+* Deprecate `middleware.Logger` function and point users to `middleware.RequestLogger` and `middleware.RequestLoggerWithConfig`
+
 ## v4.13.4 - 2025-05-22

 # Changelog
 
-## v4.14.0 - 2025-12-xx
+## v4.14.0 - 2025-12-11
+
+`middleware.Logger` has been deprecated. For request logging, use `middleware.RequestLogger` or
+`middleware.RequestLoggerWithConfig`.
+
+`middleware.RequestLogger` replaces `middleware.Logger`, offering comparable configuration while relying on the
+Go standard library’s new `slog` logger.
+
+The previous default output format was JSON. The new default follows the standard `slog` logger settings.
+To continue emitting request logs in JSON, configure `slog` accordingly:
+```go
+slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
+e.Use(middleware.RequestLogger())
+```
+
 
 **Security**
 
-* Logger middleware: escape string values when logger format looks like JSON
+* Logger middleware json string escaping and deprecation by @aldas in https://github.com/labstack/echo/pull/2849
+
 
 
 **Enhancements**
 
-* Add `middleware.RequestLogger` function to replace `middleware.Logger`. `middleware.RequestLogger` uses default slog logger.
-  Default slog logger output can be configured to JSON format like that:
-  ```go
-  slog.SetDefault(slog.New(slog.NewJSONHandler(os.Stdout, nil)))
-  e.Use(middleware.RequestLogger())
-  ```
-* Deprecate `middleware.Logger` function and point users to `middleware.RequestLogger` and `middleware.RequestLoggerWithConfig`
+* Update deps  by @aldas in https://github.com/labstack/echo/pull/2807
+* refactor to use reflect.TypeFor by @cuiweixie in https://github.com/labstack/echo/pull/2812
+* Use Go 1.25 in CI by @aldas in https://github.com/labstack/echo/pull/2810
+* Modernize context.go by replacing interface{} with any by @vishr in https://github.com/labstack/echo/pull/2822
+* Fix typo in SetParamValues comment by @vishr in https://github.com/labstack/echo/pull/2828
+* Fix typo in ContextTimeout middleware comment by @vishr in https://github.com/labstack/echo/pull/2827
+* Improve BasicAuth middleware: use strings.Cut and RFC compliance by @vishr in https://github.com/labstack/echo/pull/2825
+* Fix duplicate plus operator in router backtracking logic by @yuya-morimoto in https://github.com/labstack/echo/pull/2832
+* Replace custom private IP range check with built-in net.IP.IsPrivate by @kumapower17 in https://github.com/labstack/echo/pull/2835
+* Ensure proxy connection is closed in proxyRaw function(#2837) by @kumapower17 in https://github.com/labstack/echo/pull/2838
+* Update deps by @aldas in https://github.com/labstack/echo/pull/2843

 # Changelog
 
+## v4.15.0 - TBD
+
+**DEPRECATION NOTICE** Timeout Middleware Deprecated - Use ContextTimeout Instead
+
+The `middleware.Timeout` middleware has been **deprecated** due to fundamental architectural issues that cause
+data races. Use `middleware.ContextTimeout` or `middleware.ContextTimeoutWithConfig` instead.
+
+**Why is this being deprecated?**
+
+The Timeout middleware manipulates response writers across goroutine boundaries, which causes data races that
+cannot be reliably fixed without a complete architectural redesign. The middleware:
+
+- Swaps the response writer using `http.TimeoutHandler`
+- Must be the first middleware in the chain (fragile constraint)
+- Can cause races with other middleware (Logger, metrics, custom middleware)
+- Has been the source of multiple race condition fixes over the years
+
+**What should you use instead?**
+
+The `ContextTimeout` middleware (available since v4.12.0) provides timeout functionality using Go's standard
+context mechanism. It is:
+
+- Race-free by design
+- Can be placed anywhere in the middleware chain
+- Simpler and more maintainable
+- Compatible with all other middleware
+
+**Migration Guide:**
+
+```go
+// Before (deprecated):
+e.Use(middleware.Timeout())
+
+// After (recommended):
+e.Use(middleware.ContextTimeout(30 * time.Second))
+```
+
+With configuration:
+```go
+// Before (deprecated):
+e.Use(middleware.TimeoutWithConfig(middleware.TimeoutConfig{
+    Timeout: 30 * time.Second,
+    Skipper: func(c echo.Context) bool {
+        return c.Path() == "/health"
+    },
+}))
+
+// After (recommended):
+e.Use(middleware.ContextTimeoutWithConfig(middleware.ContextTimeoutConfig{
+    Timeout: 30 * time.Second,
+    Skipper: func(c echo.Context) bool {
+        return c.Path() == "/health"
+    },
+}))
+```
+
+**Important Behavioral Differences:**
+
+1. **Handler cooperation required**: With ContextTimeout, your handlers must check `context.Done()` for cooperative
+   cancellation. The old Timeout middleware would send a 503 response regardless of handler cooperation, but had
+   data race issues.
+
+2. **Error handling**: ContextTimeout returns errors through the standard error handling flow. Handlers that receive
+   `context.DeadlineExceeded` should handle it appropriately:
+
+```go
+e.GET("/long-task", func(c echo.Context) error {
+    ctx := c.Request().Context()
+
+    // Example: database query with context
+    result, err := db.QueryContext(ctx, "SELECT * FROM large_table")
+    if err != nil {
+        if errors.Is(err, context.DeadlineExceeded) {
+            // Handle timeout
+            return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
+        }
+        return err
+    }
+
+    return c.JSON(http.StatusOK, result)
+})
+```
+
+3. **Background tasks**: For long-running background tasks, use goroutines with context:
+
+```go
+e.GET("/async-task", func(c echo.Context) error {
+    ctx := c.Request().Context()
+
+    resultCh := make(chan Result, 1)
+    errCh := make(chan error, 1)
+
+    go func() {
+        result, err := performLongTask(ctx)
+        if err != nil {
+            errCh <- err
+            return
+        }
+        resultCh <- result
+    }()
+
+    select {
+    case result := <-resultCh:
+        return c.JSON(http.StatusOK, result)
+    case err := <-errCh:
+        return err
+    case <-ctx.Done():
+        return echo.NewHTTPError(http.StatusServiceUnavailable, "Request timeout")
+    }
+})
+```
+
+

 # Changelog
 
-## v4.15.0 - TBD
+## v4.15.0 - 2026-01-01
+
+
+**Security**
+
+NB: **If your application relies on cross-origin or same-site (same subdomain) requests do not blindly push this version to production**
+
+
+The CSRF middleware now supports the [**Sec-Fetch-Site**](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Sec-Fetch-Site) header as a modern, defense-in-depth approach to [CSRF
+protection](https://cheatsheetseries.owasp.org/cheatsheets/Cross-Site_Request_Forgery_Prevention_Cheat_Sheet.html#fetch-metadata-headers), implementing the OWASP-recommended Fetch Metadata API alongside the traditional token-based mechanism.
+
+**How it works:**
+
+Modern browsers automatically send the `Sec-Fetch-Site` header with all requests, indicating the relationship
+between the request origin and the target. The middleware uses this to make security decisions:
+
+- **`same-origin`** or **`none`**: Requests are allowed (exact origin match or direct user navigation)
+- **`same-site`**: Falls back to token validation (e.g., subdomain to main domain)
+- **`cross-site`**: Blocked by default with 403 error for unsafe methods (POST, PUT, DELETE, PATCH)
+
+For browsers that don't send this header (older browsers), the middleware seamlessly falls back to
+traditional token-based CSRF protection.
+
+**New Configuration Options:**
+- `TrustedOrigins []string`: Allowlist specific origins for cross-site requests (useful for OAuth callbacks, webhooks)
+- `AllowSecFetchSiteFunc func(echo.Context) (bool, error)`: Custom logic for same-site/cross-site request validation
+
+**Example:**
+  ```go
+  e.Use(middleware.CSRFWithConfig(middleware.CSRFConfig{
+      // Allow OAuth callbacks from trusted provider
+      TrustedOrigins: []string{"https://oauth-provider.com"},
+
+      // Custom validation for same-site requests
+      AllowSecFetchSiteFunc: func(c echo.Context) (bool, error) {
+          // Your custom authorization logic here
+          return validateCustomAuth(c), nil
+          // return true, err  // blocks request with error
+          // return true, nil  // allows CSRF request through
+          // return false, nil // falls back to legacy token logic
+      },
+  }))
+  ```

+
+**Type-Safe Generic Parameter Binding**
+
+* Added generic functions for type-safe parameter extraction and context access by @aldas in https://github.com/labstack/echo/pull/2856
+
+  Echo now provides generic functions for extracting path, query, and form parameters with automatic type conversion,
+  eliminating manual string parsing and type assertions.
+
+  **New Functions:**
+  - Path parameters: `PathParam[T]`, `PathParamOr[T]`
+  - Query parameters: `QueryParam[T]`, `QueryParamOr[T]`, `QueryParams[T]`, `QueryParamsOr[T]`
+  - Form values: `FormParam[T]`, `FormParamOr[T]`, `FormParams[T]`, `FormParamsOr[T]`
+  - Context store: `ContextGet[T]`, `ContextGetOr[T]`
+
+  **Supported Types:**
+  Primitives (`bool`, `string`, `int`/`uint` variants, `float32`/`float64`), `time.Duration`, `time.Time`
+  (with custom layouts and Unix timestamp support), and custom types implementing `BindUnmarshaler`,
+  `TextUnmarshaler`, or `JSONUnmarshaler`.
+
+  **Example:**
+  ```go
+  // Before: Manual parsing
+  idStr := c.Param("id")
+  id, err := strconv.Atoi(idStr)
+
+  // After: Type-safe with automatic parsing
+  id, err := echo.PathParam[int](c, "id")
+
+  // With default values
+  page, err := echo.QueryParamOr[int](c, "page", 1)
+  limit, err := echo.QueryParamOr[int](c, "limit", 20)
+
+  // Type-safe context access (no more panics from type assertions)
+  user, err := echo.ContextGet[*User](c, "user")
+  ```

+# Echo v5 Public API Changes
+
+**Comparison between `master` (v4.15.0) and `v5` (v5.0.0-alpha) branches**
+
+Generated: 2026-01-01
+
+---
+
+## Executive Summary
+
+Echo v5 represents a **major breaking release** with significant architectural changes focused on:
+- **Updated generic helpers** to take `*Context` and rename form helpers to `FormValue*`
+- **Simplified API surface** by moving Context from interface to concrete struct
+- **Modern Go patterns** including slog.Logger integration
+- **Enhanced routing** with explicit RouteInfo and Routes types
+- **Better error handling** with simplified HTTPError
+- **New test helpers** via the `echotest` package
+
+### Change Statistics
+
+- **Major Breaking Changes**: 15+
+- **New Functions Added**: 30+
+- **Type Signature Changes**: 20+
+- **Removed APIs**: 10+
+- **New Packages Added**: 1 (`echotest`)
+- **Version Change**: `4.15.0` → `5.0.0-alpha`
+
+---
+
+## Critical Breaking Changes
+
+### 1. **Context: Interface → Concrete Struct**
+
+**v4 (master):**
+```go
+type Context interface {
+    Request() *http.Request
+    // ... many methods
+}
+
+// Handler signature
+func handler(c echo.Context) error
+```
+
+**v5:**
+```go
+type Context struct {
+    // Has unexported fields
+}
+
+// Handler signature - NOW USES POINTER!
+func handler(c *echo.Context) error
+```
+
+**Impact:** 🔴 **CRITICAL BREAKING CHANGE**
+- ALL handlers must change from `echo.Context` to `*echo.Context`
+- Context is now a concrete struct, not an interface
+- This affects every single handler function in user code
+
+**Migration:**
+```go
+// Before (v4)
+func MyHandler(c echo.Context) error {
+    return c.JSON(200, map[string]string{"hello": "world"})
+}
+
+// After (v5)
+func MyHandler(c *echo.Context) error {
+    return c.JSON(200, map[string]string{"hello": "world"})
+}
+```
+
+---
+
+### 2. **Logger: Custom Interface → slog.Logger**
+
+**v4:**
+```go
+type Echo struct {
+    Logger Logger  // Custom interface with Print, Debug, Info, etc.
+}
+
+type Logger interface {
+    Output() io.Writer
+    SetOutput(w io.Writer)
+    Prefix() string
+    // ... many custom methods
+}
+
+// Context returns Logger interface
+func (c Context) Logger() Logger
+```
+
+**v5:**
+```go
+type Echo struct {
+    Logger *slog.Logger  // Standard library structured logger
+}
+
+// Context returns slog.Logger
+func (c *Context) Logger() *slog.Logger
+func (c *Context) SetLogger(logger *slog.Logger)
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Must use Go's standard `log/slog` package
+- Logger interface completely removed
+- All logging code needs updating
+
+---
+
+### 3. **Router: From Router to DefaultRouter**
+
+**v4:**
+```go
+type Router struct { ... }
+
+func NewRouter(e *Echo) *Router
+func (e *Echo) Router() *Router
+```
+
+**v5:**
+```go
+type DefaultRouter struct { ... }
+
+func NewRouter(config RouterConfig) *DefaultRouter
+func (e *Echo) Router() Router  // Returns interface
+```
+
+**Changes:**
+- New `Router` interface introduced
+- `DefaultRouter` is the concrete implementation
+- `NewRouter()` now takes `RouterConfig` instead of `*Echo`
+- Added `NewConcurrentRouter(r Router) Router` for thread-safe routing
+
+---
+
+### 4. **Route Return Types Changed**
+
+**v4:**
+```go
+func (e *Echo) GET(path string, h HandlerFunc, m ...MiddlewareFunc) *Route
+func (e *Echo) Any(path string, h HandlerFunc, m ...MiddlewareFunc) []*Route
+func (e *Echo) Routes() []*Route
+```
+
+**v5:**
+```go
+func (e *Echo) GET(path string, h HandlerFunc, m ...MiddlewareFunc) RouteInfo
+func (e *Echo) Any(path string, h HandlerFunc, m ...MiddlewareFunc) RouteInfo
+func (e *Echo) Match(...) Routes  // Returns Routes type
+func (e *Echo) Router() Router  // Returns interface
+```
+
+**New Types:**
+```go
+type RouteInfo struct {
+    Name       string
+    Method     string
+    Path       string
+    Parameters []string
+}
+
+type Routes []RouteInfo  // Collection with helper methods
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Route registration methods return `RouteInfo` instead of `*Route`
+- New `Routes` collection type with filtering methods
+- `Route` struct still exists but used differently
+
+---
+
+### 5. **Response Type Changed**
+
+**v4:**
+```go
+func (c Context) Response() *Response
+type Response struct {
+    Writer http.ResponseWriter
+    Status int
+    Size   int64
+    Committed bool
+}
+func NewResponse(w http.ResponseWriter, e *Echo) *Response
+```
+
+**v5:**
+```go
+func (c *Context) Response() http.ResponseWriter
+type Response struct {
+    http.ResponseWriter  // Embedded
+    Status    int
+    Size      int64
+    Committed bool
+}
+func NewResponse(w http.ResponseWriter, logger *slog.Logger) *Response
+func UnwrapResponse(rw http.ResponseWriter) (*Response, error)
+```
+
+**Changes:**
+- Context.Response() returns `http.ResponseWriter` instead of `*Response`
+- Response now embeds `http.ResponseWriter`
+- NewResponse takes `*slog.Logger` instead of `*Echo`
+- New `UnwrapResponse()` helper function
+
+---
+
+### 6. **HTTPError Simplified**
+
+**v4:**
+```go
+type HTTPError struct {
+    Internal error
+    Message  interface{}  // Can be any type
+    Code     int
+}
+
+func NewHTTPError(code int, message ...interface{}) *HTTPError
+```
+
+**v5:**
+```go
+type HTTPError struct {
+    Code    int
+    Message string  // Now string only
+    // Has unexported fields (Internal moved)
+}
+
+func NewHTTPError(code int, message string) *HTTPError
+func (he HTTPError) Wrap(err error) error  // New method
+func (he *HTTPError) StatusCode() int      // Implements HTTPStatusCoder
+```
+
+**Changes:**
+- `Message` field changed from `interface{}` to `string`
+- `NewHTTPError()` now takes `string` instead of `...interface{}`
+- Added `HTTPStatusCoder` interface and `StatusCode()` method
+- Added `Wrap(err error)` method for error wrapping
+
+---
+
+### 7. **HTTPErrorHandler Signature Changed**
+
+**v4:**
+```go
+type HTTPErrorHandler func(err error, c Context)
+
+func (e *Echo) DefaultHTTPErrorHandler(err error, c Context)
+```
+
+**v5:**
+```go
+type HTTPErrorHandler func(c *Context, err error)  // Parameters swapped!
+
+func DefaultHTTPErrorHandler(exposeError bool) HTTPErrorHandler  // Now a factory
+```
+
+**Impact:** 🔴 **BREAKING CHANGE**
+- Parameter order reversed: `(c *Context, err error)` instead of `(err error, c Context)`
+- DefaultHTTPErrorHandler is now a factory function that returns HTTPErrorHandler
+- Takes `exposeError` bool to control error message exposure
+
+---
+
+## Notable API Changes in v5
+
+### 1. **Generic Parameter Extraction Functions (Updated Signatures)**
+
+These helpers keep the same generic API but now accept `*Context`, and the
+form helpers are renamed from `FormParam*` to `FormValue*`:
+
+```go
+// Query Parameters
+func QueryParam[T any](c *Context, key string, opts ...any) (T, error)
+func QueryParamOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func QueryParams[T any](c *Context, key string, opts ...any) ([]T, error)
+func QueryParamsOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// Path Parameters
+func PathParam[T any](c *Context, paramName string, opts ...any) (T, error)
+func PathParamOr[T any](c *Context, paramName string, defaultValue T, opts ...any) (T, error)
+
+// Form Values
+func FormValue[T any](c *Context, key string, opts ...any) (T, error)
+func FormValueOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func FormValues[T any](c *Context, key string, opts ...any) ([]T, error)
+func FormValuesOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// Generic Parsing
+func ParseValue[T any](value string, opts ...any) (T, error)
+func ParseValueOr[T any](value string, defaultValue T, opts ...any) (T, error)
+func ParseValues[T any](values []string, opts ...any) ([]T, error)
+func ParseValuesOr[T any](values []string, defaultValue []T, opts ...any) ([]T, error)
+```
+
+`FormParam*` was renamed to `FormValue*`; the rest keep names but now take `*Context`.
+
+**Supported Types:**
+- bool, string
+- int, int8, int16, int32, int64
+- uint, uint8, uint16, uint32, uint64
+- float32, float64
+- time.Time, time.Duration
+- BindUnmarshaler, encoding.TextUnmarshaler, json.Unmarshaler
+
+**Example Usage:**
+```go
+// v5 - Type-safe parameter binding
+id, err := echo.PathParam[int](c, "id")
+page, err := echo.QueryParamOr[int](c, "page", 1)
+tags, err := echo.QueryParams[string](c, "tags")
+```
+
+---
+
+### 2. **Context Store Helpers Now Use `*Context`**
+
+```go
+// Type-safe context value retrieval
+func ContextGet[T any](c *Context, key string) (T, error)
+func ContextGetOr[T any](c *Context, key string, defaultValue T) (T, error)
+
+// Error types
+var ErrNonExistentKey = errors.New("non existent key")
+var ErrInvalidKeyType = errors.New("invalid key type")
+```
+
+These helpers existed in v4 with `Context` and now accept `*Context`.
+
+**Example:**
+```go
+// v5
+user, err := echo.ContextGet[*User](c, "user")
+count, err := echo.ContextGetOr[int](c, "count", 0)
+```
+
+---
+
+### 3. **PathValues Type**
+
+New structured path parameter handling:
+
+```go
+type PathValue struct {
+    Name  string
+    Value string
+}
+
+type PathValues []PathValue
+
+func (p PathValues) Get(name string) (string, bool)
+func (p PathValues) GetOr(name string, defaultValue string) string
+
+// Context methods
+func (c *Context) PathValues() PathValues
+func (c *Context) SetPathValues(pathValues PathValues)
+```
+
+---
+
+### 4. **Time Parsing Options**
+
+```go
+type TimeLayout string
+
+const (
+    TimeLayoutUnixTime      = TimeLayout("UnixTime")
+    TimeLayoutUnixTimeMilli = TimeLayout("UnixTimeMilli")
+    TimeLayoutUnixTimeNano  = TimeLayout("UnixTimeNano")
+)
+
+type TimeOpts struct {
+    Layout          TimeLayout
+    ParseInLocation *time.Location
+    ToInLocation    *time.Location
+}
+```
+
+---
+
+### 5. **StartConfig for Server Configuration**
+
+```go
+type StartConfig struct {
+    Address         string
+    HideBanner      bool
+    HidePort        bool
+    CertFilesystem  fs.FS
+    TLSConfig       *tls.Config
+    ListenerNetwork string
+    ListenerAddrFunc func(addr net.Addr)
+    GracefulTimeout  time.Duration
+    OnShutdownError  func(err error)
+    BeforeServeFunc  func(s *http.Server) error
+}
+
+func (sc StartConfig) Start(ctx context.Context, h http.Handler) error
+func (sc StartConfig) StartTLS(ctx context.Context, h http.Handler, certFile, keyFile any) error
+```
+
+**Example:**
+```go
+// v5 - More control over server startup
+ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
+defer cancel()
+
+sc := echo.StartConfig{
+    Address:         ":8080",
+    GracefulTimeout: 10 * time.Second,
+}
+if err := sc.Start(ctx, e); err != nil {
+    log.Fatal(err)
+}
+```
+
+---
+
+### 6. **Echo Config and Constructors**
+
+```go
+type Config struct {
+    // Configuration for Echo (logger, binder, renderer, etc.)
+}
+
+func NewWithConfig(config Config) *Echo
+```
+
+This adds a configuration struct for creating an `Echo` instance without
+mutating fields after `New()`.
+
+---
+
+### 7. **Enhanced Routing Features**
+
+```go
+// New route methods
+func (e *Echo) AddRoute(route Route) (RouteInfo, error)
+func (e *Echo) Middlewares() []MiddlewareFunc
+func (e *Echo) PreMiddlewares() []MiddlewareFunc
+type AddRouteError struct{ ... }
+
+// Routes collection with filters
+type Routes []RouteInfo
+
+func (r Routes) Clone() Routes
+func (r Routes) FilterByMethod(method string) (Routes, error)
+func (r Routes) FilterByName(name string) (Routes, error)
+func (r Routes) FilterByPath(path string) (Routes, error)
+func (r Routes) FindByMethodPath(method string, path string) (RouteInfo, error)
+func (r Routes) Reverse(routeName string, pathValues ...any) (string, error)
+
+// RouteInfo operations
+func (r RouteInfo) Clone() RouteInfo
+func (r RouteInfo) Reverse(pathValues ...any) string
+```
+
+---
+
+### 8. **Middleware Configuration Interface**
+
+```go
+type MiddlewareConfigurator interface {
+    ToMiddleware() (MiddlewareFunc, error)
+}
+```
+
+Allows middleware configs to be converted to middleware without panicking.
+
+---
+
+### 9. **New Context Methods**
+
+```go
+// v5 additions
+func (c *Context) FileFS(file string, filesystem fs.FS) error
+func (c *Context) FormValueOr(name, defaultValue string) string
+func (c *Context) InitializeRoute(ri *RouteInfo, pathValues *PathValues)
+func (c *Context) ParamOr(name, defaultValue string) string
+func (c *Context) QueryParamOr(name, defaultValue string) string
+func (c *Context) RouteInfo() RouteInfo
+```
+
+---
+
+### 10. **Virtual Host Support**
+
+```go
+func NewVirtualHostHandler(vhosts map[string]*Echo) *Echo
+```
+
+Creates an Echo instance that routes requests to different Echo instances based on host.
+
+---
+
+### 11. **New Binder Functions**
+
+```go
+func BindBody(c *Context, target any) error
+func BindHeaders(c *Context, target any) error
+func BindPathValues(c *Context, target any) error  // Renamed from BindPathParams
+func BindQueryParams(c *Context, target any) error
+```
+
+Top-level binding functions that work with `*Context`.
+
+---
+
+### 12. **New echotest Package**
+
+```go
+package echotest // import "github.com/labstack/echo/v5/echotest"
+
+func LoadBytes(t *testing.T, name string, opts ...loadBytesOpts) []byte
+func TrimNewlineEnd(bytes []byte) []byte
+type ContextConfig struct{ ... }
+type MultipartForm struct{ ... }
+type MultipartFormFile struct{ ... }
+```
+
+Helpers for loading fixtures and constructing test contexts.
+
+---
+
+## Removed APIs in v5
+
+### Constants
+
+```go
+// v4 - Removed in v5
+const CONNECT = http.MethodConnect  // Use http.MethodConnect directly
+```
+
+**Reason:** Deprecated in v4, use stdlib `http.Method*` constants instead.
+
+---
+
+### Constants Added in v5
+
+```go
+// v5 additions
+const (
+    NotFoundRouteName = "echo_route_not_found_name"
+)
+```
+
+---
+
+### Error Variable Changes
+
+**v4 exports:**
+```go
+ErrBadRequest
+ErrInvalidKeyType
+ErrNonExistentKey
+```
+
+**v5 exports:**
+```go
+ErrBadRequest  // Now backed by unexported httpError type
+ErrValidatorNotRegistered  // New
+ErrInvalidKeyType
+ErrNonExistentKey
+```
+
+**Reason:** v5 centralizes on `NewHTTPError(code, message)` rather than a broad set
+of predefined HTTP error variables.
+
+---
+
+### Functions Removed
+
+```go
+// v4 - Removed in v5
+func GetPath(r *http.Request) string  // Use r.URL.Path or r.URL.RawPath
+```
+
+### Variables Removed
+
+```go
+// v4 - Removed in v5
+var MethodNotAllowedHandler = func(c Context) error { ... }
+var NotFoundHandler = func(c Context) error { ... }
+```
+
+### Functions Renamed
+
+```go
+// v4
+func FormParam[T any](c Context, key string, opts ...any) (T, error)
+func FormParamOr[T any](c Context, key string, defaultValue T, opts ...any) (T, error)
+func FormParams[T any](c Context, key string, opts ...any) ([]T, error)
+func FormParamsOr[T any](c Context, key string, defaultValue []T, opts ...any) ([]T, error)
+
+// v5
+func FormValue[T any](c *Context, key string, opts ...any) (T, error)
+func FormValueOr[T any](c *Context, key string, defaultValue T, opts ...any) (T, error)
+func FormValues[T any](c *Context, key string, opts ...any) ([]T, error)
+func FormValuesOr[T any](c *Context, key string, defaultValue []T, opts ...any) ([]T, error)
+```
+
+---
+
+### Type Methods Removed/Changed
+
+**Echo struct changes:**
+```go
+// v4 fields removed in v5
+type Echo struct {
+    StdLogger        *stdLog.Logger  // Removed

+}
+
+// v5 Echo struct (simplified)
+type Echo struct {
+    Binder           Binder
+    Filesystem       fs.FS  // NEW
+    Renderer         Renderer
+    Validator        Validator
+    JSONSerializer   JSONSerializer
+    IPExtractor      IPExtractor
+    OnAddRoute       func(route Route) error  // Simplified
+    HTTPErrorHandler HTTPErrorHandler
+    Logger           *slog.Logger  // Changed from Logger interface
+}
+```
+
+---
+
+**Context interface → struct:**
+```go
+// v4
+type Context interface {
+    // Had: SetResponse(*Response)
+    Response() *Response
+
+    // Had: ParamNames(), SetParamNames(), ParamValues(), SetParamValues()
+    // These are removed in v5 (use PathValues() instead)
+}
+
+// v5
+type Context struct {
+    // Concrete struct with unexported fields
+}
+
+func (c *Context) Response() http.ResponseWriter  // Changed return type
+func (c *Context) PathValues() PathValues         // Replaces ParamNames/Values
+```
+
+---
+
+**Types removed:**
+```go
+// v4
+type Map map[string]interface{}
+```
+
+**Group changes:**
+```go
+// v4
+func (g *Group) File(path, file string)  // No return value
+func (g *Group) Static(pathPrefix, fsRoot string)  // No return value
+func (g *Group) StaticFS(pathPrefix string, filesystem fs.FS)  // No return value
+
+// v5
+func (g *Group) File(path, file string, middleware ...MiddlewareFunc) RouteInfo
+func (g *Group) Static(pathPrefix, fsRoot string, middleware ...MiddlewareFunc) RouteInfo
+func (g *Group) StaticFS(pathPrefix string, filesystem fs.FS, middleware ...MiddlewareFunc) RouteInfo
+```
+
+Now return `RouteInfo` and accept middleware.
+
+---
+
+### Value Binder Factory Name Changes
+
+```go
+// v4
+func PathParamsBinder(c Context) *ValueBinder
+func QueryParamsBinder(c Context) *ValueBinder
+func FormFieldBinder(c Context) *ValueBinder
+
+// v5
+func PathValuesBinder(c *Context) *ValueBinder  // Renamed
+func QueryParamsBinder(c *Context) *ValueBinder
+func FormFieldBinder(c *Context) *ValueBinder
+```
+
+---
+
+## Type Signature Changes
+
+### Binder Interface
+
+```go
+// v4
+type Binder interface {
+    Bind(i interface{}, c Context) error

+```
+
+---
+
+### DefaultBinder Methods

+func (b *DefaultBinder) Bind(i interface{}, c Context) error
+func (b *DefaultBinder) BindBody(c Context, i interface{}) error
+func (b *DefaultBinder) BindPathParams(c Context, i interface{}) error
+
+// v5
+func (b *DefaultBinder) Bind(c *Context, target any) error  // Swapped params

+```
+
+---
+
+### JSONSerializer Interface
+
+```go
+// v4
+type JSONSerializer interface {
+    Serialize(c Context, i interface{}, indent string) error

+}
+
+// v5
+type JSONSerializer interface {
+    Serialize(c *Context, target any, indent string) error
+    Deserialize(c *Context, target any) error
+}
+```
+
+---
+
+### Renderer Interface
+
+```go
+// v4

+}
+
+// v5
+type Renderer interface {
+    Render(c *Context, w io.Writer, templateName string, data any) error
+}
+```
+
+Parameters reordered with Context first.
+
+---
+
+### NewBindingError
+
+```go
+// v4

+```
+
+Message parameter changed from `interface{}` to `string`.
+
+---
+
+### HandlerName
+
+```go
+// v5 only
+func HandlerName(h HandlerFunc) string
+```
+
+New utility function to get handler function name.
+
+---
+
+## Middleware Package Changes
+
+### Signature and Type Updates
+
+```go
+// CORS now accepts optional allow-origins
+func CORS(allowOrigins ...string) echo.MiddlewareFunc
+
+// BodyLimit now accepts bytes
+func BodyLimit(limitBytes int64) echo.MiddlewareFunc

+func CreateExtractors(lookups string, limit uint) ([]ValuesExtractor, error)
+type ValueExtractorError struct{ ... }
+
+// New constants
+const KB = 1024
+
+// Rate limiter store now takes a float64 limit
+func NewRateLimiterMemoryStore(rateLimit float64) (store *RateLimiterMemoryStore)
+```
+
+### Added Middleware Exports
+
+```go

+var RedirectHTTPSWWWConfig = RedirectConfig{ ... }
+var RedirectNonHTTPSWWWConfig = RedirectConfig{ ... }
+var RedirectNonWWWConfig = RedirectConfig{ ... }
+var RedirectWWWConfig = RedirectConfig{ ... }
+```
+
+### Removed/Consolidated Middleware Exports
+
+```go
+// Removed in v5
+func Logger() echo.MiddlewareFunc
+func LoggerWithConfig(config LoggerConfig) echo.MiddlewareFunc
+func Timeout() echo.MiddlewareFunc
+func TimeoutWithConfig(config TimeoutConfig) echo.MiddlewareFunc

+
+---
+
+## Router Interface Changes
+
+### v4 Router (Concrete Struct)
+
+```go
+type Router struct { ... }
+
+func NewRouter(e *Echo) *Router
+func (r *Router) Add(method, path string, h HandlerFunc)
+func (r *Router) Find(method, path string, c Context)
+func (r *Router) Reverse(name string, params ...interface{}) string
+func (r *Router) Routes() []*Route
+```
+
+### v5 Router (Interface + DefaultRouter)
+
+```go
+type Router interface {
+    Add(routable Route) (RouteInfo, error)
+    Remove(method string, path string) error
+    Routes() Routes
+    Route(c *Context) HandlerFunc
+}
+
+type DefaultRouter struct { ... }
+
+func NewRouter(config RouterConfig) *DefaultRouter
+func NewConcurrentRouter(r Router) Router  // NEW
+
+type RouterConfig struct {
+    NotFoundHandler           HandlerFunc
+    MethodNotAllowedHandler   HandlerFunc
+    OptionsMethodHandler      HandlerFunc
+    AllowOverwritingRoute     bool
+    UnescapePathParamValues   bool
+    UseEscapedPathForMatching bool
+}
+```
+
+**Key Changes:**
+- Router is now an interface
+- DefaultRouter is the concrete implementation
+- Add() returns `(RouteInfo, error)` instead of being void
+- New `Remove()` method
+- New `Route()` method replaces `Find()`
+- Configuration through `RouterConfig`
+
+---
+
+## Echo Instance Method Changes
+
+### Route Registration
+
+```go
+// v4
+func (e *Echo) Add(method, path string, handler HandlerFunc, middleware ...MiddlewareFunc) *Route
+
+// v5
+func (e *Echo) Add(method, path string, handler HandlerFunc, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) AddRoute(route Route) (RouteInfo, error)  // NEW
+```
+
+### Static File Serving
+
+```go
+// v4
+func (e *Echo) Static(pathPrefix, fsRoot string) *Route
+func (e *Echo) StaticFS(pathPrefix string, filesystem fs.FS) *Route
+func (e *Echo) File(path, file string, m ...MiddlewareFunc) *Route
+func (e *Echo) FileFS(path, file string, filesystem fs.FS, m ...MiddlewareFunc) *Route
+
+// v5
+func (e *Echo) Static(pathPrefix, fsRoot string, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) StaticFS(pathPrefix string, filesystem fs.FS, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) File(path, file string, middleware ...MiddlewareFunc) RouteInfo
+func (e *Echo) FileFS(path, file string, filesystem fs.FS, m ...MiddlewareFunc) RouteInfo
+```
+
+Return type changed from `*Route` to `RouteInfo`.
+
+### Server Management
+
+```go
+// v4
+func (e *Echo) Start(address string) error
+func (e *Echo) StartTLS(address string, certFile, keyFile interface{}) error
+func (e *Echo) StartAutoTLS(address string) error
+func (e *Echo) StartH2CServer(address string, h2s *http2.Server) error
+func (e *Echo) StartServer(s *http.Server) error
+func (e *Echo) Shutdown(ctx context.Context) error
+func (e *Echo) Close() error
+func (e *Echo) ListenerAddr() net.Addr
+func (e *Echo) TLSListenerAddr() net.Addr
+func (e *Echo) DefaultHTTPErrorHandler(err error, c Context)
+
+// v5
+func (e *Echo) Start(address string) error  // Simplified
+func (e *Echo) ServeHTTP(w http.ResponseWriter, r *http.Request)
+
+// Removed: StartTLS, StartAutoTLS, StartH2CServer, StartServer
+// Use StartConfig instead for advanced server configuration
+// Removed: Shutdown, Close, ListenerAddr, TLSListenerAddr
+// Removed: DefaultHTTPErrorHandler (now a top-level factory function)
+```
+
+**v5 provides** `StartConfig` type for all advanced server configuration.
+
+### Router Access
+
+```go
+// v4
+func (e *Echo) Router() *Router
+func (e *Echo) Routers() map[string]*Router  // For multi-host
+func (e *Echo) Routes() []*Route
+func (e *Echo) Reverse(name string, params ...interface{}) string
+func (e *Echo) URI(handler HandlerFunc, params ...interface{}) string
+func (e *Echo) URL(h HandlerFunc, params ...interface{}) string
+func (e *Echo) Host(name string, m ...MiddlewareFunc) *Group
+
+// v5
+func (e *Echo) Router() Router  // Returns interface
+// Removed: Routers(), Reverse(), URI(), URL(), Host()
+// Use router.Routes() and Routes.Reverse() instead
+```
+
+---
+
+## NewContext Changes
+
+```go
+// v4
+func (e *Echo) NewContext(r *http.Request, w http.ResponseWriter) Context
+func NewResponse(w http.ResponseWriter, e *Echo) *Response
+
+// v5
+func (e *Echo) NewContext(r *http.Request, w http.ResponseWriter) *Context
+func NewContext(r *http.Request, w http.ResponseWriter, opts ...any) *Context  // Standalone
+func NewResponse(w http.ResponseWriter, logger *slog.Logger) *Response
+```
+
+---
+
+## Migration Guide Summary
+
+### 1. Update All Handler Signatures
+
+```go
+// Before
+func MyHandler(c echo.Context) error { ... }
+
+// After
+func MyHandler(c *echo.Context) error { ... }
+```
+
+### 2. Update Logger Usage
+
+```go
+// Before
+e.Logger.Info("Server started")
+c.Logger().Error("Something went wrong")
+
+// After
+e.Logger.Info("Server started")
+c.Logger().Error("Something went wrong")  // Same API, different logger
+```
+
+### 3. Use Type-Safe Parameter Extraction
+
+```go
+// Before
+idStr := c.Param("id")
+id, err := strconv.Atoi(idStr)
+
+// After
+id, err := echo.PathParam[int](c, "id")
+```
+
+### 4. Update Error Handler
+
+```go
+// Before
+e.HTTPErrorHandler = func(err error, c echo.Context) {
+    // handle error
+}
+
+// After
+e.HTTPErrorHandler = func(c *echo.Context, err error) {  // Swapped!
+    // handle error
+}
+
+// Or use factory
+e.HTTPErrorHandler = echo.DefaultHTTPErrorHandler(true)  // exposeError=true
+```
+
+### 5. Update Server Startup
+
+```go
+// Before
+e.Start(":8080")
+e.StartTLS(":443", "cert.pem", "key.pem")
+
+// After
+// Simple
+e.Start(":8080")
+
+// Advanced with graceful shutdown
+ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt)
+defer cancel()
+sc := echo.StartConfig{Address: ":8080"}
+sc.Start(ctx, e)
+```
+
+### 6. Update Route Info Access
+
+```go
+// Before
+routes := e.Routes()
+for _, r := range routes {
+    fmt.Println(r.Method, r.Path)
+}
+
+// After
+routes := e.Router().Routes()
+for _, r := range routes {
+    fmt.Println(r.Method, r.Path)
+}
+```
+
+### 7. Update HTTPError Creation
+
+```go
+// Before
+return echo.NewHTTPError(400, "invalid request", someDetail)
+
+// After
+return echo.NewHTTPError(400, "invalid request")
+```
+
+### 8. Update Custom Binder
+
+```go
+// Before
+type MyBinder struct{}
+func (b *MyBinder) Bind(i interface{}, c echo.Context) error { ... }
+
+// After
+type MyBinder struct{}
+func (b *MyBinder) Bind(c *echo.Context, target any) error { ... }  // Swapped!
+```
+
+### 9. Path Parameters
+
+```go
+// Before
+names := c.ParamNames()
+values := c.ParamValues()
+
+// After
+pathValues := c.PathValues()
+for _, pv := range pathValues {
+    fmt.Println(pv.Name, pv.Value)
+}
+```
+
+### 10. Response Access
+
+```go
+// Before
+resp := c.Response()
+resp.Header().Set("X-Custom", "value")
+
+// After
+c.Response().Header().Set("X-Custom", "value")  // Returns http.ResponseWriter
+
+// To get *echo.Response
+resp, err := echo.UnwrapResponse(c.Response())
+```
+

+# Development Guidelines for middlewares
+
+## Best practices:
+
+* Do not use `panic` in middleware creator functions in case of invalid configuration.
+* In case of an error in middleware function handling request avoid using `c.Error()` and returning no error instead
+  because previous middlewares up in call chain could have logic for dealing with returned errors.
+* Create middleware configuration structs that implement `MiddlewareConfigurator` interface so can decide if they
+  want to create middleware with panics or with returning errors on configuration errors.
+* When adding `echo.Context` to function type or fields make it first parameter so all functions with Context looks same.

-// ContextTimeout Middleware
-//
-// ContextTimeout provides request timeout functionality using Go's context mechanism.

-//
-//
-// Basic Usage:
-//
-//	e.Use(middleware.ContextTimeout(30 * time.Second))
-//
-// With Configuration:
-//
-//	e.Use(middleware.ContextTimeoutWithConfig(middleware.ContextTimeoutConfig{
-//	    Timeout: 30 * time.Second,
-//	    Skipper: middleware.DefaultSkipper,
-//	}))
-//
-// Handler Example:
-//
-//	e.GET("/task", func(c echo.Context) error {
-//	    ctx := c.Request().Context()
-//
-//	    result, err := performTaskWithContext(ctx)

-// LoggerConfig defines the config for Logger middleware.
-//
-// # Configuration Examples
-//
-// ## Basic Usage with Default Settings
-//
-//	e.Use(middleware.Logger())
-//
-// This uses the default JSON format that logs all common request/response details.
-//
-// ## Custom Simple Format
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: "${time_rfc3339_nano} ${status} ${method} ${uri} ${latency_human}\n",
-//	}))
-//
-// ## JSON Format with Custom Fields
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: `{"timestamp":"${time_rfc3339_nano}","level":"info","remote_ip":"${remote_ip}",` +
-//			`"method":"${method}","uri":"${uri}","status":${status},"latency":"${latency_human}",` +
-//			`"user_agent":"${user_agent}","error":"${error}"}` + "\n",
-//	}))
-//
-// ## Custom Time Format
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: "${time_custom} ${method} ${uri} ${status}\n",
-//		CustomTimeFormat: "2006-01-02 15:04:05",
-//	}))
-//
-// ## Logging Headers and Parameters
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: `{"time":"${time_rfc3339_nano}","method":"${method}","uri":"${uri}",` +
-//			`"status":${status},"auth":"${header:Authorization}","user":"${query:user}",` +
-//			`"form_data":"${form:action}","session":"${cookie:session_id}"}` + "\n",
-//	}))
-//
-// ## Custom Output (File Logging)
-//
-//	file, err := os.OpenFile("app.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
-//	if err != nil {
-//		log.Fatal(err)
-//	}
-//	defer file.Close()
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Output: file,
-//	}))
-//
-// ## Custom Tag Function
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: `{"time":"${time_rfc3339_nano}","user_id":"${custom}","method":"${method}"}` + "\n",
-//		CustomTagFunc: func(c echo.Context, buf *bytes.Buffer) (int, error) {
-//			userID := getUserIDFromContext(c) // Your custom logic
-//			return buf.WriteString(strconv.Itoa(userID))
-//		},
-//	}))
-//
-// ## Conditional Logging (Skip Certain Requests)
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Skipper: func(c echo.Context) bool {
-//			// Skip logging for health check endpoints
-//			return c.Request().URL.Path == "/health" || c.Request().URL.Path == "/metrics"
-//		},
-//	}))
-//
-// ## Integration with External Logging Service
-//
-//	logBuffer := &SyncBuffer{} // Thread-safe buffer for external service
-//
-//	e.Use(middleware.LoggerWithConfig(middleware.LoggerConfig{
-//		Format: `{"timestamp":"${time_rfc3339_nano}","service":"my-api","level":"info",` +
-//			`"method":"${method}","uri":"${uri}","status":${status},"latency_ms":${latency},` +
-//			`"remote_ip":"${remote_ip}","user_agent":"${user_agent}","error":"${error}"}` + "\n",
-//		Output: logBuffer,
-//	}))
-//
-// # Available Tags
-//
-// ## Time Tags
-//   - time_unix: Unix timestamp (seconds)
-//   - time_unix_milli: Unix timestamp (milliseconds)
-//   - time_unix_micro: Unix timestamp (microseconds)
-//   - time_unix_nano: Unix timestamp (nanoseconds)
-//   - time_rfc3339: RFC3339 format (2006-01-02T15:04:05Z07:00)
-//   - time_rfc3339_nano: RFC3339 with nanoseconds
-//   - time_custom: Uses CustomTimeFormat field
-//
-// ## Request Information
-//   - id: Request ID from X-Request-ID header
-//   - remote_ip: Client IP address (respects proxy headers)
-//   - uri: Full request URI with query parameters
-//   - host: Host header value
-//   - method: HTTP method (GET, POST, etc.)
-//   - path: URL path without query parameters
-//   - route: Echo route pattern (e.g., /users/:id)
-//   - protocol: HTTP protocol version
-//   - referer: Referer header value
-//   - user_agent: User-Agent header value
-//
-// ## Response Information
-//   - status: HTTP status code
-//   - error: Error message if request failed
-//   - latency: Request processing time in nanoseconds
-//   - latency_human: Human-readable processing time
-//   - bytes_in: Request body size in bytes
-//   - bytes_out: Response body size in bytes
-//
-// ## Dynamic Tags
-//   - header:<NAME>: Value of specific header (e.g., header:Authorization)
-//   - query:<NAME>: Value of specific query parameter (e.g., query:user_id)
-//   - form:<NAME>: Value of specific form field (e.g., form:username)
-//   - cookie:<NAME>: Value of specific cookie (e.g., cookie:session_id)
-//   - custom: Output from CustomTagFunc
-//
-// # Troubleshooting
-//
-// ## Common Issues
-//
-// 1. **Missing logs**: Check if Skipper function is filtering out requests
-// 2. **Invalid JSON**: Ensure CustomTagFunc outputs valid JSON content
-// 3. **Performance issues**: Consider using a buffered writer for high-traffic applications
-// 4. **File permission errors**: Ensure write permissions when logging to files
-//
-// ## Performance Tips
-//
-// - Use time_unix formats for better performance than time_rfc3339
-// - Minimize the number of dynamic tags (header:, query:, form:, cookie:)
-// - Use Skipper to exclude high-frequency, low-value requests (health checks, etc.)
-// - Consider async logging for very high-traffic applications
-type LoggerConfig struct {
-	// Skipper defines a function to skip middleware.
-	// Use this to exclude certain requests from logging (e.g., health checks).
-	//
-	// Example:
-	//	Skipper: func(c echo.Context) bool {
-	//		return c.Request().URL.Path == "/health"
-	//	},
-	Skipper Skipper
-
-	// Format defines the logging format using template tags.
-	// Tags are enclosed in ${} and replaced with actual values.
-	// See the detailed tag documentation above for all available options.
-	//
-	// Default: JSON format with common fields
-	// Example: "${time_rfc3339_nano} ${status} ${method} ${uri} ${latency_human}\n"
-	Format string `yaml:"format"`
-
-	// CustomTimeFormat specifies the time format used by ${time_custom} tag.
-	// Uses Go's reference time: Mon Jan 2 15:04:05 MST 2006
-	//
-	// Default: "2006-01-02 15:04:05.00000"
-	// Example: "2006-01-02 15:04:05" or "15:04:05.000"
-	CustomTimeFormat string `yaml:"custom_time_format"`
-
-	// CustomTagFunc is called when ${custom} tag is encountered.
-	// Use this to add application-specific information to logs.
-	// The function should write valid content for your log format.
-	//
-	// Example:
-	//	CustomTagFunc: func(c echo.Context, buf *bytes.Buffer) (int, error) {
-	//		userID := getUserFromContext(c)
-	//		return buf.WriteString(`"user_id":"` + userID + `"`)
-	//	},
-	CustomTagFunc func(c echo.Context, buf *bytes.Buffer) (int, error)
-
-	// Output specifies where logs are written.
-	// Can be any io.Writer: files, buffers, network connections, etc.
-	//
-	// Default: os.Stdout
-	// Example: Custom file, syslog, or external logging service
-	Output io.Writer
-
-	template *fasttemplate.Template
-	colorer  *color.Color
-	pool     *sync.Pool
-	timeNow  func() time.Time

+Echo `v5` is maintenance release with **major breaking changes** 
+- `Context` is now struct instead of interface and we can add method to it in the future in minor versions.
+- Adds new `Router` interface for possible new routing implementations.
+- Drops old logging interface and uses moderm `log/slog` instead.
+- Rearranges alot of methods/function signatures to make them more consistent.

 Echo v5 represents a **major breaking release** with significant architectural changes focused on:
 - **Updated generic helpers** to take `*Context` and rename form helpers to `FormValue*`

+```bash
+find . -type f -name "*.go" -exec sed -i 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i 's/echo\/v4/echo\/v5/g' {} +

 # Changelog
 
+## v5.0.0 - 2026-01-18
+
+Echo `v5` is maintenance release with **major breaking changes**
+- `Context` is now struct instead of interface and we can add method to it in the future in minor versions.
+- Adds new `Router` interface for possible new routing implementations.
+- Drops old logging interface and uses moderm `log/slog` instead.
+- Rearranges alot of methods/function signatures to make them more consistent.
+
+Upgrade notes and `v4` support:
+- Echo `v4` is supported with **security*** updates and **bug** fixes until **2026-12-31**
+- If you are using Echo in a production environment, it is recommended to wait until after 2026-03-31 before upgrading.
+- Until 2026-03-31, any critical issues requiring breaking `v5` API changes will be addressed, even if this violates semantic versioning.
+
+See [API_CHANGES_V5.md](./API_CHANGES_V5.md) for public API changes between `v4` and `v5`, notes on **upgrading**.
+
+Upgrading TLDR:
+
+If you are using Linux you can migrate easier parts like that:
+```bash
+find . -type f -name "*.go" -exec sed -i 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i 's/echo\/v4/echo\/v5/g' {} +
+```
+macOS
+```bash
+find . -type f -name "*.go" -exec sed -i '' 's/ echo.Context/ *echo.Context/g' {} +
+find . -type f -name "*.go" -exec sed -i '' 's/echo\/v4/echo\/v5/g' {} +
+```
+
+or in your favorite IDE
+
+Replace all:
+1. ` echo.Context` -> ` *echo.Context`
+2. `echo/v4` -> `echo/v5`
+
+This should solve most of the issues. Probably the hardest part is updating all the tests.
+
+

 **Security**
 
-* Fix directory traversal vulnerability under Windows in Static middleware when default Echo filesytem is used (effectively `middleware.StaticConfig{Filesystem: nil}`).
+* Fix directory traversal vulnerability under Windows in Static middleware when default Echo filesystem is used. Reported by @shblue21.
+
+This applies to cases when:
+- Windows is used as OS
+- `middleware.StaticConfig.Filesystem` is `nil` (default)
+- `echo.Filesystem` is has not been set explicitly (default)
+
+Exposure is restricted to the active process working directory and its subfolders.

 # Changelog
 
+## v5.1.0 - 2026-03-31
+
+**Security**
+
+This change does not break the API contract, but it does introduce breaking changes in logic/behavior.
+If your application is using `c.RealIP()` beware and read https://echo.labstack.com/docs/ip-address
+
+`v4` behavior can be restored with:
+```go
+e := echo.New()
+e.IPExtractor = echo.LegacyIPExtractor()
+```
+
+* Remove legacy IP extraction logic from context.RealIP method by @aldas in https://github.com/labstack/echo/pull/2933
+
+
+**Enhancements**
+
+* Add echo-opentelemetry to the README.md by @aldas in https://github.com/labstack/echo/pull/2908
+* fix: correct spelling mistakes in comments and field name by @crawfordxx in https://github.com/labstack/echo/pull/2916
+* Add https://github.com/labstack/echo-prometheus to the middleware list in README.md by @aldas in https://github.com/labstack/echo/pull/2919
+* Add StartConfig.Listener so server with custom Listener is easier to create by @aldas in https://github.com/labstack/echo/pull/2920
+* Fix rate limiter documentation for default burst value by @karesansui-u in https://github.com/labstack/echo/pull/2925
+* Add doc comments to clarify usage of File related methods and leading slash handling by @aldas in https://github.com/labstack/echo/pull/2928
+* Add NewDefaultFS function to help create filesystem that allows absolute paths by @aldas in https://github.com/labstack/echo/pull/2931
+* Do not set http.Server.WriteTimeout in StartConfig by @aldas in https://github.com/labstack/echo/pull/2932
+
+

 ### Supported Echo versions
 
 - Latest major version of Echo is `v5` as of 2026-01-18.
-  - Until 2026-03-31, any critical issues requiring breaking API changes will be addressed, even if this violates
-    semantic versioning.
   - See [API_CHANGES_V5.md](./API_CHANGES_V5.md) for public API changes between `v4` and `v5`, notes on upgrading.
-  - If you are using Echo in a production environment, it is recommended to wait until after 2026-03-31 before
-    upgrading.
 - Echo `v4` is supported with **security*** updates and **bug** fixes until **2026-12-31**

 time.Duration

The non-Must variants (UnixTime, UnixTimeMilli, UnixTimeNano) all say
"binds parameter to time.Time variable", but the three Must* versions
copy-pasted the Duration variant's docstring and say time.Duration.
The function signature on each takes *time.Time. Also dropped the stray
double space and fixed "nano second" -> "nanosecond" on the
Nano one while in there.

Subject: [PATCH 329/371] fix(middleware/proxy): append RealIP to
 X-Forwarded-For for WebSocket requests (#2994)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* <Description>

The proxy middleware's WebSocket path currently sets `X-Forwarded-For` only
when the header is empty, dropping the proxy's own peer IP from the chain
whenever upstream proxies had already added entries. This breaks downstream
services that rely on the "rightmost untrusted" rule to extract the real
client IP, including echo's own `ExtractIPFromXFFHeader`.

The HTTP path delegates to `net/http/httputil.ReverseProxy`, which appends
`RemoteAddr` to the existing `X-Forwarded-For` chain — either inline in
`ServeHTTP`'s default Director path
([reverseproxy.go#L519-L531](https://github.com/golang/go/blob/go1.26.3/src/net/http/httputil/reverseproxy.go#L519-L531))
or via the explicit
[`(*ProxyRequest).SetXForwarded`](https://github.com/golang/go/blob/go1.26.3/src/net/http/httputil/reverseproxy.go#L82-L96)
when a `Rewrite` callback is configured. The WebSocket path uses `proxyRaw`,
which writes the request verbatim via `r.Write(out)`, so this middleware is
the only place where the appending happens for WebSocket Upgrade requests.

<Change>

Replace the "set if empty" guard with always-append. Read values via map
access to preserve multi-line `X-Forwarded-For` headers (RFC 9110 §5.3
allows combining them by joining values with commas).

<Test>
Added TestProxyWebSocketXForwardedFor exercising 4 cases:

- no incoming X-Forwarded-For → only c.RealIP()
- single-line single-entry → preserved + c.RealIP() at the tail
- ingle-line comma-separated → preserved + c.RealIP() at the tail
- multi-line headers (multiple X-Forwarded-For occurrences) → joined with , + c.RealIP() at the tail

Each case captures the request header at WebSocket Upgrade time inside the
upstream handler and asserts both the appended tail and the preserved prefix.

<Backwards compatibility>
The change is additive: existing entries are preserved and the proxy's own
peer IP is added at the tail. Downstream readers using the standard
"rightmost untrusted" rule (e.g. echo.ExtractIPFromXFFHeader) see no
behavioral difference for chains where they already worked, and start
returning the correct IP for chains where the proxy IP was previously
dropped.

<Background>
We hit this in production with an Echo-based WebSocket reverse proxy
fronting an internal service that uses echo.ExtractIPFromXFFHeader for
IP-based authorization. Multi-hop deployments (customer proxy → our reverse
proxy → backend) broke because the reverse proxy's egress IP was missing
from the chain reaching the backend.

* Set up upstream per test

Subject: [PATCH 331/371] docs: liveness signals in README + public ROADMAP
 (#3002)

* docs: add liveness signals to README and a public ROADMAP

- Add dynamic latest-release and last-commit badges (can't go stale)
- Add positioning vs net/http and an "actively maintained" note
- Add ROADMAP.md with version policy (v5 current, v4 LTS to 2026-12-31)
  and surface it from the README

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs: fix review findings in README/ROADMAP

- Correct net/http interop claim: Echo handlers are not http.Handler;
  interop is via WrapHandler/WrapMiddleware
- Clarify binding ships with a pluggable validator (not built-in validation)
- ROADMAP: reference canonical auto-HEAD issue/PR (#2895/#2949) instead of
  the duplicate PRs (#2944/#2937) slated for closure

+# Echo Roadmap
+
+> **DRAFT** — this is a starting point for maintainers to edit, not a commitment.
+> Dates and priorities are owned by the Echo team. Open a discussion to propose changes.
+
+This document exists so the community can see where Echo is heading. Echo is
+**actively maintained**. We publish releases regularly across two supported
+lines — see [README](./README.md) badges for the latest version and most recent commit.
+
+## Version policy
+
+| Line | Status | Support |
+|------|--------|---------|
+| `v5` | **Current** (since 2026-01-18) | New features, fixes, and improvements. |
+| `v4` | Maintenance / LTS | **Security and bug fixes until 2026-12-31.** No new features. |
+
+Upgrading from v4? See [API_CHANGES_V5.md](./API_CHANGES_V5.md).
+
+Echo supports the **latest four Go major releases** and may work with older versions.
+
+## Now (in progress)
+
+- Stabilizing the `v5` API surface through point releases.
+- Documentation catch-up for v5 behavior changes (e.g. CORS / `RouteNotFound`
+  behavior on groups — see #2950).
+- Triaging and reducing the open issue / PR backlog.
+
+## Next (under consideration)
+
+These are frequently-requested items being discussed. Inclusion here is **not** a
+commitment — each still needs design agreement before implementation:
+
+- **Automatic `HEAD` for `GET` routes** (#2895; see #2949) — opt-in, likely via an
+  `OnAddRoute` hook so users keep control.
+- **Rate limiter response metadata** — expose `Retry-After` / remaining quota
+  through the store interface (#2961).
+- **Real-IP / `Forwarded` header handling** improvements (#2744).
+- **Proxy middleware** authorization-header handling (#2787).
+
+## Later / exploratory
+
+- Continued alignment with the Go standard library (`net/http`, `slog`).
+- Reducing third-party surface where the stdlib now covers the need.
+
+## How to influence the roadmap
+
+- **Discuss before large PRs** — open a [Discussion](https://github.com/labstack/echo/discussions)
+  or issue so we can agree on the design first.
+- 👍 reactions on issues help us gauge demand.
+- See [README → Contribute](./README.md#contribute) for contribution guidelines.

Subject: [PATCH 332/371] test: lock in v5 group route method-handling (405 +
 OPTIONS) (#3003)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* test: guard group catch-all against 405-masking and route shadowing

Adds regression tests around automatic group catch-all (404) route
registration. v5 removed that auto-registration; if it is restored
(e.g. PR #2996) these tests ensure it does not bring back the issues
that motivated the removal:

- wrong HTTP method on an existing group route must still return 405
  (with Allow header), not be masked to 404 by the catch-all;
- the group catch-all must not shadow concrete sibling routes, root
  routes, or other sibling groups' routes.

All four pass on current master (v5). The 405 test fails against the
restore-v4-behavior approach in #2996, pinning down that tradeoff.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* test: rewrite group method-handling tests after review

Addresses review of the original regression file (PR #3003): its comments
described an automatic group catch-all "triggered by middleware" that does
not exist on master (v5), so the tests passed for the wrong reason and the
no-op middleware was inert.

Rewrite to assert v5's actual, verified behavior:
- method mismatch on a group route -> 405 with full Allow header
- OPTIONS on a registered group route -> 204 with Allow (preflight-relevant)
- concrete routes resolve; group prefix does not affect root routes

The 405 and OPTIONS tests are real gates: a group-level catch-all (manual or
the auto-registration proposed in #2996) masks both as 404, which these tests
would then catch. Drops the false premise, the inert middleware, and the
in-comment PR reference.

* test: add rewritten group method-handling tests

The previous commit recorded only the deletion of the old file; this adds
the rewritten suite (group_method_handling_test.go).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* test: add companion test demonstrating group catch-all masking

Addresses final review: converts the "verified empirically" comment into an
actual test. TestGroupRoute_catchAllMasksMethodHandling registers a group-wide
catch-all and asserts it masks both the 405 method-mismatch and the automatic
OPTIONS (204) response as 404 — the regression the 405/OPTIONS gate tests guard
against. Makes the rationale self-proving in-repo.

Subject: [PATCH 333/371] fix(binder): serialize BindingError to structured
 JSON (#2771) (#3004)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(binder): serialize BindingError to structured JSON (#2771)

BindingError embeds *HTTPError but did not implement json.Marshaler, so
DefaultHTTPErrorHandler's type switch fell through to its default branch
(the value is a *BindingError, not a *HTTPError), flattening responses to
{"message":"Bad Request"} and dropping both the field name and the binder
message — a regression from fbfe216.

Implement MarshalJSON on *BindingError so it takes the handler's
json.Marshaler branch, restoring the structured {"field":...,"message":...}
response (the v4.10.2 behavior).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* docs/test(binder): clarify BindingError JSON + cover empty-message fallback (#2771)

- Note on the struct that serialization goes through MarshalJSON (the json
  tags are documentation only now).
- Add a test for the empty-message -> status-text fallback branch.

Subject: [PATCH 334/371] fix(binder): include field name in form/struct bind
 conversion errors (#2629) (#3005)

bindData had the field name (inputFieldName) in scope but returned bare
conversion errors, so c.Bind() failures gave no indication of which field
failed (e.g. "strconv.ParseInt: parsing \"10a\"..."). Wrap the conversion
errors with the field name using %w so errors.Is/As still work.

Matches the wrap proposed by the reporter in the issue thread. Existing
tests that asserted the bare message are updated to the field-prefixed form.

Subject: [PATCH 335/371] fix(middleware/static): don't double-unescape request
 path (#2599) (#3006)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(middleware/static): don't double-unescape request path (#2599)

http.Request.URL.Path is already decoded by net/http, but the static
middleware unescaped it again by default, so files whose names contain a
percent sign were not downloadable ("/100%25.txt" -> "invalid URL escape").

Default pathUnescape to false; only the wildcard param from a group route
(set explicitly below) may still be escaped and is handled by the existing
DisablePathUnescaping toggle.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* test(static): add percent-encoded traversal-protection case (#2599)

Companion test confirming that defaulting pathUnescape to false does not
weaken traversal protection — single-, double-, and dot-encoded "../" all
stay within the served root.

Compile middleware chains once, zero-copy String/HTML/JSONP writes, reuse delayedStatusWriter + context store map, single-key QueryParam fast path, per-type bind metadata cache, precomputed HSTS header, pooled request-ID buffers. No public API changes. Also de-flakes TestStartConfig_WithListenerNetwork (ephemeral port).

Subject: [PATCH 337/371] feat(middleware): optional RateLimiterStoreContext
 for response headers (#2961) (#3007)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* feat(middleware): optional RateLimiterStoreContext for response headers (#2961)

Adds an optional RateLimiterStoreContext interface. When the configured store
implements AllowContext(c, identifier), the rate limiter calls it instead of
Allow, giving the store access to the request context so it can set response
headers such as Retry-After / X-RateLimit-*. Fully backward compatible: stores
implementing only Allow are unchanged.

This is the optional-interface approach proposed by the maintainer in the issue
thread; it does not alter the existing Allow interface or the built-in store.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(middleware): set X-RateLimit-* / Retry-After from built-in store (#2961)

Implements AllowContext on RateLimiterMemoryStore so the default store sets
X-RateLimit-Limit, X-RateLimit-Remaining, and (on deny) Retry-After headers
out of the box — mirroring the v4 PR #2985 by @leno23 on the v5 line.

Allow() is refactored to share an internal allow() with AllowContext; the
optional RateLimiterStoreContext interface (added earlier in this PR) routes
the middleware to AllowContext when the store implements it.

 # Changelog
 
+## v5.2.0 - 2026-06-14
+
+**Security**
+
+* fix(static): reject encoded path separators that bypass route-level middleware by @vishr in https://github.com/labstack/echo/pull/3009
+* fix(middleware/static): don't double-unescape request path (#2599) by @vishr in https://github.com/labstack/echo/pull/3006
+
+Fixes [GHSA-vfp3-v2gw-7wfq](https://github.com/labstack/echo/security/advisories/GHSA-vfp3-v2gw-7wfq): an encoded path separator (`%2F` or `%5C`) in a static file URL could bypass route-level middleware (e.g. authentication on a sibling route) and disclose static files. Both `StaticDirectoryHandler`/`StaticFS` and the `Static` middleware are affected. Thanks to @a-tt-om and @oran-gugu for reporting.
+
+**Enhancements**
+
+* feat(middleware): optional RateLimiterStoreContext for response headers (#2961) by @vishr in https://github.com/labstack/echo/pull/3007
+* perf: optimize core hot paths (chain, context, binding, responses) by @vishr in https://github.com/labstack/echo/pull/3008
+* fix(binder): include field name in bind conversion errors (#2629) by @vishr in https://github.com/labstack/echo/pull/3005
+* fix(binder): serialize BindingError to structured JSON (#2771) by @vishr in https://github.com/labstack/echo/pull/3004
+* fix(binder): MustUnixTime docs say time.Time, not time.Duration by @c-tonneslan in https://github.com/labstack/echo/pull/2988
+* fix(middleware): reset ContentLength after gzip decompression by @shblue21 in https://github.com/labstack/echo/pull/3000
+* fix(middleware/proxy): append RealIP to X-Forwarded-For for WebSocket requests by @kawaway in https://github.com/labstack/echo/pull/2994
+* Fix proxy panic when balancer has no targets by @shblue21 in https://github.com/labstack/echo/pull/2977
+* fix(middleware): correct documented KeyAuth KeyLookup default by @leestana01 in https://github.com/labstack/echo/pull/2992
+* test: lock in v5 group route method-handling (405 + OPTIONS) by @vishr in https://github.com/labstack/echo/pull/3003
+* docs: liveness signals in README + public ROADMAP by @vishr in https://github.com/labstack/echo/pull/3002
+* Fix typos in CSRFConfig comments by @shblue21 in https://github.com/labstack/echo/pull/2979
+* refactor: modernize code usage using gofix by @kumapower17 in https://github.com/labstack/echo/pull/2970

Subject: [PATCH 341/371] perf(json): pooled-buffer JSON deserialize (#3023)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* perf(json): reuse pooled buffer for JSON deserialization

DefaultJSONSerializer.Deserialize used json.NewDecoder(body).Decode(),
which allocates a decoder and its internal read buffer on every JSON
request. Read the body into a capped pooled buffer and decode with
json.Unmarshal instead; Unmarshal does not retain the input slice, so the
buffer is safe to reuse. The pool drops oversized buffers (>64 KiB) so a
large body cannot pin memory.

BenchmarkBind_JSON: 1008 B -> 312 B/op (-69%), 9 -> 7 allocs, ~12% faster.

Behavioral note: json.Unmarshal is stricter than Decode — it rejects
trailing data after the JSON value and reports "unexpected end of JSON
input" for truncated bodies (both still 400 Bad Request). Two bind tests
asserting the old "unexpected EOF" message are updated to match.

Also add a general ServeHTTP/JSON benchmark suite (perf_bench_test.go):
BenchmarkBind_JSON now builds the request once and resets a reusable body
instead of calling httptest.NewRequest inside the loop (which dominated
the old measurement), plus BenchmarkJSONSerialize/Deserialize and the
routing benchmarks used to measure both this and the companion router PR.

* test(json): cover pooled-buffer Deserialize behaviors

Add correctness coverage for the new pooled-buffer JSON deserializer,
addressing gaps surfaced in review:

- RejectsTrailingData: documents that json.Unmarshal rejects content after
  the first top-level value (a behavior change from streaming json.Decoder).
- PooledBufferReuse: long body followed by a short one must not leak stale
  bytes through the reused buffer.
- PooledBufferConcurrent: many goroutines decoding distinct bodies; under
  -race this catches any aliasing/missing-reset regression (data bleed).
- LargeBodyThenNormal: exercises the >64 KiB buffer-cap path and that the
  oversized buffer does not corrupt the next request.
- BodyReadError: a failing body read surfaces as 400, matching prior behavior.

Subject: [PATCH 342/371] perf(router): cache-friendly static child lookup +
 dedupe leaf check (#3024)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

findStaticChild scanned []*node and dereferenced every child to read its
one-byte label — a pointer chase per static step. Maintain a parallel
scLabels []byte (kept in sync in addStaticChild, newNode, the insert
split, and Remove) and scan that contiguous slice instead, indexing into
staticChildren only on a hit.

  benchstat (n=6):
  RouterStaticRoutes-14   8.49µ -> 8.01µ   -5.67%  (p=0.002)
  RouterGitHubAPI-14      16.93µ -> 16.45µ  -2.86%  (p=0.002)
  RouterParseAPI / GooglePlusAPI: neutral (param-heavy)
  allocations: 0, unchanged

Also fold the is-leaf recomputation (duplicated across 5 sites, with the
Remove copy subtly using len()==0 vs == nil) into a single refreshLeaf()
helper that uses len() so it is correct whether staticChildren is nil or
an emptied-but-non-nil slice left after a removal.

Split out of #3023 so the router and JSON changes can be reviewed
independently (requested by @aldas).

Subject: [PATCH 347/371] feat: add support for HTTP QUERY method (#3036)

Add first-class support for the QUERY HTTP method (RFC 10008) so it can
be registered with dedicated helpers instead of the generic `Add`.

QUERY is not (yet) part of the `net/http` standard library, so it is
defined in Echo the same way the existing non-standard PROPFIND and
REPORT methods are handled:

- add the `QUERY` method constant
- add `Echo.QUERY` and `Group.QUERY` route helpers
- give QUERY a dedicated field in `routeMethods` and wire it into
  `set`, `find`, `updateAllowHeader` and `isHandler`
- bind URL query parameters for QUERY (like GET/DELETE/HEAD), since
  QUERY is semantically a GET carrying its query in the body

Closes #3036

 Echo `v5` is maintenance release with **major breaking changes** 
 - `Context` is now struct instead of interface and we can add method to it in the future in minor versions.
 - Adds new `Router` interface for possible new routing implementations.
-- Drops old logging interface and uses moderm `log/slog` instead.
-- Rearranges alot of methods/function signatures to make them more consistent.

 # Changelog
 
+## v5.3.0 - 2026-07-12
+
+**Logic changes**
+PR [#2996](https://github.com/labstack/echo/pull/2996) revert back to `v4` behavior for a group registering implicit 404 handlers. 
+
+If you do not want this behavior, can do not want implicit 404 handlers for groups, use:
+```go
+e :=  echo.NewWithConfig(echo.Config{NoGroupAutoRegister404Routes: true})
+g := e.Group("/api")
+```
+
+some other noteworthy echancements:
+* Adds first-class support for the QUERY HTTP method [RFC 10008](https://www.rfc-editor.org/info/rfc10008/) in https://github.com/labstack/echo/pull/3038
+```go
+e.QUERY("/", func(c *Context) error {
+  return c.String(http.StatusTeapot, "OK")
+})
+```
+
+* Router: automatically handle HEAD request by GET handlers in https://github.com/labtack/echo/pull/2949
+```go
+e := echo.NewWithConfig(echo.Config{
+  Router: echo.NewRouter(echo.RouterConfig{
+    AutoHandleHEAD: true,
+  }),
+})
+```
+
+**Enhancements**
+
+* perf(json): pooled-buffer JSON deserialize by @vishr in https://github.com/labstack/echo/pull/3023
+* perf(router): cache-friendly static child lookup by @vishr in https://github.com/labstack/echo/pull/3024
+* update golang.org/x deps to latest versions by @aldas in https://github.com/labstack/echo/pull/3034
+* pin GitHub Actions to full commit SHAs and rework actions SHAs to own variables by @aldas in https://github.com/labstack/echo/pull/3035
+* docs(csrf): fix godoc typo in Generator default (tp -> to) by @DucMinhNe in https://github.com/labstack/echo/pull/3026
+* docs(cors): note reverse-proxy header duplication by @vishr in https://github.com/labstack/echo/pull/3027
+* feat: add support for HTTP QUERY method by @thdxg in https://github.com/labstack/echo/pull/3038
+* docs: fix typos in API_CHANGES_V5.md by @maxtaran2010 in https://github.com/labstack/echo/pull/3039

+* Revert back to v4 behavior for group registering implicit 404 handler… by @aldas in https://github.com/labstack/echo/pull/2996
+
+
+## v5.2.1 - 2026-06-15
+
+**Security**
+
+Make serving static file releated methods and middleware not unescape path by default - so how the way Router interprets paths and Static methods/middleware is consistent.
+
+Given following situation:
+```go
+// 0.
+// given folder structure:
+// private.txt
+// public/
+// public/index.html
+// public/text.txt
+// public/admin/private.txt
+
+// 1. share `public/` folder contents from the server root. This folder actually contains subfolder `admin` which
+// contents we want to forbid from downloading
+e.Static("/", "public")
+
+// 2. naively assume that everything under /admin folder is now forbidden
+e.GET("/admin/*", func(c *Context) error {
+    return ErrForbidden
+})
+```
+
+Then requests to `/admin%2fprivate.txt` would not be matched to `GET /admin/*` route (routing does not look unescaped path) and static file serving will use unescaped path to serve the file.
+
+Note: this way of "guarding" subfolders will never work for for paths like `/assets/../admin%2fprivate.txt` which will `path.Clean("/assets/../admin%2fprivate.txt")` to `/admin/private.txt` and are servable if static file serving is configured to unescape paths.
+
+If you want to guard routes - use middlewares on `Static*` methods and before `Static` middleware.
+
+
+------
+
+* revert PR #3009 changes to just disabling path escaping by default in static methods/middleware by @aldas in https://github.com/labstack/echo/pull/3016
+
+Closes [GHSA-vfp3-v2gw-7wfq](https://github.com/labstack/echo/security/advisories/GHSA-vfp3-v2gw-7wfq) more completely: the previous fix (#3009) rejected explicitly encoded
+separators at the handler level; this patch makes the no-unescape behavior the **default** so new configurations are safe without extra opt-out steps.
+
+**What changed:** `DisablePathUnescaping` (on `StaticConfig` and `StaticDirectoryHandlerConfig`) is deprecated and replaced by `EnablePathUnescaping` (default `false`). Path unescaping is now opt-in.
+
+**What this protects:** With `EnablePathUnescaping: false` (new default), encoded separators (`%2F`, `%5C`) are never decoded before routing or file lookup, so they cannot
+bypass route-level authentication or other middleware guards.
+
+**What this does NOT protect:** Serving a directory with `Static`, `StaticFS`, or `StaticDirectoryHandler` exposes its **entire subtree**. Sibling routes are not a reliable
+ACL boundary — attach authorization middleware directly to the static mount, or serve sensitive sub-trees under separate guarded routes.
+
+**Breaking change / migration:** If you serve files whose names contain URL-encoded characters (e.g., `/hello%20world.txt` → `hello world.txt`), you must now opt in:
+
+ ```go
+ // Static middleware
+ e.Use(middleware.StaticWithConfig(middleware.StaticConfig{
+     EnablePathUnescaping: true, // only safe when NOT relying on route-based ACL guards
+     ...
+ }))
+
+ // StaticDirectoryHandler
+ middleware.StaticDirectoryHandler(fs, &middleware.StaticDirectoryHandlerConfig{
+     EnablePathUnescaping: true,
+ })
+```
+
+

+# Echo
+
+> Echo is a high performance, extensible, minimalist Go web framework built on the standard `net/http` library. The current release line is **v5**, which introduces major breaking changes from v4. Echo adds a fast radix-tree router, request binding with pluggable validator, a deep middleware ecosystem, centralized error handling, and template rendering on top of the standard library.
+
+Key facts for LLMs:
+- Import path is `github.com/labstack/echo/v5` (NOT `github.com/labstack/echo` which is v4)
+- Handlers use `*echo.Context` (pointer to struct), NOT `echo.Context` (interface) like v4
+- `Context` is a concrete struct in v5, not an interface
+- Logging uses `log/slog`, not the old custom `Logger` interface
+- Go 1.25+ required
+
+## Quick Reference
+
+- [Echo v5 API Changes](https://github.com/labstack/echo/blob/master/API_CHANGES_V5.md): Complete v4-to-v5 migration guide with all breaking changes
+- [Echo Official Docs](https://echo.labstack.com): Human-readable documentation site
+- [pkg.go.dev](https://pkg.go.dev/github.com/labstack/echo/v5): API reference on Go package discovery
+
+## Core Patterns (v5)
+
+### Server setup
+
+```go
+package main
+
+import (
+    "log/slog"
+    "net/http"
+
+    "github.com/labstack/echo/v5"
+    "github.com/labstack/echo/v5/middleware"
+)
+
+func hello(c *echo.Context) error {
+    return c.String(http.StatusOK, "Hello, World!")
+}
+
+func main() {
+    e := echo.New()
+    e.Use(middleware.RequestLogger())
+    e.Use(middleware.Recover())
+    e.GET("/", hello)
+    if err := e.Start(":8080"); err != nil {
+        slog.Error("failed to start server", "error", err)
+    }
+}
+```
+
+### Handler signature (v5 vs v4)
+
+```go
+// v5 - pointer to struct
+func handler(c *echo.Context) error {
+    return c.JSON(http.StatusOK, map[string]string{"hello": "world"})
+}
+
+// v4 (DO NOT USE in v5) - interface
+func handler(c echo.Context) error { ... }
+```
+
+### Route registration
+
+```go
+e := echo.New()
+e.GET("/users/:id", getUser)
+e.POST("/users", createUser)
+e.PUT("/users/:id", updateUser)
+e.DELETE("/users/:id", deleteUser)
+
+// Group routes
+g := e.Group("/api/v1")
+g.GET("/posts", listPosts)
+g.POST("/posts", createPost)
+
+// Group with middleware
+admin := e.Group("/admin", middleware.BasicAuth(basicAuthValidator))
+admin.GET("/stats", getStats)
+```
+
+### Generic parameter extraction (v5 new)
+
+```go
+// Type-safe path params
+id, err := echo.PathParam[int](c, "id")
+name, err := echo.PathParam[string](c, "name")
+
+// Query params with defaults
+page, err := echo.QueryParamOr[int](c, "page", 1)
+tags, err := echo.QueryParams[string](c, "tags")
+
+// Form values (renamed from FormParam* in v4)
+val, err := echo.FormValue[string](c, "field")
+val2, err := echo.FormValueOr[string](c, "field", "default")
+
+// Supported types: bool, string, int/int8/.../int64, uint/.../uint64,
+// float32/float64, time.Time, time.Duration
+```
+
+### Request binding
+
+```go
+type User struct {
+    Name  string `json:"name"`
+    Email string `json:"email"`
+}
+
+func createUser(c *echo.Context) error {
+    u := new(User)
+    if err := c.Bind(u); err != nil {
+        return echo.NewHTTPError(http.StatusBadRequest, "invalid request body")
+    }
+    if err := c.Validate(u); err != nil {
+        return err
+    }
+    return c.JSON(http.StatusCreated, u)
+}
+```
+
+### Error handling (v5 changed)
+
+```go
+// v5 - NewHTTPError takes string, not interface{}
+err := echo.NewHTTPError(http.StatusBadRequest, "invalid input")
+
+// v5 - HTTPErrorHandler signature changed (params swapped, pointer)
+e.HTTPErrorHandler = func(c *echo.Context, err error) {
+    // custom error handling
+}
+
+// v5 - DefaultHTTPErrorHandler is now a factory
+e.HTTPErrorHandler = echo.DefaultHTTPErrorHandler(true) // exposeError bool
+```
+
+### Logging (v5 uses slog)
+
+```go
+// v5 - standard library slog
+e.Logger = slog.Default()
+
+// In handlers
+c.Logger().Info("request", "path", c.Path(), "method", c.Request().Method)
+
+// Custom logger
+logger := slog.New(slog.NewJSONHandler(os.Stdout, nil))
+e.Logger = logger
+```
+
+### Middleware
+
+```go
+// Built-in middleware
+e.Use(middleware.RequestLogger())
+e.Use(middleware.Recover())
+e.Use(middleware.CORS())
+e.Use(middleware.Gzip())
+e.Use(middleware.BasicAuth(func(c *echo.Context, username, password string) (bool, error) {
+    return username == "admin" && password == "secret", nil
+}))
+e.Use(middleware.RateLimiter(middleware.NewRateLimiterMemoryStore(20)))
+
+// Route-level middleware
+e.GET("/sensitive", handler, middleware.RequestID(), middleware.Logger())
+```
+
+### Response helpers
+
+```go
+c.String(http.StatusOK, "text")
+c.JSON(http.StatusOK, data)
+c.JSONPretty(http.StatusOK, data, "  ")
+c.XML(http.StatusOK, data)
+c.Blob(http.StatusOK, "image/png", bytes)
+c.Stream(http.StatusOK, "text/event-stream", reader)
+c.File("path/to/file")
+c.FileFS("file.txt", filesystem)
+c.Attachment("path/to/file", "download.txt")
+c.Redirect(http.StatusFound, "/new-path")
+c.NoContent(http.StatusOK)
+c.HTML(http.StatusOK, "<h1>Hello</h1>")
+```
+
+### Static files
+
+```go
+e.Static("/assets", "public")
+e.StaticFS("/static", filesystem)
+e.File("/robots.txt", "robots.txt")
+e.FileFS("file.txt", filesystem)
+```
+
+### Context store (v5 type-safe)
+
+```go
+// Set and get values on context
+c.Set("user", user)
+val, err := echo.ContextGet[*User](c, "user")
+count, err := echo.ContextGetOr[int](c, "count", 0)
+```
+
+### Graceful shutdown with StartConfig (v5 new)
+
+```go
+ctx, cancel := signal.NotifyContext(context.Background(), os.Interrupt, syscall.SIGTERM)
+defer cancel()
+
+sc := echo.StartConfig{
+    Address:        ":8080",
+    GracefulTimeout: 10 * time.Second,
+}
+if err := sc.Start(ctx, e); err != nil {
+    log.Fatal(err)
+}
+```
+
+## v4 to v5 Migration Checklist
+
+1. Change import from `github.com/labstack/echo` to `github.com/labstack/echo/v5`
+2. Change all handler signatures from `echo.Context` to `*echo.Context`
+3. Replace custom `Logger` interface with `log/slog`
+4. Update `HTTPErrorHandler` signature: `func(c *echo.Context, err error)` (params swapped)
+5. `NewHTTPError(code int, message string)` - message is now `string` not `interface{}`
+6. `FormParam*` renamed to `FormValue*`
+7. `PathParamsBinder` renamed to `PathValuesBinder`
+8. `Context.Response()` returns `http.ResponseWriter` instead of `*Response`
+9. `ParamNames()`/`ParamValues()` replaced by `PathValues()`
+10. Use `StartConfig` for server configuration instead of `Echo` struct fields
+11. Route methods return `RouteInfo` instead of `*Route`
+12. `Map` type removed - use `map[string]any` directly
+13. HTTP method constants removed - use `http.MethodGet`, `http.MethodPost`, etc.
+14. `BindPathParams` renamed to `BindPathValues`

+# Echo
+
+> Echo is a high performance, extensible, minimalist Go web framework built on the standard `net/http` library. The current release line is **v5**, which introduces major breaking changes from v4. Echo adds a fast radix-tree router, request binding with pluggable validator, a deep middleware ecosystem, centralized error handling, and template rendering on top of the standard library.
+
+Import path: `github.com/labstack/echo/v5`
+Go version: 1.25+
+Handler signature: `func(c *echo.Context) error`
+
+## Critical v5 Breaking Changes
+
+### 1. Context: interface to struct
+
+v4: `type Context interface` with handler `func(c echo.Context) error`
+v5: `type Context struct` with handler `func(c *echo.Context) error`
+
+ALL handlers must use `*echo.Context` (pointer). The `Context` type is no longer an interface.
+
+### 2. Logger: custom interface to slog
+
+v4: `e.Logger` is a custom `Logger` interface with `Print`, `Debug`, `Info`, etc.
+v5: `e.Logger` is `*slog.Logger` from the standard library `log/slog` package.
+
+```go
+e.Logger = slog.Default()
+c.Logger().Info("message", "key", "value")
+```
+
+### 3. HTTPErrorHandler: parameters swapped
+
+v4: `type HTTPErrorHandler func(err error, c Context)`
+v5: `type HTTPErrorHandler func(c *Context, err error)`
+
+`DefaultHTTPErrorHandler` is now a factory: `echo.DefaultHTTPErrorHandler(exposeError bool) HTTPErrorHandler`
+
+### 4. HTTPError: message is string
+
+v4: `NewHTTPError(code int, message ...interface{})` - message is `interface{}`
+v5: `NewHTTPError(code int, message string)` - message is `string`
+
+Added `HTTPError.Wrap(err error)` and `HTTPError.StatusCode()` methods.
+
+### 5. Router: interface introduced
+
+v4: `func NewRouter(e *Echo) *Router` / `func (e *Echo) Router() *Router`
+v5: `func NewRouter(config RouterConfig) *DefaultRouter` / `func (e *Echo) Router() Router` (returns interface)
+
+New `Router` interface with `DefaultRouter` implementation. `NewConcurrentRouter(r Router) Router` for thread-safe routing.
+
+### 6. Route return types
+
+v4: `e.GET(...)` returns `*Route`, `e.Any(...)` returns `[]*Route`, `e.Routes()` returns `[]*Route`
+v5: `e.GET(...)` returns `RouteInfo`, `e.Any(...)` returns `RouteInfo`, new `Routes` type (`[]RouteInfo`) with filtering methods
+
+```go
+type RouteInfo struct {
+    Name       string
+    Method     string
+    Path       string
+    Parameters []string
+}
+```
+
+`Routes` has `FilterByMethod`, `FilterByName`, `FilterByPath`, `FindByMethodPath`, `Reverse` methods.
+
+### 7. Response type
+
+v4: `c.Response()` returns `*Response`
+v5: `c.Response()` returns `http.ResponseWriter`
+
+`Response` struct now embeds `http.ResponseWriter`. `NewResponse` takes `*slog.Logger` instead of `*Echo`.
+
+### 8. FormParam renamed to FormValue
+
+v4: `echo.FormParam[T](c Context, key string, ...)` / `FormParamOr` / `FormParams` / `FormParamsOr`
+v5: `echo.FormValue[T](c *Context, key string, ...)` / `FormValueOr` / `FormValues` / `FormValuesOr`
+
+### 9. Removed from Echo struct
+
+`StdLogger`, `Server`, `TLSServer`, `Listener`, `TLSListener`, `AutoTLSManager`, `ListenerNetwork`, `DisableHTTP2`, `Debug`, `HideBanner`, `HidePort` are all removed. Use `StartConfig` for server configuration.
+
+### 10. PathParams -> PathValues
+
+v4: `ParamNames()`, `ParamValues()`, `SetParamNames()`, `SetParamValues()`
+v5: `PathValues()` returns `PathValues` type (`[]PathValue`), `SetPathValues(PathValues)`
+
+### 11. Other renames
+
+- `PathParamsBinder` -> `PathValuesBinder`

 Key facts for LLMs:

-- Handlers use `*echo.Context` (pointer to struct), NOT `echo.Context` (interface) like v4
-- `Context` is a concrete struct in v5, not an interface
-- Logging uses `log/slog`, not the old custom `Logger` interface

 Import path: `github.com/labstack/echo/v5`
 Go version: 1.25+
 Handler signature: `func(c *echo.Context) error`
 
-## Critical v5 Breaking Changes
+## Context
 
-### 1. Context: interface to struct
+`Context` is a concrete struct passed by pointer to all handlers.
 
-v4: `type Context interface` with handler `func(c echo.Context) error`
-v5: `type Context struct` with handler `func(c *echo.Context) error`
-
-ALL handlers must use `*echo.Context` (pointer). The `Context` type is no longer an interface.
+```go
+type Context struct { ... }
 
-### 2. Logger: custom interface to slog
+// Handlers receive *echo.Context
+func handler(c *echo.Context) error { ... }
+```
 
-v4: `e.Logger` is a custom `Logger` interface with `Print`, `Debug`, `Info`, etc.
-v5: `e.Logger` is `*slog.Logger` from the standard library `log/slog` package.
+### Context methods
 
 ```go
-e.Logger = slog.Default()
-c.Logger().Info("message", "key", "value")
+c.Request() *http.Request
+c.SetRequest(r *http.Request)
+c.Response() http.ResponseWriter
+c.SetResponse(rw http.ResponseWriter)
+c.IsTLS() bool
+c.IsWebSocket() bool
+c.Scheme() string
+c.RealIP() string
+c.Path() string
+c.SetPath(path string)
+c.RouteInfo() RouteInfo
+c.Param(name string) string
+c.ParamOr(name, defaultValue string) string
+c.PathValues() PathValues
+c.SetPathValues(pathValues PathValues)
+c.QueryParam(name string) string
+c.QueryParamOr(name, defaultValue string) string
+c.QueryParams() []string
+c.QueryString() string
+c.FormValue(name string) string
+c.FormValueOr(name, defaultValue string) string
+c.FormValues() []string
+c.FormFile(name string) (*multipart.FileHeader, error)
+c.MultipartForm() (*multipart.Form, error)
+c.Cookie(name string) (*http.Cookie, error)
+c.SetCookie(cookie *http.Cookie)
+c.Cookies() []*http.Cookie
+c.Get(key string) any
+c.Set(key string, val any)
+c.Bind(i any) error
+c.Validate(i any) error
+c.Render(code int, name string, data any) error
+c.HTML(code int, html string) error
+c.HTMLBlob(code int, b []byte) error
+c.String(code int, s string) error
+c.JSON(code int, i any) error

+c.Attachment(file, name string) error
+c.Inline(file, name string) error
+c.NoContent(code int) error
+c.Redirect(code int, url string) error
+c.Logger() *slog.Logger
+c.SetLogger(logger *slog.Logger)
+c.Echo() *Echo
 ```
 
-### 3. HTTPErrorHandler: parameters swapped
-
-v4: `type HTTPErrorHandler func(err error, c Context)`
-v5: `type HTTPErrorHandler func(c *Context, err error)`
-
-`DefaultHTTPErrorHandler` is now a factory: `echo.DefaultHTTPErrorHandler(exposeError bool) HTTPErrorHandler`
-
-### 4. HTTPError: message is string
-
-v4: `NewHTTPError(code int, message ...interface{})` - message is `interface{}`
-v5: `NewHTTPError(code int, message string)` - message is `string`
-
-Added `HTTPError.Wrap(err error)` and `HTTPError.StatusCode()` methods.
-
-### 5. Router: interface introduced
-
-v4: `func NewRouter(e *Echo) *Router` / `func (e *Echo) Router() *Router`
-v5: `func NewRouter(config RouterConfig) *DefaultRouter` / `func (e *Echo) Router() Router` (returns interface)
-
-New `Router` interface with `DefaultRouter` implementation. `NewConcurrentRouter(r Router) Router` for thread-safe routing.
-
-### 6. Route return types
-
-v4: `e.GET(...)` returns `*Route`, `e.Any(...)` returns `[]*Route`, `e.Routes()` returns `[]*Route`
-v5: `e.GET(...)` returns `RouteInfo`, `e.Any(...)` returns `RouteInfo`, new `Routes` type (`[]RouteInfo`) with filtering methods
+### Context store (type-safe)
 
 ```go
-type RouteInfo struct {
-    Name       string
-    Method     string
-    Path       string
-    Parameters []string
-}
+c.Set("user", user)
+val, err := echo.ContextGet[*User](c, "user")
+count, err := echo.ContextGetOr[int](c, "count", 0)
 ```
 
-`Routes` has `FilterByMethod`, `FilterByName`, `FilterByPath`, `FindByMethodPath`, `Reverse` methods.
-
-### 7. Response type
-
-v4: `c.Response()` returns `*Response`
-v5: `c.Response()` returns `http.ResponseWriter`
-
-`Response` struct now embeds `http.ResponseWriter`. `NewResponse` takes `*slog.Logger` instead of `*Echo`.
-
-### 8. FormParam renamed to FormValue
-
-v4: `echo.FormParam[T](c Context, key string, ...)` / `FormParamOr` / `FormParams` / `FormParamsOr`
-v5: `echo.FormValue[T](c *Context, key string, ...)` / `FormValueOr` / `FormValues` / `FormValuesOr`
-
-### 9. Removed from Echo struct
-
-`StdLogger`, `Server`, `TLSServer`, `Listener`, `TLSListener`, `AutoTLSManager`, `ListenerNetwork`, `DisableHTTP2`, `Debug`, `HideBanner`, `HidePort` are all removed. Use `StartConfig` for server configuration.
-
-### 10. PathParams -> PathValues
-
-v4: `ParamNames()`, `ParamValues()`, `SetParamNames()`, `SetParamValues()`
-v5: `PathValues()` returns `PathValues` type (`[]PathValue`), `SetPathValues(PathValues)`
-
-### 11. Other renames
-
-- `PathParamsBinder` -> `PathValuesBinder`
-- `BindPathParams` -> `BindPathValues`
-- `Map` type removed (use `map[string]any`)
-- HTTP method constants removed (use `http.MethodGet`, etc.)
-- `GetPath(r *http.Request)` removed (use `r.URL.Path`)

Subject: [PATCH 364/371] fix(middleware): match gzip Content-Encoding
 case-insensitively (#3056)

* fix(middleware): match gzip Content-Encoding case-insensitively

Proxies and clients may send Content-Encoding: Gzip or GZIP. Exact string
compare skipped decompression. Trim and EqualFold against "gzip".

* fix(middleware): keep gzip match to EqualFold only

Drop TrimSpace so the change is strictly RFC 9110 case-insensitivity
for content codings, per review discussion.

Subject: [PATCH 365/371] fix: resolve RealIP for bare RemoteAddr without port
 (#3054)

RealIP and LegacyIPExtractor discarded the address when net.SplitHostPort
failed (e.g. bare IPv4/IPv6 without :port). Reuse extractIP so behavior
matches ExtractIPDirect.

Subject: [PATCH 367/371] docs(middleware): clarify MethodOverrideGetter return
 value (#3059)

* fix(middleware): normalize MethodOverride method to uppercase

Overridden methods such as "delete" did not match router http.Method*
constants. Trim and uppercase the override value before assigning.

* docs(middleware): clarify MethodOverrideGetter return value

Per review: do not normalize override methods in middleware. Document that
Getter should return a standard method name (e.g. http.MethodDelete).

Subject: [PATCH 369/371] feat: add RFC 9457 Problem Details HTTP error handler
 (#3062)

Adds ProblemError (RFC 9457 fields), a ProblemErrorer interface so
custom error types can convert themselves to a ProblemError, and a
standalone ProblemDetailsHTTPErrorHandler that renders errors as
application/problem+json, as discussed in #3053.

Subject: [PATCH 370/371] docs: warn that predefined errors are no longer
 *HTTPError in v5 (#3063)

A v4-style custom HTTPErrorHandler that type-asserts err.(*echo.HTTPError)
silently stops matching the router's predefined errors (echo.ErrNotFound,
echo.ErrMethodNotAllowed, ...) in v5, because they are now immutable
sentinels implementing only HTTPStatusCoder. The result is every unmatched
route being rendered as a 500 instead of a 404, with no compile-time or
runtime signal.

Document the trap in the HTTPError section and the migration guide's error
handler step, pointing at echo.StatusCode(err) as the correct replacement.

+**⚠️ Migration trap:** predefined errors such as `echo.ErrNotFound` and
+`echo.ErrMethodNotAllowed` (returned by the router for unmatched routes) are no
+longer `*echo.HTTPError`. They are immutable sentinels that only implement
+`HTTPStatusCoder`, so a v4-style type assertion in a custom error handler stops
+matching them and turns every 404/405 into a 500:

+// Broken in v5: never matches echo.ErrNotFound
+if he, ok := err.(*echo.HTTPError); ok {
+    code = he.Code
+} else {
+    code = http.StatusInternalServerError

+// Correct: works for *HTTPError and the predefined errors

Subject: [PATCH 371/371] fix(middleware): classify CORS preflight per Fetch
 standard (#3060)

Only OPTIONS requests that include both Origin and
Access-Control-Request-Method are treated as CORS preflights.

Previously every OPTIONS request was short-circuited, so non-CORS
OPTIONS handlers (and OPTIONS without ACR-Method) never ran (#2534).
