+## [Unreleased]
+
+## [1.17.0] - 2026-08-11
+### Added
+- Added support for using multiple glossaries in text and document translation
+  via `setGlossaryIds()`/`setGlossaries()` (up to 5 glossaries) in
+  `TextTranslationOptions` and `DocumentTranslationOptions`.
+- Added support for style rules in document translation via
+  `setStyleRule()`/`setStyleId()` in `DocumentTranslationOptions`.
+- Added support for translation memories in document translation via
+  `setTranslationMemory()`/`setTranslationMemoryId()`/`setTranslationMemoryThreshold()`
+  in `DocumentTranslationOptions`.
+- Added support for the translation memory management endpoints in the
+  `DeepLClient` class: `getTranslationMemory()`,
+  `listTranslationMemorySegments()`, `deleteTranslationMemory()`,
+  `createTranslationMemoryImport()`, `uploadTranslationMemoryFile()`,
+  `createTranslationMemoryExport()`, `getTranslationMemoryJob()`,
+  `waitUntilTranslationMemoryJobDone()`, `downloadTranslationMemoryExport()`,
+  `importTranslationMemoryFromFilepath()` and
+  `exportTranslationMemoryToFilepath()`.
+- Added `creationTime` and `updatedTime` to `TranslationMemoryInfo`.
+- Added optional timeouts to `waitUntilTranslationMemoryJobDone()`,
+  `importTranslationMemoryFromFilepath()` and
+  `exportTranslationMemoryToFilepath()`.
 
-## Unreleased
 ### Fixed
-* Change document upload to use the path `/v2/document` instead of `/v2/document/` (no trailing `/`).
-  Both paths will continue to work in the v2 version of the API, but `/v2/document` is the intended one.
+- Fixed `waitUntilTranslationMemoryJobDone()` throwing when a translation memory
+  job reports `AwaitingInput`. An import job keeps reporting that status for a
+  while after its file has been uploaded, because the API detects the upload
+  asynchronously, so it is now polled through like any other non-terminal
+  status.
+- Fixed incorrect example texts in the test suite for several languages (Danish,
+  Indonesian, Japanese, Portuguese, and Russian) to match the mock server.
 
+## [1.16.0] - 2026-04-09
+### Added
+- Added support for translation memories in text translation via
+  `setTranslationMemoryId()` and `setTranslationMemoryThreshold()` in
+  `TextTranslationOptions`.
+- Added `listTranslationMemories()` method to the `DeepLClient` class for
+  listing available translation memories.
 
-## [1.4.0] - 2023-11-03
+### Fixed
+- Fixed GitLab release job using wrong image by explicitly setting `image: registry.gitlab.com/gitlab-org/release-cli:latest`.
+
+## [1.15.0] - 2026-03-26
 ### Added
-* Add optional `context` parameter for text translation, that specifies
-  additional context to influence translations, that is not translated itself.
+- Added JSON request body support to `HttpContent` and `HttpClientWrapper`, enabling
+  JSON-encoded API calls via `sendJsonRequestWithBackoff()` and `sendJsonPatchRequestWithBackoff()`.
+- Added support for style rules CRUD endpoints in the `DeepLClient` class:
+  `createStyleRule()`, `getStyleRule()`, `updateStyleRuleName()`,
+  `updateStyleRuleConfiguredRules()`, and `deleteStyleRule()`.
+- Added support for style rule custom instruction CRUD endpoints in the
+  `DeepLClient` class: `createStyleRuleCustomInstruction()`,
+  `getStyleRuleCustomInstruction()`, `updateStyleRuleCustomInstruction()`,
+  and `deleteStyleRuleCustomInstruction()`.
+  Please refer to the README for usage instructions.
+
+### Changed
+- Updated formality tests to accept either formal or informal output when using default formality,
+  since the default formality is automatic.
+- Updated `testModelType()` to just check if the `model_type_used` is non-null if the `model_type` is specified in the request
+- Updated `testMixedDirectionText()` to add a missing `</p>` tag
+- Improved `NotFoundException` error message by removing the misleading "check server_url" suggestion.
+
 ### Fixed
-* Remove unused `commons-math` dependency
+- Fixed PATCH requests (`sendPatchRequestWithBackoff`) not retrying on 429/5xx errors despite
+  the method name promising backoff behavior. PATCH requests now use the same retry logic as all
+  other HTTP methods.
+
+## [1.14.0] - 2025-12-10
+### Added
+- Added `setTagHandlingVersion()` method to `TextTranslationOptions` to specify which version of the tag handling algorithm to use. Options are `v1` and `v2`.
 
+## [1.13.0] - 2025-12-03
+### Added
+- Added `setCustomInstructions()` method to `TextTranslationOptions` to
+  customize translation behavior with up to 10 instructions (max 300 characters
+  each). Only supported for target languages: `de`, `en`, `es`, `fr`, `it`,
+  `ja`, `ko`, `zh` and their variants.
+
+  Note: using the custom instructions parameter will use `quality_optimized`
+  model type as the default. Requests combining custom instructions and the
+  `latency_optimized` model type will be rejected.
+
+## [1.12.0] - 2025-11-12
+### Added
+- Added support for the `GET /v3/style_rules` endpoint in the client library, the
+  implementation can be found in the `DeepLClient` class. Please refer to the
+  README for usage instructions
+- Added `styleId` option to `translateText()` which allows text translation with
+  style rules.
 
-## [1.3.0] - 2023-06-09 
+## [1.11.0] - 2025-11-04
+### Added
+- Added `extraRequestParameters` option to text and document translation methods to pass arbitrary parameters in the request body. This can be used to access beta features or override built-in parameters (such as `target_lang`, `source_lang`, etc.).
+
+## [1.10.3] - 2025-08-22
+### Security
+- Updated `org.apache.httpcomponents:httpclient` to 4.5.14 due to [CVE-2020-13956](https://nvd.nist.gov/vuln/detail/CVE-2020-13956).
+   * Thanks to [warm-tune](https://github.com/warm-tune) for reporting in [#72](https://github.com/DeepLcom/deepl-java/issues/72).
+
+## [1.10.2] - 2025-07-11
+### Changed
+- Migrate to Sonatype Portal OSSRH Staging API due to legacy OSSRH being sunsetted.
+- Whitespace surrounding auth key is now stripped.
+  * Thanks to [timazhum](https://github.com/timazhum) for the fix in [#64](https://github.com/DeepLcom/deepl-java/pull/69).
+
+## [1.10.1] - 2025-06-18
 ### Fixed
-* Changed document translation to poll the server every 5 seconds. This should greatly reduce observed document translation processing time.
-* Fix getUsage request to be a HTTP GET request, not POST.
+- Fixed `DeepLClient::deleteMultilingualGlossary(String glossaryId)` being package private, made it public instead.
+  * Thanks to [MTSxoff](https://github.com/MTSxoff) for the report in [#68](https://github.com/DeepLcom/deepl-java/issues/68) and the fix in [#69](https://github.com/DeepLcom/deepl-java/pull/69).
 
+## [1.10.0] - 2025-04-30
+### Added
+- Added support for the /v3 Multilingual Glossary APIs in the client library
+  while providing backwards compatability for the previous /v2 Glossary
+  endpoints. Please refer to the README or
+  [upgrading_to_multilingual_glossaries.md](upgrading_to_multilingual_glossaries.md)
+  for usage instructions.
+- Added Ukrainian language code
 
-## [1.2.0] - 2023-03-22
+## [1.9.0] - 2025-02-21
+### Added
+- Allow specifying the API version to use. This is mostly for users who have an
+  API subscription that includes an API key for CAT tool usage, who need to use
+  the v1 API.
+
+## [1.8.1] - 2025-02-07
+### Fixed
+- Added a constructor for `DeepLClient` that only takes an `authKey`, to fix the
+  README example and be in line with `Translator`.
+- Un-deprecated the `Translator` and `TranslatorOptions` class and moved it to
+  their constructors. The functionality in them continues to work and be supported,
+  user code should just use `DeepLClient` and `DeepLClientOptions`.
+
+## [1.8.0] - 2025-01-17
+### Added
+- Added support for the Write API in the client library, the implementation
+  can be found in the `DeepLClient` class. Please refer to the README for usage
+  instructions.
+
+### Changed
+- The main functionality of the library is now also exposed via the `DeepLClient`
+  class. Please change your code to use this over the `Translator` class whenever
+  convenient.
+
+## [1.7.0] - 2024-11-15
+### Added
+- Added `modelType` option to `translateText()` to use models with higher
+  translation quality (available for some language pairs), or better latency.
+  Options are `'quality_optimized'`, `'latency_optimized'`, and  `'prefer_quality_optimized'`
+- Added the `modelTypeUsed` field to `translateText()` response, that
+  indicates the translation model used when the `modelType` option is
+  specified.
+
+## [1.6.0] - 2024-09-17
+### Added
+- Added `getBilledCharacters()` to text translation response.
+
+## [1.5.1] - 2024-09-05
+### Fixed
+- Fixed parsing for usage count and limit for large values.

+## [1.5.0] - 2024-04-10
 ### Added
-* Script to check our source code for license headers and a step for them in the CI.
-* Added system and java version information to the user-agent string that is sent with API calls, along with an opt-out.
-* Added method for applications that use this library to identify themselves in API requests they make.
+- New language available: Arabic (MSA) (`'ar'`). Add language code constants and tests.
 
+  Note: older library versions also support the new language, this update only
+  adds new code constants.
+
+### Fixed
+- Change document upload to use the path `/v2/document` instead of `/v2/document/` (no trailing `/`).
+  Both paths will continue to work in the v2 version of the API, but `/v2/document` is the intended one.
+
+## [1.4.0] - 2023-11-03
+### Added
+- Add optional `context` parameter for text translation, that specifies
+  additional context to influence translations, that is not translated itself.

+### Fixed
+- Remove unused `commons-math` dependency
+
+## [1.3.0] - 2023-06-09
+### Fixed
+- Changed document translation to poll the server every 5 seconds. This should greatly reduce observed document translation processing time.

+### Improving text (Write API)
+
+You can use the Write API to improve or rephrase text. This is implemented in
+the `rephraseText()` method. The first argument is a string containing the text
+you want to translate, or a list of strings if you want to translate multiple texts.
+
+`targetLang` optionally specifies the target language, e.g. when you want to change
+the variant of a text (for example, you can send an english text to the write API and
+use `targetLang` to turn it into British or American English). Please note that the
+Write API itself does NOT translate. If you wish to translate and improve a text, you
+will need to make multiple calls in a chain.
+
+Language codes are the same as for translating text.
+
+Example call:
+
+```java
+WriteResult result = client.rephraseText("A rainbouw has seven colours.", "EN-US", null);
+System.out.println(result.getText);
+```
+
+Additionally, you can optionally specify a style OR a tone (not both at once) that the
+improvement should be in. The following styles are supported (`default` will be used if
+nothing is selected):
+
+- `academic`
+- `business`
+- `casual`
+- `default`
+- `simple`
+
+The following tones are supported (`default` will be used if nothing is selected):
+
+- `confident`
+- `default`
+- `diplomatic`
+- `enthusiastic`
+- `friendly`
+
+You can also prefix any non-default style or tone with `prefer_` (`prefer_academic`, etc.),
+in which case the style/tone will only be applied if the language supports it. If you do not
+use `prefer_`, requests with `targetLang`s or detected languages that do not support
+styles and tones will fail. The current list of supported languages can be found in our
+[API documentation][api-docs]. We plan to also expose this information via an API endpoint
+in the future.
+
+You can use the predefined constants in the library to use a style:
+
+```java
+TextRephraseOptions options = (new TextRephraseOptions()).setWritingStyle(WritingStyle.Business.getValue());
+WriteResult result = client.rephraseText("A rainbouw has seven colours.", "EN-US", options);

+### Style Rules
+
+Style rules allow you to customize your translations using a managed, shared list
+of rules for style, formatting, and more. Multiple style rules can be stored with
+your account, each with a user-specified name and a uniquely-assigned ID.
+
+#### Creating a style rule
+
+Use `createStyleRule()` to create a new style rule. You must specify a name and
+language code. You may optionally provide configured rules and custom
+instructions:
+
+```java
+class Example {  // Continuing class Example from above
+    public void createStyleRuleExample() throws Exception {
+        // Create a simple style rule
+        StyleRuleInfo rule = client.createStyleRule("My Style", "en", null, null);
+        System.out.println("Created: " + rule.getStyleId());
+
+        // Create with custom instructions
+        List<CustomInstruction> instructions = new ArrayList<>();
+        instructions.add(new CustomInstruction("Formal tone", "Use formal language", null));
+        StyleRuleInfo ruleWithInstructions = client.createStyleRule(
+            "Formal Style", "en", null, instructions);
+    }
+}
+```
+
+#### Retrieving and listing style rules
+
+`getStyleRule()` retrieves a single style rule by its ID. `getAllStyleRules()`
+returns a list of `StyleRuleInfo` objects corresponding to all of your stored
+style rules. The method accepts optional parameters: `page` (page number for
+pagination, 0-indexed), `pageSize` (number of items per page), and `detailed`.
+When `true`, the response includes `configuredRules` and `customInstructions`
+for each style rule. When `false` (default), these fields are omitted for faster
+responses.
+
+```java
+class Example {  // Continuing class Example from above
+    public void listStyleRulesExample() throws Exception {
+        // Get a single style rule by ID
+        StyleRuleInfo rule = client.getStyleRule("dca2e053-8ae5-45e6-a0d2-881156e7f4e4");
+        System.out.println(rule.getName());
+
+        // Get all style rules
+        List<StyleRuleInfo> styleRules = client.getAllStyleRules();
+        for (StyleRuleInfo r : styleRules) {
+            System.out.println(String.format("%s (%s)", r.getName(), r.getStyleId()));
+        }
+
+        // Get style rules with detailed configuration
+        List<StyleRuleInfo> styleRulesDetailed = client.getAllStyleRules(null, null, true);
+        for (StyleRuleInfo r : styleRulesDetailed) {
+            if (r.getConfiguredRules() != null && r.getConfiguredRules().getNumbers() != null) {
+                System.out.println(String.format("Number formatting rules: %s",
+                    String.join(", ", r.getConfiguredRules().getNumbers().keySet())));
+            }
+        }
+    }
+}
+```
+
+#### Updating a style rule
+
+Use `updateStyleRuleName()` to rename a style rule, and
+`updateStyleRuleConfiguredRules()` to replace its configured rules:
+
+```java
+class Example {  // Continuing class Example from above
+    public void updateStyleRuleExample() throws Exception {
+        String styleId = "dca2e053-8ae5-45e6-a0d2-881156e7f4e4";
+
+        // Update the name
+        StyleRuleInfo updated = client.updateStyleRuleName(styleId, "New Name");
+        System.out.println("Updated name: " + updated.getName());
+
+        // Update configured rules
+        ConfiguredRules configuredRules = new ConfiguredRules();
+        StyleRuleInfo updatedRules = client.updateStyleRuleConfiguredRules(
+            styleId, configuredRules);
+    }
+}
+```
+
+#### Managing custom instructions
+
+Custom instructions can be created, retrieved, updated, and deleted individually
+within a style rule:
+
+```java
+class Example {  // Continuing class Example from above
+    public void customInstructionsExample() throws Exception {
+        String styleId = "dca2e053-8ae5-45e6-a0d2-881156e7f4e4";
+
+        // Create a custom instruction
+        CustomInstruction instruction = client.createStyleRuleCustomInstruction(
+            styleId, "Formal tone", "Always use formal language", null);
+        String instructionId = instruction.getId();
+
+        // Retrieve the custom instruction
+        CustomInstruction retrieved = client.getStyleRuleCustomInstruction(
+            styleId, instructionId);
+        System.out.println(retrieved.getLabel());
+
+        // Update the custom instruction
+        CustomInstruction updated = client.updateStyleRuleCustomInstruction(
+            styleId, instructionId, "Updated label", "Updated prompt", null);
+
+        // Delete the custom instruction
+        client.deleteStyleRuleCustomInstruction(styleId, instructionId);
+    }
+}
+```
+
+#### Deleting a style rule
+
+Use `deleteStyleRule()` to permanently remove a style rule from your account:
+
+```java
+class Example {  // Continuing class Example from above
+    public void deleteStyleRuleExample() throws Exception {
+        client.deleteStyleRule("dca2e053-8ae5-45e6-a0d2-881156e7f4e4");
+    }
+}
+```
+
+#### Using a stored style rule in translations
+
+You can use a stored style rule for text translation by setting the `styleRule`
+argument to either the style rule ID or `StyleRuleInfo` object:
+
+```java
+class Example {  // Continuing class Example from above
+    public void usingStyleRuleExample() throws Exception {
+        String styleId = "dca2e053-8ae5-45e6-a0d2-881156e7f4e4";
+        TextResult result = client.translateText(
+            "Hallo, Welt!",
+            "de",
+            "en-US",
+            new TextTranslationOptions().setStyleId(styleId));
+        System.out.println(result.getText());
+    }
+}
+```
+
+### Translation Memories
+
+Translation memories store and reuse previously created translations, helping to
+ensure consistency and reduce effort when translating similar or repeated content.
+
+#### Listing translation memories
+
+Use `listTranslationMemories()` to retrieve translation memories associated
+with your account. The number of translation memories returned is controlled by
+`pageSize` (max 25). The method accepts optional parameters: `page` (page number
+for pagination, 0-indexed) and `pageSize` (number of items per page).
+
+```java
+class Example {  // Continuing class Example from above
+    public void listTranslationMemoriesExample() throws Exception {
+        List<TranslationMemoryInfo> translationMemories =
+                client.listTranslationMemories();
+        for (TranslationMemoryInfo tm : translationMemories) {
+            System.out.println(String.format("%s (%s)",
+                tm.getName(), tm.getTranslationMemoryId()));
+        }
+    }
+}
+```
+
+#### Retrieving a translation memory
+
+Use `getTranslationMemory()` to retrieve a single translation memory. It accepts
+either a translation memory ID or a `TranslationMemoryInfo` object:
+
+```java
+class Example {  // Continuing class Example from above
+    public void getTranslationMemoryExample() throws Exception {
+        TranslationMemoryInfo tm = client.getTranslationMemory("YOUR_TM_ID");
+        System.out.println(String.format("%s: %d segments, updated %s",
+            tm.getName(), tm.getSegmentCount(), tm.getUpdatedTime()));
+    }
+}
+```
+
+#### Listing the segments of a translation memory
+
+`listTranslationMemorySegments()` returns one page of segments as a
+`TranslationMemorySegments` object. Pagination is cursor-based: omit the page
+cursor on the first call, then pass the previous response's
+`getNextPageCursor()` until it is `null`. Optionally filter with `setFilterText()`
+(at least 2 characters, matched against both source and target text) and
+`setFilterCaseSensitive()`. Note that `getSegmentCount()` is the
+translation-memory total and is not reduced by the filter. The API may omit the
+segment timestamps, in which case `getCreationTime()`, `getUpdatedTime()` and
+`getLastUsedTime()` are `null` on both segments and their targets.
+
+```java
+class Example {  // Continuing class Example from above
+    public void listTranslationMemorySegmentsExample() throws Exception {
+        String pageCursor = null;

+                "YOUR_TM_ID",
+                new TranslationMemorySegmentsOptions()
+                    .setPageSize(50)

+        } while (pageCursor != null);
+    }
+}
+```
+
+#### Importing a translation memory
+
+`importTranslationMemoryFromFilepath()` imports a TMX file as a new translation
+memory: it creates the import job, uploads the file, and waits for processing to
+finish. The returned `TranslationMemoryJob` carries the ID of the new translation
+memory:
+
+```java
+class Example {  // Continuing class Example from above
+    public void importTranslationMemoryExample() throws Exception {
+        TranslationMemoryJob job = client.importTranslationMemoryFromFilepath(
+            new File("/path/to/legal.tmx"), "Legal TM", Duration.ofSeconds(300));
+        System.out.println(String.format("Created translation memory %s",
+            job.getResult().getTranslationMemoryId()));
+        System.out.println(String.format("Skipped segments: %s",
+            job.getResult().getSkippedSegmentCount()));
+    }
+}
+```
+
+The optional timeout is the maximum time to wait for the import to finish; omit
+it to wait indefinitely. The job status is polled every 5 seconds, so the
+timeout is not accurate to the millisecond.
+
+The three steps are also available separately, for example to upload the file
+yourself or to poll for progress. `createTranslationMemoryImport()` returns an
+upload URL that the file must be uploaded to before processing starts, then
+`getTranslationMemoryJob()` reports the status:
+
+```java
+class Example {  // Continuing class Example from above
+    public void importTranslationMemoryStepsExample() throws Exception {
+        File inputFile = new File("/path/to/legal.tmx");
+        byte[] fileContent = Files.readAllBytes(inputFile.toPath());
+
+        TranslationMemoryImport created = client.createTranslationMemoryImport(
+            inputFile.getName(), fileContent.length, null, "Legal TM");
+        // Until the file is uploaded, the job status is AwaitingInput
+        client.uploadTranslationMemoryFile(created, fileContent);
+
+        TranslationMemoryJob job = client.waitUntilTranslationMemoryJobDone(
+            created.getJobId(), Duration.ofSeconds(300));
+    }
+}
+```
+
+Note that an import job keeps reporting `AwaitingInput` for a while after its
+file has been uploaded, because the API detects the upload asynchronously.
+`waitUntilTranslationMemoryJobDone()` polls through that status like any other
+non-terminal one. A job whose file is never uploaded does not finish on its own,
+so pass a timeout when that is a possibility.
+
+#### Exporting a translation memory
+
+`exportTranslationMemoryToFilepath()` exports a translation memory to a TMX file:
+it creates the export job, waits for it to finish, and writes the result. It
+accepts either a translation memory ID or a `TranslationMemoryInfo` object:
+
+```java
+class Example {  // Continuing class Example from above
+    public void exportTranslationMemoryExample() throws Exception {
+        TranslationMemoryJob job = client.exportTranslationMemoryToFilepath(
+            "YOUR_TM_ID", new File("/path/to/exported.tmx"), Duration.ofSeconds(300));
+    }
+}
+```
+
+As with import, the timeout is optional; omit it to wait indefinitely.
+
+As with import, the individual steps are available separately. Note that the API
+may reuse a previously completed export of an unchanged translation memory,
+indicated by `isReusedExisting()`:
+
+```java
+class Example {  // Continuing class Example from above
+    public void exportTranslationMemoryStepsExample() throws Exception {
+        TranslationMemoryExport created =
+            client.createTranslationMemoryExport("YOUR_TM_ID");
+        TranslationMemoryJob job =
+            client.waitUntilTranslationMemoryJobDone(created.getJobId());
+        client.downloadTranslationMemoryExport(
+            job, new File("/path/to/exported.tmx"));
+    }
+}
+```
+
+#### Deleting a translation memory
+
+Use `deleteTranslationMemory()` to permanently remove a translation memory from
+your account. It accepts either a translation memory ID or a
+`TranslationMemoryInfo` object:
+
+```java
+class Example {  // Continuing class Example from above
+    public void deleteTranslationMemoryExample() throws Exception {
+        client.deleteTranslationMemory("YOUR_TM_ID");
+    }
+}
+```
+
+#### Using a translation memory in translations
+
+You can use a translation memory for text translation by setting the translation
+memory options in `TextTranslationOptions`:
+
+```java
+class Example {  // Continuing class Example from above
+    public void usingTranslationMemoryExample() throws Exception {
+        // Using the translation memory ID directly
+        TextTranslationOptions options = new TextTranslationOptions()
+                .setTranslationMemoryId("tm-123abc")
+                .setTranslationMemoryThreshold(80);
+        TextResult result = client.translateText(
+            "Hello, world!", null, "de", options);
+        System.out.println(result.getText());
+
+        // Or using a TranslationMemoryInfo object from listTranslationMemories()
+        List<TranslationMemoryInfo> memories = client.listTranslationMemories();
+        if (!memories.isEmpty()) {
+            TextTranslationOptions optionsFromInfo = new TextTranslationOptions()
+                    .setTranslationMemory(memories.get(0));
+            TextResult resultFromInfo = client.translateText(
+                "Hello, world!", null, "de", optionsFromInfo);
+            System.out.println(resultFromInfo.getText());
+        }

+# Migration Documentation for Newest Glossary Functionality
+
+## 1. Overview of Changes
+
+The newest version of the Glossary APIs is the `/v3` endpoints, which introduce enhanced functionality:
+
+- **Support for Multilingual Glossaries**: The v3 endpoints allow for the creation of glossaries with multiple language
+  pairs, enhancing flexibility and usability.
+- **Editing Capabilities**: Users can now edit existing glossaries.
+
+To support these new v3 APIs, we have created new methods to interact with these new multilingual glossaries. Users are
+encouraged to transition to the new to take full advantage of these new features. However, for those who prefer to
+continue using the existing functionality, the `v2` methods for monolingual glossaries (e.g., `createGlossary()`,
+`getGlossary()`, etc.) remain available.
+
+## 2. Endpoint Changes
+
+| Monolingual glossary methods   | Multilingual glossary methods                | Changes Summary                                                                                                                                                                      |
+|--------------------------------|----------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| `createGlossary()`        | `createMultilingualGlossary()`          | Accepts a list of `MultilingualGlossaryDictionaryEntries` for multi-lingual support and now returns a `MultilingualGlossaryInfo` object.                                             |
+| `createGlossaryFromCsv()` | `createMultilingualGlossaryFromCsv()`   | Similar functionality, but now returns a `MultilingualGlossaryInfo` object                                                                                                           |
+| `getGlossary()`           | `getMultilingualGlossary()`             | Similar functionality, but now returns `MultilingualGlossaryInfo`. Also can accept a `MultilingualGlossaryInfo` object as the glossary parameter instead of a `GlossaryInfo` object. |

+
+## 3. Model Changes
+
+V2 glossaries are monolingual and the previous glossary objects could only have entries for one language pair (
+`SourceLanguageCode` and `TargetLanguageCode`). Now we introduce the concept of "glossary dictionaries", where a
+glossary dictionary specifies its own `SourceLanguageCode`, `TargetLanguageCode`, and has its own entries.
+
+- **Glossary Information**:
+  - **v2**: `GlossaryInfo` supports only mono-lingual glossaries, containing fields such as `SourceLanguageCode`,
+    `TargetLanguageCode`, and `EntryCount`.
+  - **v3**: `MultilingualGlossaryInfo` supports multi-lingual glossaries and includes a list of
+    `MultilingualGlossaryDictionaryInfo`, which provides details about each glossary dictionary, each with its own
+    `SourceLanguageCode`, `TargetLanguageCode`, and `EntryCount`.
+
+- **Glossary Entries**:
+  - **v3**: Introduces `MultilingualGlossaryDictionaryEntries`, which encapsulates a glossary dictionary with source and
+    target languages along with its entries.
+
+## 4. Code Examples
+
+### Create a glossary
+
+```java
+class Example {
