Full Changelog: v9.0.4...v10.0.0

Fixed

• Initial config JSON load when auto poll enabled with results from cache.

• Fix wrong JSON format handling during the evaluation process
• Add more Config V2 test cases
• Evaluation log fixes.

• Evaluation log fixes.
• Improve the message of log event 1103.
• Don't swallow, but log exceptions when config JSON reading fails so users know what went wrong with the parsing.
• LocalFileDataSource Unicode fix on Windows.
• User attribute value as string list support.

• Fix get_key_and_value() according to conifg_v6.json changes.

New features and improvements:

• Add support for the new Config JSON v6 format: update the config model and implement new features in setting evaluation logic.
• Overhaul setting evaluation-related logging and make it consistent across SDKs.
• Performance improvements to setting evaluation when info level logging is turned off.
• Python 3.12 support

Breaking changes:

• The User's custom dictionary also allows attribute values other than string values.
• The config JSON v5 format is no longer accepted by flag overrides. If you use this feature, you will need to convert your override JSON file(s) to the v6 format. You can do this using the config-json convert v5-to-v6 command of the ConfigCat CLI tool.
• Rename the matched_evaluation_percentage_rule property to matched_targeting_rule and the matched_evaluation_rule`` property to matched_percentage_optioninEvaluationDetails`.
• Throw ConfigCatClientException when the SDK key passed to ConfigCatClient.get is in an invalid format (unless the client is set up to use local-only flag override behaviour).

For Python version >= 3.7 increase minimum version of requests dependency to 2.31.0.

Please note that this version has several breaking changes, so you may need to adjust your code when upgrading, especially if you're using deprecated APIs or a custom cache implementation. You can find the detailed list of breaking changes below.

• Removed unsupported Python versions: 2.6, 3.3, 3.4.
• Added Python 3.11 support.
• Removed deprecated init functions: configcatclient.create_client, configcatclient.create_client_with_auto_poll, configcatclient.create_client_with_lazy_load, configcatclient.create_client_with_manual_poll. Create the ConfigCat Client as a Singleton object with configcatclient.get() instead.
• Updated logging:
  • Include event IDs in log messages to make identification of log events easier.
  • Revise log messages and make them consistent across the ConfigCat SDKs.
• Revise caching of downloaded config data:
  • Use a standardized config cache key generation algorithm and cache payload format to allow shared caches to be used by SDKs of different platforms.
• Updated semver dependency >=2.10.2.

• Add 3.7, 3.8, 3.9, 3.10 to supported python versions in setup.py.
• Don't start polling in offline mode when init ConfigService.
• Use empty etag for empty ConfigEntry object.
