 - Update default CodeQL bundle version to 2.14.3. [#1845](https://github.com/github/codeql-action/pull/1845)
 - Fixed a bug in CodeQL Action 2.21.3 onwards that affected beta support for [Project Lombok](https://projectlombok.org/) when analyzing Java. The environment variable `CODEQL_EXTRACTOR_JAVA_RUN_ANNOTATION_PROCESSORS` will now be respected if it was manually configured in the workflow. [#1844](https://github.com/github/codeql-action/pull/1844)
 - Enable support for Kotlin 1.9.20 when running with CodeQL CLI v2.13.4 through v2.14.3. [#1853](https://github.com/github/codeql-action/pull/1853)
