New features

• Java 21 is now fully supported, including support for new language features such as pattern switches and record patterns.

Improvements

• Parallelism in the evaluator has been improved, resulting in faster analysis when running with many threads, particularly for large databases.

For more information about the changes included in this release, see the CodeQL CLI changelog.

You can download either the codeql-PLATFORM.zip for your platform, or the generic codeql.zip which contains binaries for all supported platforms. Please ignore the additional "source code" downloads below the .zip artifacts.

This release is compatible with the CodeQL language packs from github/codeql@codeql-cli/v2.15.4.
