CodeQL Action Changelog

See the releases page for the relevant changes to the CodeQL CLI and language packs.

[UNRELEASED]

• Add a workaround python 3.12, which is not supported in CodeQL CLI version 2.14.6 or earlier. If you are running an analysis on Windows and using python 3.12 or later, the CodeQL Action will switch to running python 3.11. If python 3.11 is not found, then the workflow will fail.

2.22.0 - 06 Oct 2023

• The CodeQL Action now requires CodeQL version 2.10.5 or later. For more information, see the corresponding changelog entry for CodeQL Action version 2.21.8. #1907
• The CodeQL Action no longer runs ML-powered queries. For more information, including details on our investment in AI-powered security technology, see "CodeQL code scanning deprecates ML-powered alerts." #1910
• Fix a bug which prevented tracing of projects using Go 1.21 and above on Linux. #1909

2.21.9 - 27 Sep 2023

• Update default CodeQL bundle version to 2.14.6. #1897
• We are rolling out a feature in October 2023 that will improve the success rate of C/C++ autobuild. #1889
• We are rolling out a feature in October 2023 that will provide specific file coverage information for C and C++, Java and Kotlin, and JavaScript and TypeScript. Currently file coverage information for each of these pairs of languages is grouped together. #1903
• Add a warning to help customers avoid inadvertently analyzing the same CodeQL language in multiple matrix jobs. #1901

2.21.8 - 19 Sep 2023

• Add a deprecation warning for customers using CodeQL version 2.10.4 and earlier. These versions of CodeQL were discontinued on 12 September 2023 alongside GitHub Enterprise Server 3.6, and will be unsupported by the next minor release of the CodeQL Action. #1884
  • If you are using one of these versions, please update to CodeQL CLI version 2.10.5 or later. For instance, if you have specified a custom version of the CLI using the 'tools' input to the 'init' Action, you can remove this input to use the default version.
  • Alternatively, if you want to continue using a version of the CodeQL CLI between 2.9.5 and 2.10.4, you can replace github/codeql-action/*@v2 by github/codeql-action/*@v2.21.7 in your code scanning workflow to ensure you continue using this version of the CodeQL Action.
• Enable the following language aliases when using CodeQL 2.14.4 and later: c-cpp for C/C++ analysis, java-kotlin for Java/Kotlin analysis, and javascript-typescript for JavaScript/TypeScript analysis. #1883

2.21.7 - 14 Sep 2023

• Update default CodeQL bundle version to 2.14.5. #1882

2.21.6 - 13 Sep 2023

• Better error message when there is a failure to determine the merge base of the code to analysis. #1860
• Improve the calculation of default amount of RAM used for query execution on GitHub Enterprise Server. This now reduces in proportion to the runner's total memory to better account for system memory usage, helping to avoid out-of-memory failures on larger runners. This feature is already available to GitHub.com users. #1866
• Enable improved file coverage information for GitHub Enterprise Server users. This feature is already available to GitHub.com users. #1867
• Update default CodeQL bundle version to 2.14.4. #1873

2.21.5 - 28 Aug 2023

• Update default CodeQL bundle version to 2.14.3. #1845
• Fixed a bug in CodeQL Action 2.21.3 onwards that affected beta support for Project Lombok 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
• Enable support for Kotlin 1.9.20 when running with CodeQL CLI v2.13.4 through v2.14.3. #1853

2.21.4 - 14 Aug 2023

• Update default CodeQL bundle version to 2.14.2. #1831
• Log a warning if the amount of available disk space runs low during a code scanning run. #1825
• When downloading CodeQL bundle version 2.13.4 and later, cache these bundles in the Actions tool cache using a simpler version number. #1832
