• Fix an issue that first appeared in CodeQL Action v2.21.2 that prevented CodeQL invocations from being logged. #1833
• We are rolling out a feature in August 2023 that will improve the quality of file coverage information. #1835

2.21.1 - 26 Jul 2023

• Improve the handling of fatal errors from the CodeQL CLI. #1795
• Add the sarif-output output to the analyze action that contains the path to the directory of the generated SARIF. #1799

2.21.0 - 19 Jul 2023

• CodeQL Action now requires CodeQL CLI 2.9.4 or later. For more information, see the corresponding changelog entry for CodeQL Action version 2.20.4. #1724

2.20.4 - 14 Jul 2023

• This is the last release of the Action that supports CodeQL CLI versions 2.8.5 to 2.9.3. These versions of the CodeQL CLI were deprecated on June 20, 2023 alongside GitHub Enterprise Server 3.5 and will not be supported by the next release of the CodeQL Action (2.21.0).
  • If you are using one of these versions, please update to CodeQL CLI version 2.9.4 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 2.8.5 and 2.9.3, you can replace 'github/codeql-action/@ v2' by 'github/codeql-action/@ v2.20.4' in your code scanning workflow to ensure you continue using this version of the CodeQL Action.
• We are rolling out a feature in July 2023 that will slightly reduce the default amount of RAM used for query execution, in proportion to the runner's total memory. This will help to avoid out-of-memory failures on larger runners. #1760
• Update default CodeQL bundle version to 2.14.0. #1762
