# CodeQL Action Changelog

See the [releases page](https://github.com/github/codeql-action/releases) for the relevant changes to the CodeQL CLI and language packs.

## [UNRELEASED]

No user facing changes.

## 4.36.2 - 04 Jun 2026

- Cache CodeQL CLI version information across Actions steps. [#3943](https://github.com/github/codeql-action/pull/3943)
- Reduce requests while waiting for analysis processing by using exponential backoff when polling SARIF processing status. [#3937](https://github.com/github/codeql-action/pull/3937)
- Update default CodeQL bundle version to [2.25.6](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.6). [#3948](https://github.com/github/codeql-action/pull/3948)

## 4.36.1 - 02 Jun 2026

No user facing changes.

## 4.36.0 - 22 May 2026

- _Breaking change_: Bump the minimum required CodeQL bundle version to 2.19.4. [#3894](https://github.com/github/codeql-action/pull/3894)
- Add support for SHA-256 Git object IDs. [#3893](https://github.com/github/codeql-action/pull/3893)
- Update default CodeQL bundle version to [2.25.5](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.5). [#3926](https://github.com/github/codeql-action/pull/3926)

## 4.35.5 - 15 May 2026

- We have improved how the JavaScript bundles for the CodeQL Action are generated to avoid duplication across bundles and reduce the size of the repository by around 70%. This should have no effect on the runtime behaviour of the CodeQL Action. [#3899](https://github.com/github/codeql-action/pull/3899)
- For performance and accuracy reasons, [improved incremental analysis](https://github.com/github/roadmap/issues/1158) will now only be enabled on a pull request when diff-informed analysis is also enabled for that run. If diff-informed analysis is unavailable (for example, because the PR diff ranges could not be computed), the action will fall back to a full analysis. [#3791](https://github.com/github/codeql-action/pull/3791)
- If multiple inputs are provided for the GitHub-internal `analysis-kinds` input, only `code-scanning` will be enabled. The `analysis-kinds` input is experimental, for GitHub-internal use only, and may change without notice at any time. [#3892](https://github.com/github/codeql-action/pull/3892)
- Added an experimental change which, when running a Code Scanning analysis for a PR with [improved incremental analysis](https://github.com/github/roadmap/issues/1158) enabled, prefers CodeQL CLI versions that have a cached overlay-base database for the configured languages. This speeds up analysis for a repository when there is not yet a cached overlay-base database for the latest CLI version. We expect to roll this change out to everyone in May. [#3880](https://github.com/github/codeql-action/pull/3880)

## 4.35.4 - 07 May 2026

- Update default CodeQL bundle version to [2.25.4](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4). [#3881](https://github.com/github/codeql-action/pull/3881)

## 4.35.3 - 01 May 2026

- _Upcoming breaking change_: Add a deprecation warning for customers using CodeQL version 2.19.3 and earlier. These versions of CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise Server 3.15, and will be unsupported by the next minor release of the CodeQL Action. [#3837](https://github.com/github/codeql-action/pull/3837)
- Configurations for private registries that use Cloudsmith or GCP OIDC are now accepted. [#3850](https://github.com/github/codeql-action/pull/3850)
- Best-effort connection tests for private registries now use `GET` requests instead of `HEAD` for better compatibility with various registry implementations. For NuGet feeds, the test is now always performed against the service index. [#3853](https://github.com/github/codeql-action/pull/3853)
- Fixed a bug where two diagnostics produced within the same millisecond could overwrite each other on disk, causing one of them to be lost. [#3852](https://github.com/github/codeql-action/pull/3852)
- Update default CodeQL bundle version to [2.25.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.3). [#3865](https://github.com/github/codeql-action/pull/3865)

## 4.35.2 - 15 Apr 2026

- The undocumented TRAP cache cleanup feature that could be enabled using the `CODEQL_ACTION_CLEANUP_TRAP_CACHES` environment variable is deprecated and will be removed in May 2026. If you are affected by this, we recommend disabling TRAP caching by passing the `trap-caching: false` input to the `init` Action. [#3795](https://github.com/github/codeql-action/pull/3795)
- The Git version 2.36.0 requirement for improved incremental analysis now only applies to repositories that contain submodules. [#3789](https://github.com/github/codeql-action/pull/3789)
- Python analysis on GHES no longer extracts the standard library, relying instead on models of the standard library. This should result in significantly faster extraction and analysis times, while the effect on alerts should be minimal. [#3794](https://github.com/github/codeql-action/pull/3794)
- Fixed a bug in the validation of OIDC configurations for private registries that was added in CodeQL Action 4.33.0 / 3.33.0. [#3807](https://github.com/github/codeql-action/pull/3807)
- Update default CodeQL bundle version to [2.25.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2). [#3823](https://github.com/github/codeql-action/pull/3823)

## 4.35.1 - 27 Mar 2026

- Fix incorrect minimum required Git version for [improved incremental analysis](https://github.com/github/roadmap/issues/1158): it should have been 2.36.0, not 2.11.0. [#3781](https://github.com/github/codeql-action/pull/3781)

## 4.35.0 - 27 Mar 2026

- Reduced the minimum Git version required for [improved incremental analysis](https://github.com/github/roadmap/issues/1158) from 2.38.0 to 2.11.0. [#3767](https://github.com/github/codeql-action/pull/3767)
- Update default CodeQL bundle version to [2.25.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.1). [#3773](https://github.com/github/codeql-action/pull/3773)

## 4.34.1 - 20 Mar 2026

- Downgrade default CodeQL bundle version to [2.24.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3) due to issues with a small percentage of Actions and JavaScript analyses. [#3762](https://github.com/github/codeql-action/pull/3762)

## 4.34.0 - 20 Mar 2026

- Added an experimental change which disables TRAP caching when [improved incremental analysis](https://github.com/github/roadmap/issues/1158) is enabled, since improved incremental analysis supersedes TRAP caching. This will improve performance and reduce Actions cache usage. We expect to roll this change out to everyone in March. [#3569](https://github.com/github/codeql-action/pull/3569)
- We are rolling out improved incremental analysis to C/C++ analyses that use build mode `none`. We expect this rollout to be complete by the end of April 2026. [#3584](https://github.com/github/codeql-action/pull/3584)
- Update default CodeQL bundle version to [2.25.0](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.0). [#3585](https://github.com/github/codeql-action/pull/3585)

## 4.33.0 - 16 Mar 2026

- Upcoming change: Starting April 2026, the CodeQL Action will skip collecting file coverage information on pull requests to improve analysis performance. File coverage information will still be computed on non-PR analyses. Pull request analyses will log a warning about this upcoming change. [#3562](https://github.com/github/codeql-action/pull/3562)

  To opt out of this change:
  - **Repositories owned by an organization:** Create a custom repository property with the name `github-codeql-file-coverage-on-prs` and the type "True/false", then set this property to `true` in the repository's settings. For more information, see [Managing custom properties for repositories in your organization](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization). Alternatively, if you are using an advanced setup workflow, you can set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in your workflow.
  - **User-owned repositories using default setup:** Switch to an advanced setup workflow and set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in your workflow.
  - **User-owned repositories using advanced setup:** Set the `CODEQL_ACTION_FILE_COVERAGE_ON_PRS` environment variable to `true` in your workflow.
- Fixed [a bug](https://github.com/github/codeql-action/issues/3555) which caused the CodeQL Action to fail loading repository properties if a "Multi select" repository property was configured for the repository. [#3557](https://github.com/github/codeql-action/pull/3557)
- The CodeQL Action now loads [custom repository properties](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization) on GitHub Enterprise Server, enabling the customization of features such as `github-codeql-disable-overlay` that was previously only available on GitHub.com. [#3559](https://github.com/github/codeql-action/pull/3559)
- Once [private package registries](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries) can be configured with OIDC-based authentication for organizations, the CodeQL Action will now be able to accept such configurations. [#3563](https://github.com/github/codeql-action/pull/3563)
- Fixed the retry mechanism for database uploads. Previously this would fail with the error "Response body object should not be disturbed or locked". [#3564](https://github.com/github/codeql-action/pull/3564)
- A warning is now emitted if the CodeQL Action detects a repository property whose name suggests that it relates to the CodeQL Action, but which is not one of the properties recognised by the current version of the CodeQL Action. [#3570](https://github.com/github/codeql-action/pull/3570)

## 4.32.6 - 05 Mar 2026

- Update default CodeQL bundle version to [2.24.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3). [#3548](https://github.com/github/codeql-action/pull/3548)

## 4.32.5 - 02 Mar 2026

- Repositories owned by an organization can now set up the `github-codeql-disable-overlay` custom repository property to disable [improved incremental analysis for CodeQL](https://github.com/github/roadmap/issues/1158). First, create a custom repository property with the name `github-codeql-disable-overlay` and the type "True/false" in the organization's settings. Then in the repository's settings, set this property to `true` to disable improved incremental analysis. For more information, see [Managing custom properties for repositories in your organization](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization). This feature is not yet available on GitHub Enterprise Server. [#3507](https://github.com/github/codeql-action/pull/3507)
- Added an experimental change so that when [improved incremental analysis](https://github.com/github/roadmap/issues/1158) fails on a runner — potentially due to insufficient disk space — the failure is recorded in the Actions cache so that subsequent runs will automatically skip improved incremental analysis until something changes (e.g. a larger runner is provisioned or a new CodeQL version is released). We expect to roll this change out to everyone in March. [#3487](https://github.com/github/codeql-action/pull/3487)
- The minimum memory check for improved incremental analysis is now skipped for CodeQL 2.24.3 and later, which has reduced peak RAM usage. [#3515](https://github.com/github/codeql-action/pull/3515)
- Reduced log levels for best-effort private package registry connection check failures to reduce noise from workflow annotations. [#3516](https://github.com/github/codeql-action/pull/3516)
- Added an experimental change which lowers the minimum disk space requirement for [improved incremental analysis](https://github.com/github/roadmap/issues/1158), enabling it to run on standard GitHub Actions runners. We expect to roll this change out to everyone in March. [#3498](https://github.com/github/codeql-action/pull/3498)
- Added an experimental change which allows the `start-proxy` action to resolve the CodeQL CLI version from feature flags instead of using the linked CLI bundle version. We expect to roll this change out to everyone in March. [#3512](https://github.com/github/codeql-action/pull/3512)
- The previously experimental changes from versions 4.32.3, 4.32.4, 3.32.3 and 3.32.4 are now enabled by default. [#3503](https://github.com/github/codeql-action/pull/3503), [#3504](https://github.com/github/codeql-action/pull/3504)

## 4.32.4 - 20 Feb 2026

- Update default CodeQL bundle version to [2.24.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.2). [#3493](https://github.com/github/codeql-action/pull/3493)
- Added an experimental change which improves how certificates are generated for the authentication proxy that is used by the CodeQL Action in Default Setup when [private package registries are configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries). This is expected to generate more widely compatible certificates and should have no impact on analyses which are working correctly already. We expect to roll this change out to everyone in February. [#3473](https://github.com/github/codeql-action/pull/3473)
- When the CodeQL Action is run [with debugging enabled in Default Setup](https://docs.github.com/en/code-security/how-tos/scan-code-for-vulnerabilities/troubleshooting/troubleshooting-analysis-errors/logs-not-detailed-enough#creating-codeql-debugging-artifacts-for-codeql-default-setup) and [private package registries are configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries), the "Setup proxy for registries" step will output additional diagnostic information that can be used for troubleshooting. [#3486](https://github.com/github/codeql-action/pull/3486)
- Added a setting which allows the CodeQL Action to enable network debugging for Java programs. This will help GitHub staff support customers with troubleshooting issues in GitHub-managed CodeQL workflows, such as Default Setup. This setting can only be enabled by GitHub staff. [#3485](https://github.com/github/codeql-action/pull/3485)
- Added a setting which enables GitHub-managed workflows, such as Default Setup, to use a [nightly CodeQL CLI release](https://github.com/dsp-testing/codeql-cli-nightlies) instead of the latest, stable release that is used by default. This will help GitHub staff support customers whose analyses for a given repository or organization require early access to a change in an upcoming CodeQL CLI release. This setting can only be enabled by GitHub staff. [#3484](https://github.com/github/codeql-action/pull/3484)

## 4.32.3 - 13 Feb 2026

- Added experimental support for testing connections to [private package registries](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries). This feature is not currently enabled for any analysis. In the future, it may be enabled by default for Default Setup. [#3466](https://github.com/github/codeql-action/pull/3466)

## 4.32.2 - 05 Feb 2026

- Update default CodeQL bundle version to [2.24.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.1). [#3460](https://github.com/github/codeql-action/pull/3460)

## 4.32.1 - 02 Feb 2026

- A warning is now shown in Default Setup workflow logs if a [private package registry is configured](https://docs.github.com/en/code-security/how-tos/secure-at-scale/configure-organization-security/manage-usage-and-access/giving-org-access-private-registries) using a GitHub Personal Access Token (PAT), but no username is configured. [#3422](https://github.com/github/codeql-action/pull/3422)
- Fixed a bug which caused the CodeQL Action to fail when repository properties cannot successfully be retrieved. [#3421](https://github.com/github/codeql-action/pull/3421)

## 4.32.0 - 26 Jan 2026

- Update default CodeQL bundle version to [2.24.0](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.0). [#3425](https://github.com/github/codeql-action/pull/3425)

## 4.31.11 - 23 Jan 2026

- When running a Default Setup workflow with [Actions debugging enabled](https://docs.github.com/en/actions/how-tos/monitor-workflows/enable-debug-logging), the CodeQL Action will now use more unique names when uploading logs from the Dependabot authentication proxy as workflow artifacts. This ensures that the artifact names do not clash between multiple jobs in a build matrix. [#3409](https://github.com/github/codeql-action/pull/3409)
- Improved error handling throughout the CodeQL Action. [#3415](https://github.com/github/codeql-action/pull/3415)
- Added experimental support for automatically excluding [generated files](https://docs.github.com/en/repositories/working-with-files/managing-files/customizing-how-changed-files-appear-on-github) from the analysis. This feature is not currently enabled for any analysis. In the future, it may be enabled by default for some GitHub-managed analyses. [#3318](https://github.com/github/codeql-action/pull/3318)
- The changelog extracts that are included with releases of the CodeQL Action are now shorter to avoid duplicated information from appearing in Dependabot PRs. [#3403](https://github.com/github/codeql-action/pull/3403)

## 4.31.10 - 12 Jan 2026

- Update default CodeQL bundle version to 2.23.9. [#3393](https://github.com/github/codeql-action/pull/3393)

## 4.31.9 - 16 Dec 2025

No user facing changes.

## 4.31.8 - 11 Dec 2025

- Update default CodeQL bundle version to 2.23.8. [#3354](https://github.com/github/codeql-action/pull/3354)

## 4.31.7 - 05 Dec 2025

- Update default CodeQL bundle version to 2.23.7. [#3343](https://github.com/github/codeql-action/pull/3343)

## 4.31.6 - 01 Dec 2025

No user facing changes.

## 4.31.5 - 24 Nov 2025

- Update default CodeQL bundle version to 2.23.6. [#3321](https://github.com/github/codeql-action/pull/3321)

## 4.31.4 - 18 Nov 2025

No user facing changes.

## 4.31.3 - 13 Nov 2025

- CodeQL Action v3 will be deprecated in December 2026.  The Action now logs a warning for customers who are running v3 but could be running v4. For more information, see [Upcoming deprecation of CodeQL Action v3](https://github.blog/changelog/2025-10-28-upcoming-deprecation-of-codeql-action-v3/).
- Update default CodeQL bundle version to 2.23.5. [#3288](https://github.com/github/codeql-action/pull/3288)

## 4.31.2 - 30 Oct 2025

No user facing changes.

## 4.31.1 - 30 Oct 2025

- The `add-snippets` input has been removed from the `analyze` action. This input has been deprecated since CodeQL Action 3.26.4 in August 2024 when this removal was announced.

## 4.31.0 - 24 Oct 2025

- Bump minimum CodeQL bundle version to 2.17.6. [#3223](https://github.com/github/codeql-action/pull/3223)
- When SARIF files are uploaded by the `analyze` or `upload-sarif` actions, the CodeQL Action automatically performs post-processing steps to prepare the data for the upload. Previously, these post-processing steps were only performed before an upload took place. We are now changing this so that the post-processing steps will always be performed, even when the SARIF files are not uploaded. This does not change anything for the `upload-sarif` action. For `analyze`, this may affect Advanced Setup for CodeQL users who specify a value other than `always` for the `upload` input. [#3222](https://github.com/github/codeql-action/pull/3222)

## 4.30.9 - 17 Oct 2025

- Update default CodeQL bundle version to 2.23.3. [#3205](https://github.com/github/codeql-action/pull/3205)
- Experimental: A new `setup-codeql` action has been added which is similar to `init`, except it only installs the CodeQL CLI and does not initialize a database. Do not use this in production as it is part of an internal experiment and subject to change at any time. [#3204](https://github.com/github/codeql-action/pull/3204)

## 4.30.8 - 10 Oct 2025

No user facing changes.

## 4.30.7 - 06 Oct 2025

- [v4+ only] The CodeQL Action now runs on Node.js v24. [#3169](https://github.com/github/codeql-action/pull/3169)

## 3.30.6 - 02 Oct 2025

- Update default CodeQL bundle version to 2.23.2. [#3168](https://github.com/github/codeql-action/pull/3168)

## 3.30.5 - 26 Sep 2025

- We fixed a bug that was introduced in `3.30.4` with `upload-sarif` which resulted in files without a `.sarif` extension not getting uploaded. [#3160](https://github.com/github/codeql-action/pull/3160)

## 3.30.4 - 25 Sep 2025

- We have improved the CodeQL Action's ability to validate that the workflow it is used in does not use different versions of the CodeQL Action for different workflow steps. Mixing different versions of the CodeQL Action in the same workflow is unsupported and can lead to unpredictable results. A warning will now be emitted from the `codeql-action/init` step if different versions of the CodeQL Action are detected in the workflow file. Additionally, an error will now be thrown by the other CodeQL Action steps if they load a configuration file that was generated by a different version of the `codeql-action/init` step. [#3099](https://github.com/github/codeql-action/pull/3099) and [#3100](https://github.com/github/codeql-action/pull/3100)
- We added support for reducing the size of dependency caches for Java analyses, which will reduce cache usage and speed up workflows. This will be enabled automatically at a later time. [#3107](https://github.com/github/codeql-action/pull/3107)
- You can now run the latest CodeQL nightly bundle by passing `tools: nightly` to the `init` action. In general, the nightly bundle is unstable and we only recommend running it when directed by GitHub staff. [#3130](https://github.com/github/codeql-action/pull/3130)
- Update default CodeQL bundle version to 2.23.1. [#3118](https://github.com/github/codeql-action/pull/3118)

## 3.30.3 - 10 Sep 2025

No user facing changes.

## 3.30.2 - 09 Sep 2025

- Fixed a bug which could cause language autodetection to fail. [#3084](https://github.com/github/codeql-action/pull/3084)
- Experimental: The `quality-queries` input that was added in `3.29.2` as part of an internal experiment is now deprecated and will be removed in an upcoming version of the CodeQL Action. It has been superseded by a new `analysis-kinds` input, which is part of the same internal experiment. Do not use this in production as it is subject to change at any time. [#3064](https://github.com/github/codeql-action/pull/3064)

## 3.30.1 - 05 Sep 2025

- Update default CodeQL bundle version to 2.23.0. [#3077](https://github.com/github/codeql-action/pull/3077)

## 3.30.0 - 01 Sep 2025

- Reduce the size of the CodeQL Action, speeding up workflows by approximately 4 seconds. [#3054](https://github.com/github/codeql-action/pull/3054)

## 3.29.11 - 21 Aug 2025

- Update default CodeQL bundle version to 2.22.4. [#3044](https://github.com/github/codeql-action/pull/3044)

## 3.29.10 - 18 Aug 2025

No user facing changes.

## 3.29.9 - 12 Aug 2025

No user facing changes.

## 3.29.8 - 08 Aug 2025

- Fix an issue where the Action would autodetect unsupported languages such as HTML. [#3015](https://github.com/github/codeql-action/pull/3015)

## 3.29.7 - 07 Aug 2025

This release rolls back 3.29.6 to address issues with language autodetection. It is identical to 3.29.5.

## 3.29.6 - 07 Aug 2025

- The `cleanup-level` input to the `analyze` Action is now deprecated. The CodeQL Action has written a limited amount of intermediate results to the database since version 2.2.5, and now automatically manages cleanup. [#2999](https://github.com/github/codeql-action/pull/2999)
- Update default CodeQL bundle version to 2.22.3. [#3000](https://github.com/github/codeql-action/pull/3000)

## 3.29.5 - 29 Jul 2025

- Update default CodeQL bundle version to 2.22.2. [#2986](https://github.com/github/codeql-action/pull/2986)

## 3.29.4 - 23 Jul 2025

No user facing changes.

## 3.29.3 - 21 Jul 2025

No user facing changes.

## 3.29.2 - 30 Jun 2025

- Experimental: When the `quality-queries` input for the `init` action is provided with an argument, separate `.quality.sarif` files are produced and uploaded for each language with the results of the specified queries. Do not use this in production as it is part of an internal experiment and subject to change at any time. [#2935](https://github.com/github/codeql-action/pull/2935)

## 3.29.1 - 27 Jun 2025

- Fix bug in PR analysis where user-provided `include` query filter fails to exclude non-included queries. [#2938](https://github.com/github/codeql-action/pull/2938)
- Update default CodeQL bundle version to 2.22.1. [#2950](https://github.com/github/codeql-action/pull/2950)

- Remove support for combining SARIF files from a single upload for GHES 3.18, see [the changelog post](https://github.blog/changelog/2024-05-06-code-scanning-will-stop-combining-runs-from-a-single-upload/). [#2959](https://github.com/github/codeql-action/pull/2959)

## 3.28.19 - 03 Jun 2025

- The CodeQL Action no longer includes its own copy of the extractor for the `actions` language, which is currently in public preview.
  The `actions` extractor has been included in the CodeQL CLI since v2.20.6. If your workflow has enabled the `actions` language _and_ you have pinned
  your `tools:` property to a specific version of the CodeQL CLI earlier than v2.20.6, you will need to update to at least CodeQL v2.20.6 or disable
  `actions` analysis.

[#2557](https://github.com/github/codeql-action/pull/2557)
- Update default CodeQL bundle version to 2.19.2. [#2552](https://github.com/github/codeql-action/pull/2552)

## 3.26.13 - 14 Oct 2024

No user facing changes.

## 3.26.12 - 07 Oct 2024

- _Upcoming breaking change_: Add a deprecation warning for customers using CodeQL version 2.14.5 and earlier. These versions of CodeQL were discontinued on 24 September 2024 alongside GitHub Enterprise Server 3.10, and will be unsupported by CodeQL Action versions 3.27.0 and later and versions 2.27.0 and later. [#2520](https://github.com/github/codeql-action/pull/2520)

  - If you are using one of these versions, please update to CodeQL CLI version 2.14.6 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 2.13.5 and 2.14.5, you can replace `github/codeql-action/*@v3` by `github/codeql-action/*@v3.26.11` and `github/codeql-action/*@v2` by `github/codeql-action/*@v2.26.11` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.

## 3.26.11 - 03 Oct 2024

- _Upcoming breaking change_: Add support for using `actions/download-artifact@v4` to programmatically consume CodeQL Action debug artifacts.

  Starting November 30, 2024, GitHub.com customers will [no longer be able to use `actions/download-artifact@v3`](https://github.blog/changelog/2024-04-16-deprecation-notice-v3-of-the-artifact-actions/). Therefore, to avoid breakage, customers who programmatically download the CodeQL Action debug artifacts should set the `CODEQL_ACTION_ARTIFACT_V4_UPGRADE` environment variable to `true` and bump `actions/download-artifact@v3` to `actions/download-artifact@v4` in their workflows. The CodeQL Action will enable this behavior by default in early November and workflows that have not yet bumped `actions/download-artifact@v3` to `actions/download-artifact@v4` will begin failing then.

  This change is currently unavailable for GitHub Enterprise Server customers, as `actions/upload-artifact@v4` and `actions/download-artifact@v4` are not yet compatible with GHES.

[#2375](https://github.com/github/codeql-action/pull/2375)
  - If you are using one of these versions, please update to CodeQL CLI version 2.13.5 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 2.12.6 and 2.13.4, you can replace `github/codeql-action/*@v3` by `github/codeql-action/*@v3.25.13` and `github/codeql-action/*@v2` by `github/codeql-action/*@v2.25.13` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.

## 3.25.12 - 12 Jul 2024

- Improve the reliability and performance of analyzing code when analyzing a compiled language with the `autobuild` [build mode](https://docs.github.com/en/code-security/code-scanning/creating-an-advanced-setup-for-code-scanning/codeql-code-scanning-for-compiled-languages#codeql-build-modes) on GitHub Enterprise Server. This feature is already available to GitHub.com users. [#2353](https://github.com/github/codeql-action/pull/2353)
- Update default CodeQL bundle version to 2.18.0. [#2364](https://github.com/github/codeql-action/pull/2364)

## 3.25.9 - 12 Jun 2024

- Avoid failing database creation if the database folder already exists and contains some unexpected files. Requires CodeQL 2.18.0 or higher. [#2330](https://github.com/github/codeql-action/pull/2330)
- The init Action will attempt to clean up the database cluster directory before creating a new database and at the end of the job. This will help to avoid issues where the database cluster directory is left in an inconsistent state. [#2332](https://github.com/github/codeql-action/pull/2332)

## 3.25.8 - 04 Jun 2024

- Update default CodeQL bundle version to 2.17.4. [#2321](https://github.com/github/codeql-action/pull/2321)

## 3.25.7 - 31 May 2024

- The `tools: latest` input to the `init` Action has been renamed to `tools: linked`. This option specifies that the Action should use the tools shipped at the same time as the Action. The old name will continue to work for backwards compatibility, but we recommend that new workflows use the new name. [#2281](https://github.com/github/codeql-action/pull/2281)

- Workflows running on `macos-latest` using CodeQL CLI versions before v2.15.1 will need to either upgrade their CLI version to v2.15.1 or newer, or change the platform to an Intel macOS runner, such as `macos-12`. ARM machines with SIP disabled, including the newest `macos-latest` image, are unsupported for CLI versions before 2.15.1. [#2261](https://github.com/github/codeql-action/pull/2261)

## 3.25.2 - 22 Apr 2024

No user facing changes.

## 3.25.1 - 17 Apr 2024

- We are rolling out a feature in April/May 2024 that improves the reliability and performance of analyzing code when analyzing a compiled language with the `autobuild` [build mode](https://docs.github.com/en/code-security/code-scanning/creating-an-advanced-setup-for-code-scanning/codeql-code-scanning-for-compiled-languages#codeql-build-modes). [#2235](https://github.com/github/codeql-action/pull/2235)
- Fix a bug where the `init` Action would fail if `--overwrite` was specified in `CODEQL_ACTION_EXTRA_OPTIONS`. [#2245](https://github.com/github/codeql-action/pull/2245)

## 3.25.0 - 15 Apr 2024

- The deprecated feature for extracting dependencies for a Python analysis has been removed. [#2224](https://github.com/github/codeql-action/pull/2224)

  As a result, the following inputs and environment variables are now ignored:

  - The `setup-python-dependencies` input to the `init` Action
  - The `CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION` environment variable

  We recommend removing any references to these from your workflows. For more information, see the release notes for CodeQL Action v3.23.0 and v2.23.0.

## 3.24.10 - 05 Apr 2024

- Update default CodeQL bundle version to 2.17.0. [#2219](https://github.com/github/codeql-action/pull/2219)
- Add a deprecation warning for customers using CodeQL version 2.12.5 and earlier. These versions of CodeQL were discontinued on 26 March 2024 alongside GitHub Enterprise Server 3.8, and will be unsupported by CodeQL Action versions 3.25.0 and later and versions 2.25.0 and later. [#2220](https://github.com/github/codeql-action/pull/2220)
  - If you are using one of these versions, please update to CodeQL CLI version 2.12.6 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 2.11.6 and 2.12.5, you can replace `github/codeql-action/*@v3` by `github/codeql-action/*@v3.24.10` and `github/codeql-action/*@v2` by `github/codeql-action/*@v2.24.10` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.

## 3.24.0 - 02 Feb 2024

- CodeQL Python analysis will no longer install dependencies on GitHub Enterprise Server, as is already the case for GitHub.com. See [release notes for 3.23.0](#3230---08-jan-2024) for more details. [#2106](https://github.com/github/codeql-action/pull/2106)

## 3.23.2 - 26 Jan 2024

- On Linux, the maximum possible value for the `--threads` option now respects the CPU count as specified in `cgroup` files to more accurately reflect the number of available cores when running in containers. [#2083](https://github.com/github/codeql-action/pull/2083)
- Update default CodeQL bundle version to 2.16.1. [#2096](https://github.com/github/codeql-action/pull/2096)

## 3.23.0 - 08 Jan 2024

- We are rolling out a feature in January 2024 that will disable Python dependency installation by default for all users. This improves the speed of analysis while having only a very minor impact on results. You can override this behavior by setting `CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION=false` in your workflow, however we plan to remove this ability in future versions of the CodeQL Action. [#2031](https://github.com/github/codeql-action/pull/2031)
- The CodeQL Action now requires CodeQL version 2.11.6 or later. For more information, see [the corresponding changelog entry for CodeQL Action version 2.22.7](#2227---16-nov-2023). [#2009](https://github.com/github/codeql-action/pull/2009)

## 3.22.12 - 22 Dec 2023

- Update default CodeQL bundle version to 2.15.5. [#2047](https://github.com/github/codeql-action/pull/2047)

## 3.22.11 - 13 Dec 2023

- [v3+ only] The CodeQL Action now runs on Node.js v20. [#2006](https://github.com/github/codeql-action/pull/2006)

## 2.22.10 - 12 Dec 2023

- Update default CodeQL bundle version to 2.15.4. [#2016](https://github.com/github/codeql-action/pull/2016)

## 2.22.9 - 07 Dec 2023

No user facing changes.

## 2.22.8 - 23 Nov 2023

- Update default CodeQL bundle version to 2.15.3. [#2001](https://github.com/github/codeql-action/pull/2001)

## 2.22.7 - 16 Nov 2023

- Add a deprecation warning for customers using CodeQL version 2.11.5 and earlier. These versions of CodeQL were discontinued on 8 November 2023 alongside GitHub Enterprise Server 3.7, and will be unsupported by CodeQL Action v2.23.0 and later. [#1993](https://github.com/github/codeql-action/pull/1993)
  - If you are using one of these versions, please update to CodeQL CLI version 2.11.6 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 2.10.5 and 2.11.5, you can replace `github/codeql-action/*@v2` by `github/codeql-action/*@v2.22.7` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.

## 2.22.6 - 14 Nov 2023

- Customers running Python analysis on macOS using version 2.14.6 or earlier of the CodeQL CLI should upgrade to CodeQL CLI version 2.15.0 or later. If you do not wish to upgrade the CodeQL CLI, ensure that you are using Python version 3.11 or earlier, as CodeQL version 2.14.6 and earlier do not support Python 3.12. You can achieve this by adding a [`setup-python`](https://github.com/actions/setup-python) step to your code scanning workflow before the step that invokes `github/codeql-action/init`.
- Update default CodeQL bundle version to 2.15.2. [#1978](https://github.com/github/codeql-action/pull/1978)

## 2.22.5 - 27 Oct 2023

No user facing changes.

- Update default CodeQL bundle version to 2.15.1. [#1953](https://github.com/github/codeql-action/pull/1953)
- Users will begin to see warnings on Node.js 16 deprecation in their Actions logs on code scanning runs starting October 23, 2023.
  - All code scanning workflows should continue to succeed regardless of the warning.
  - The team at GitHub maintaining the CodeQL Action is aware of the deprecation timeline and actively working on creating another version of the CodeQL Action, v3, that will bump us to Node 20.
  - For more information, and to communicate with the maintaining team, please use [this issue](https://github.com/github/codeql-action/issues/1959).

## 2.22.3 - 13 Oct 2023

- Provide an authentication token when downloading the CodeQL Bundle from the API of a GitHub Enterprise Server instance. [#1945](https://github.com/github/codeql-action/pull/1945)

## 2.22.1 - 09 Oct 2023

- Add a workaround for 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. In this case, if Python 3.11 is not found, then the workflow will fail. [#1928](https://github.com/github/codeql-action/pull/1928)

## 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](https://github.com/github/codeql-action/pull/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."](https://github.blog/changelog/2023-09-29-codeql-code-scanning-deprecates-ml-powered-alerts/) [#1910](https://github.com/github/codeql-action/pull/1910)
- Fix a bug which prevented tracing of projects using Go 1.21 and above on Linux. [#1909](https://github.com/github/codeql-action/pull/1909)

- Update default CodeQL bundle version to 2.14.6. [#1897](https://github.com/github/codeql-action/pull/1897)
- We are rolling out a feature in October 2023 that will improve the success rate of C/C++ autobuild. [#1889](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/1903)
- Add a warning to help customers avoid inadvertently analyzing the same CodeQL language in multiple matrix jobs. [#1901](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/1883)

## 2.21.7 - 14 Sep 2023

- Update default CodeQL bundle version to 2.14.5. [#1882](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/1866)
- Enable improved file coverage information for GitHub Enterprise Server users. This feature is already available to GitHub.com users. [#1867](https://github.com/github/codeql-action/pull/1867)
- Update default CodeQL bundle version to 2.14.4. [#1873](https://github.com/github/codeql-action/pull/1873)

- 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)

## 2.21.4 - 14 Aug 2023

- Update default CodeQL bundle version to 2.14.2. [#1831](https://github.com/github/codeql-action/pull/1831)
- Log a warning if the amount of available disk space runs low during a code scanning run. [#1825](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/1832)
- Fix an issue that first appeared in CodeQL Action v2.21.2 that prevented CodeQL invocations from being logged. [#1833](https://github.com/github/codeql-action/pull/1833)
- We are rolling out a feature in August 2023 that will improve the quality of file coverage information. [#1835](https://github.com/github/codeql-action/pull/1835)

- We are rolling out a feature in August 2023 that adds beta support for [Project Lombok](https://projectlombok.org/) when analyzing Java. [#1809](https://github.com/github/codeql-action/pull/1809)
- Reduce disk space usage when downloading the CodeQL bundle. [#1820](https://github.com/github/codeql-action/pull/1820)

## 2.21.2 - 28 Jul 2023

- Update default CodeQL bundle version to 2.14.1. [#1797](https://github.com/github/codeql-action/pull/1797)
- Avoid duplicating the analysis summary within the logs. [#1811](https://github.com/github/codeql-action/pull/1811)

## 2.21.1 - 26 Jul 2023

- Improve the handling of fatal errors from the CodeQL CLI. [#1795](https://github.com/github/codeql-action/pull/1795)
- Add the `sarif-output` output to the analyze action that contains the path to the directory of the generated SARIF. [#1799](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/1760)
- Update default CodeQL bundle version to 2.14.0. [#1762](https://github.com/github/codeql-action/pull/1762)

## 2.20.3 - 06 Jul 2023

- Update default CodeQL bundle version to 2.13.5. [#1743](https://github.com/github/codeql-action/pull/1743)

## 2.20.2 - 03 Jul 2023

No user facing changes.

## 2.20.1 - 21 Jun 2023

- Update default CodeQL bundle version to 2.13.4. [#1721](https://github.com/github/codeql-action/pull/1721)
- Experimental: add a new `resolve-environment` action which attempts to infer a configuration for the build environment that is required to build a given project. Do not use this in production as it is part of an internal experiment and subject to change at any time.

## 2.20.0 - 13 Jun 2023

- Bump the version of the Action to 2.20.0. This ensures that users who received a Dependabot upgrade to [`cdcdbb5`](https://github.com/github/codeql-action/commit/cdcdbb579706841c47f7063dda365e292e5cad7a), which was mistakenly marked as Action version 2.13.4, continue to receive updates to the CodeQL Action. Full details in [#1729](https://github.com/github/codeql-action/pull/1729)

## 2.3.6 - 01 Jun 2023

- Update default CodeQL bundle version to 2.13.3. [#1698](https://github.com/github/codeql-action/pull/1698)

## 2.3.5 - 25 May 2023

- Allow invalid URIs to be used as values to `artifactLocation.uri` properties. This reverses a change from [#1668](https://github.com/github/codeql-action/pull/1668) that inadvertently led to stricter validation of some URI values. [#1705](https://github.com/github/codeql-action/pull/1705)
- Gracefully handle invalid URIs when fingerprinting. [#1694](https://github.com/github/codeql-action/pull/1694)

## 2.3.4 - 24 May 2023

- Updated the SARIF 2.1.0 JSON schema file to the latest from [oasis-tcs/sarif-spec](https://github.com/oasis-tcs/sarif-spec/blob/123e95847b13fbdd4cbe2120fa5e33355d4a042b/Schemata/sarif-schema-2.1.0.json). [#1668](https://github.com/github/codeql-action/pull/1668)
- We are rolling out a feature in May 2023 that will disable Python dependency installation for new users of the CodeQL Action. This improves the speed of analysis while having only a very minor impact on results. [#1676](https://github.com/github/codeql-action/pull/1676)
- We are improving the way that [CodeQL bundles](https://github.com/github/codeql-action/releases) are tagged to make it possible to easily identify bundles by their CodeQL semantic version. [#1682](https://github.com/github/codeql-action/pull/1682)
  - As of CodeQL CLI 2.13.4, CodeQL bundles will be tagged using semantic versions, for example `codeql-bundle-v2.13.4`, instead of timestamps, like `codeql-bundle-20230615`.
  - This change does not affect the majority of workflows, and we will not be changing tags for existing bundle releases.
  - Some workflows with custom logic that depends on the specific format of the CodeQL bundle tag may need to be updated. For example, if your workflow matches CodeQL bundle tag names against a `codeql-bundle-yyyymmdd` pattern, you should update it to also recognize `codeql-bundle-vx.y.z` tags.
- Remove the requirement for `on.push` and `on.pull_request` to trigger on the same branches. [#1675](https://github.com/github/codeql-action/pull/1675)

## 2.3.3 - 04 May 2023

- Update default CodeQL bundle version to 2.13.1. [#1664](https://github.com/github/codeql-action/pull/1664)
- You can now configure CodeQL within your code scanning workflow by passing a `config` input to the `init` Action. See [Using a custom configuration file](https://aka.ms/code-scanning-docs/config-file) for more information about configuring code scanning. [#1590](https://github.com/github/codeql-action/pull/1590)

## 2.3.2 - 27 Apr 2023

No user facing changes.

## 2.3.1 - 26 Apr 2023

No user facing changes.

## 2.3.0 - 21 Apr 2023

- Update default CodeQL bundle version to 2.13.0. [#1649](https://github.com/github/codeql-action/pull/1649)
- Bump the minimum CodeQL bundle version to 2.8.5. [#1618](https://github.com/github/codeql-action/pull/1618)

## 2.2.12 - 13 Apr 2023

- Include the value of the `GITHUB_RUN_ATTEMPT` environment variable in the telemetry sent to GitHub. [#1640](https://github.com/github/codeql-action/pull/1640)
- Improve the ease of debugging failed runs configured using [default setup](https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/configuring-code-scanning-for-a-repository#configuring-code-scanning-automatically). The CodeQL Action will now upload diagnostic information to Code Scanning from failed runs configured using default setup. You can view this diagnostic information on the [tool status page](https://docs.github.com/en/code-security/code-scanning/automatically-scanning-your-code-for-vulnerabilities-and-errors/about-the-tool-status-page). [#1619](https://github.com/github/codeql-action/pull/1619)

## 2.2.11 - 06 Apr 2023

No user facing changes.

## 2.2.10 - 05 Apr 2023

- Update default CodeQL bundle version to 2.12.6. [#1629](https://github.com/github/codeql-action/pull/1629)

## 2.2.9 - 27 Mar 2023

- Customers post-processing the SARIF output of the `analyze` Action before uploading it to Code Scanning will benefit from an improved debugging experience. [#1598](https://github.com/github/codeql-action/pull/1598)
  - The CodeQL Action will now upload a SARIF file with debugging information to Code Scanning on failed runs for customers using `upload: false`. Previously, this was only available for customers using the default value of the `upload` input.
  - The `upload` input to the `analyze` Action now accepts the following values:
    - `always` is the default value, which uploads the SARIF file to Code Scanning for successful and failed runs.
    - `failure-only` is recommended for customers post-processing the SARIF file before uploading it to Code Scanning. This option uploads debugging information to Code Scanning for failed runs to improve the debugging experience.
    - `never` avoids uploading the SARIF file to Code Scanning even if the code scanning run fails. This is not recommended for external users since it complicates debugging.
    - The legacy `true` and `false` options will be interpreted as `always` and `failure-only` respectively.

## 2.2.8 - 22 Mar 2023

- Update default CodeQL bundle version to 2.12.5. [#1585](https://github.com/github/codeql-action/pull/1585)

## 2.2.7 - 15 Mar 2023

No user facing changes.

## 2.2.6 - 10 Mar 2023

- Update default CodeQL bundle version to 2.12.4. [#1561](https://github.com/github/codeql-action/pull/1561)

## 2.2.5 - 24 Feb 2023

- Update default CodeQL bundle version to 2.12.3. [#1543](https://github.com/github/codeql-action/pull/1543)

## 2.2.4 - 10 Feb 2023

No user facing changes.

## 2.2.3 - 08 Feb 2023

- Update default CodeQL bundle version to 2.12.2. [#1518](https://github.com/github/codeql-action/pull/1518)

## 2.2.2 - 06 Feb 2023

- Fix an issue where customers using the CodeQL Action with the [CodeQL Action sync tool](https://docs.github.com/en/enterprise-server@3.7/admin/code-security/managing-github-advanced-security-for-your-enterprise/configuring-code-scanning-for-your-appliance#configuring-codeql-analysis-on-a-server-without-internet-access) would not be able to obtain the CodeQL tools. [#1517](https://github.com/github/codeql-action/pull/1517)

## 2.2.1 - 27 Jan 2023

No user facing changes.

## 2.2.0 - 26 Jan 2023

- Improve stability when choosing the default version of CodeQL to use in code scanning workflow runs on Actions on GitHub.com. [#1475](https://github.com/github/codeql-action/pull/1475)
  - This change addresses customer reports of code scanning alerts on GitHub.com being closed and reopened during the rollout of new versions of CodeQL in the GitHub Actions [runner images](https://github.com/actions/runner-images).
  - **No change is required for the majority of workflows**, including:
    - Workflows on GitHub.com hosted runners using the latest version (`v2`) of the CodeQL Action.
    - Workflows on GitHub.com hosted runners that are pinned to specific versions of the CodeQL Action from `v2.2.0` onwards.
    - Workflows on GitHub Enterprise Server.
  - **A change may be required** for workflows on GitHub.com hosted runners that are pinned to specific versions of the CodeQL Action before `v2.2.0` (e.g. `v2.1.32`):
    - Previously, these workflows would obtain the latest version of CodeQL from the Actions runner image.
    - Now, these workflows will download an older, compatible version of CodeQL from GitHub Releases. To use this older version, no change is required. To use the newest version of CodeQL, please update your workflows to reference the latest version of the CodeQL Action (`v2`).
  - **Internal changes**
    - These changes will not affect the majority of code scanning workflows. Continue reading only if your workflow uses [@actions/tool-cache](https://github.com/actions/toolkit/tree/main/packages/tool-cache) or relies on the precise location of CodeQL within the Actions tool cache.
    - The tool cache now contains **two** recent CodeQL versions (previously **one**).
    - Each CodeQL version is located under a directory named after the release date and version number, e.g. CodeQL 2.11.6 is now located under `CodeQL/2.11.6-20221211/x64/codeql` (previously `CodeQL/0.0.0-20221211/x64/codeql`).
- The maximum number of [SARIF runs](https://docs.github.com/en/code-security/code-scanning/integrating-with-code-scanning/sarif-support-for-code-scanning#run-object) per file has been increased from 15 to 20 for users uploading SARIF files to GitHub.com. This change will help ensure that Code Scanning can process SARIF files generated by third-party tools that have many runs. See the [GitHub API documentation](https://docs.github.com/en/rest/code-scanning#upload-an-analysis-as-sarif-data) for a list of all the limits around uploading SARIF. This change will be released to GitHub Enterprise Server as part of GHES 3.9.
- Update default CodeQL bundle version to 2.12.1. [#1498](https://github.com/github/codeql-action/pull/1498)
- Fix a bug that forced the `init` Action to run for at least two minutes on JavaScript. [#1494](https://github.com/github/codeql-action/pull/1494)

## 2.1.39 - 18 Jan 2023

- CodeQL Action v1 is now deprecated, and is no longer updated or supported. For better performance, improved security, and new features, upgrade to v2. For more information, see [this changelog post](https://github.blog/changelog/2023-01-18-code-scanning-codeql-action-v1-is-now-deprecated/). [#1467](https://github.com/github/codeql-action/pull/1466)
- Python automatic dependency installation will no longer fail for projects using Poetry that specify `virtualenvs.options.no-pip = true` in their `poetry.toml`. [#1431](https://github.com/github/codeql-action/pull/1431)
- Avoid printing a stack trace and error message when the action fails to find the SHA at the
  current directory. This will happen in several non-error states and so we now avoid cluttering the
  log with this message. [#1485](https://github.com/github/codeql-action/pull/1485)

## 2.1.38 - 12 Jan 2023

- Update default CodeQL bundle version to 2.12.0. [#1466](https://github.com/github/codeql-action/pull/1466)

- Update default CodeQL bundle version to 2.11.5. [#1412](https://github.com/github/codeql-action/pull/1412)
- Add a step that tries to upload a SARIF file for the workflow run when that workflow run fails. This will help better surface failed code scanning workflow runs. [#1393](https://github.com/github/codeql-action/pull/1393)
- Python automatic dependency installation will no longer consider dependency code installed in venv as user-written, for projects using Poetry that specify `virtualenvs.in-project = true` in their `poetry.toml`. [#1419](https://github.com/github/codeql-action/pull/1419)

## 2.1.35 - 01 Dec 2022

No user facing changes.

## 2.1.34 - 25 Nov 2022

- Update default CodeQL bundle version to 2.11.4. [#1391](https://github.com/github/codeql-action/pull/1391)
- Fixed a bug where some the `init` action and the `analyze` action would have different sets of experimental feature flags enabled. [#1384](https://github.com/github/codeql-action/pull/1384)

## 2.1.33 - 16 Nov 2022

- Go is now analyzed in the same way as other compiled languages such as C/C++, C#, and Java. This completes the rollout of the feature described in [CodeQL Action version 2.1.27](#2127---06-oct-2022). [#1322](https://github.com/github/codeql-action/pull/1322)
- Bump the minimum CodeQL bundle version to 2.6.3. [#1358](https://github.com/github/codeql-action/pull/1358)

## 2.1.32 - 14 Nov 2022

- Update default CodeQL bundle version to 2.11.3. [#1348](https://github.com/github/codeql-action/pull/1348)
- Update the ML-powered additional query pack for JavaScript to version 0.4.0. [#1351](https://github.com/github/codeql-action/pull/1351)

## 2.1.31 - 04 Nov 2022

- The `rb/weak-cryptographic-algorithm` Ruby query has been updated to no longer report uses of hash functions such as `MD5` and `SHA1` even if they are known to be weak. These hash algorithms are used very often in non-sensitive contexts, making the query too imprecise in practice. For more information, see the corresponding change in the [github/codeql repository](https://github.com/github/codeql/pull/11129). [#1344](https://github.com/github/codeql-action/pull/1344)

## 2.1.30 - 02 Nov 2022

- Improve the error message when using CodeQL bundle version 2.7.2 and earlier in a workflow that runs on a runner image such as `ubuntu-22.04` that uses glibc version 2.34 and later. [#1334](https://github.com/github/codeql-action/pull/1334)

## 2.1.29 - 26 Oct 2022

- Update default CodeQL bundle version to 2.11.2. [#1320](https://github.com/github/codeql-action/pull/1320)

## 2.1.28 - 18 Oct 2022

- Update default CodeQL bundle version to 2.11.1. [#1294](https://github.com/github/codeql-action/pull/1294)
- Replace uses of GitHub Actions command `set-output` because it is now deprecated. See more information in the [GitHub Changelog](https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/). [#1301](https://github.com/github/codeql-action/pull/1301)

## 2.1.27 - 06 Oct 2022

- We are rolling out a feature of the CodeQL Action in October 2022 that changes the way that Go code is analyzed to be more consistent with other compiled languages like C/C++, C#, and Java. You do not need to alter your code scanning workflows. If you encounter any problems, please [file an issue](https://github.com/github/codeql-action/issues) or open a private ticket with GitHub Support and request an escalation to engineering.

## 2.1.26 - 29 Sep 2022

- Update default CodeQL bundle version to 2.11.0. [#1267](https://github.com/github/codeql-action/pull/1267)

## 2.1.25 - 21 Sep 2022

- We will soon be rolling out a feature of the CodeQL Action that stores some information used to make future runs faster in the GitHub Actions cache. Initially, this will only be enabled on JavaScript repositories, but we plan to add more languages to this soon. The new feature can be disabled by passing the `trap-caching: false` option to your workflow's `init` step, for example if you are already using the GitHub Actions cache for a different purpose and are near the storage limit for it.
- Add support for Python automatic dependency installation with Poetry 1.2 [#1258](https://github.com/github/codeql-action/pull/1258)

## 2.1.24 - 16 Sep 2022

- Update default CodeQL bundle version to 2.10.5. [#1240](https://github.com/github/codeql-action/pull/1240)

## 2.1.22 - 01 Sep 2022

- Downloading CodeQL packs has been moved to the `init` step. Previously, CodeQL packs were downloaded during the `analyze` step. [#1218](https://github.com/github/codeql-action/pull/1218)
- Update default CodeQL bundle version to 2.10.4. [#1224](https://github.com/github/codeql-action/pull/1224)
- The newly released [Poetry 1.2](https://python-poetry.org/blog/announcing-poetry-1.2.0) is not yet supported. In the most common case where the CodeQL Action is automatically installing Python dependencies, it will continue to install and use Poetry 1.1 on its own. However, in certain cases such as with self-hosted runners, you may need to ensure Poetry 1.1 is installed yourself.

## 2.1.21 - 25 Aug 2022

- Update default CodeQL bundle version to 2.10.1.  [#1143](https://github.com/github/codeql-action/pull/1143)

## 2.1.16 - 13 Jul 2022

- You can now quickly debug a job that uses the CodeQL Action by re-running the job from the GitHub UI and selecting the "Enable debug logging" option. [#1132](https://github.com/github/codeql-action/pull/1132)
- You can now see diagnostic messages produced by the analysis in the logs of the `analyze` Action by enabling debug mode. To enable debug mode, pass `debug: true` to the `init` Action, or [enable step debug logging](https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/enabling-debug-logging#enabling-step-debug-logging). This feature is available for CodeQL CLI version 2.10.0 and later. [#1133](https://github.com/github/codeql-action/pull/1133)

## 2.1.15 - 28 Jun 2022

- CodeQL query packs listed in the `packs` configuration field will be skipped if their target language is not being analyzed in the current Actions job. Previously, this would throw an error. [#1116](https://github.com/github/codeql-action/pull/1116)
- The combination of python2 and poetry is no longer supported. See <https://github.com/actions/setup-python/issues/374> for more details. [#1124](https://github.com/github/codeql-action/pull/1124)
- Update default CodeQL bundle version to 2.10.0. [#1123](https://github.com/github/codeql-action/pull/1123)

- Beware that the CodeQL build tracer in this release (and in all earlier releases) is incompatible with Windows 11 and Windows Server 2022. This incompatibility affects database extraction for compiled languages: cpp, csharp, go, and java. As a result, analyzing these languages with the `windows-latest` or `windows-2022` Actions virtual environments is currently unsupported. If you use any of these languages, please use the `windows-2019` Actions virtual environment or otherwise avoid these specific Windows versions until a new release fixes this incompatibility.
