 See the [releases page](https://github.com/github/codeql-action/releases) for the relevant changes to the CodeQL CLI and language packs.
 
-## [UNRELEASED]
+## 3.39.2 - 03 Nov 2026
 
-No user facing changes.
+- Update default CodeQL bundle version to [2.27.4](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.4). [#4284](https://github.com/github/codeql-action/pull/4284)
+- _Upcoming breaking change_: CodeQL version 2.22.3 and earlier were discontinued on 16 October 2026 alongside GitHub Enterprise Server 3.18, and will be unsupported by the next minor release of the CodeQL Action. Added a deprecation warning for customers using these versions of CodeQL. [#4266](https://github.com/github/codeql-action/pull/4266)
+- Starting with macOS 27 and Xcode 27, traced analyses are unsupported. See [this blog post for more information](https://github.blog/changelog/2026-10-19-codeql-changes-for-macos-27-xcode-27-and-swift-6-4/). The CodeQL Action will now try to identify if a workflow is about to perform a traced analysis on version 27 or above of macOS or Xcode. If so, the CodeQL Action will emit a corresponding warning that will also be visible on the [Tool Status Page](https://docs.github.com/en/code-security/how-tos/find-and-fix-code-vulnerabilities/manage-your-configuration/use-the-tools-status-page-for-code-scanning). This check will be rolled out following this release of the CodeQL Action. [#4221](https://github.com/github/codeql-action/pull/4221)
+- The undocumented TRAP cache cleanup feature that could be enabled using the `CODEQL_ACTION_CLEANUP_TRAP_CACHES` environment variable has been removed, as announced in the release notes for CodeQL Action 4.35.2. The `analyze` Action now warns if this environment variable is set. If you used TRAP cache cleanup to limit Actions cache usage, we recommend disabling TRAP caching by passing the `trap-caching: false` input to the `init` Action. [#4243](https://github.com/github/codeql-action/pull/4243)

+- Update default CodeQL bundle version to [2.27.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.3). [#4256](https://github.com/github/codeql-action/pull/4256)
+
+## 3.39.0 - 15 Oct 2026
 
 - _Breaking change_: Bump the minimum required CodeQL bundle version to 2.20.7. [#4205](https://github.com/github/codeql-action/pull/4205)
 - The `codeql-action/analyze` step now validates that a correct argument for the `checkout_path` input has been provided. The `checkout_path` input must be set to the path where the repository that is being analyzed is checked out at on the runner, if that path is something other than the workspace root. If the path does not point to a repository checkout or is different from the path that was used by `codeql-action/init`, then the CodeQL Action now produces a warning. [#4148](https://github.com/github/codeql-action/pull/4148)
 - Resolved an issue with third-party caching implementations that prevented caches from being restored correctly. [#4206](https://github.com/github/codeql-action/pull/4206)
 - The `codeql-action/start-proxy` step that is used in Code Scanning Default Setup now finds CodeQL releases using the same logic as `codeql-action/init`. This primarily benefits customers who are using GitHub instances other than `github.com` where the `codeql-action/start-proxy` step may previously have been unable to locate recent releases and ended up using outdated versions of the private registry authentication proxy as a result.

 - _Upcoming breaking change_: CodeQL version 2.21.2 and earlier were discontinued on 24 September 2026 alongside GitHub Enterprise Server 3.17, and will be unsupported by the next minor release of the CodeQL Action. Added a deprecation warning for customers using these versions of CodeQL. [#4188](https://github.com/github/codeql-action/pull/4188)
 - Update default CodeQL bundle version to [2.27.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.2). [#4203](https://github.com/github/codeql-action/pull/4203)
 - Fixed a bug where the decision of whether to use a per-language bundle did not account for custom configurations that reference queries outside of compiled CodeQL packs. This issue was caught during internal testing and did not affect any customer repositories. We will resume the roll out of per-language bundles in the coming weeks. [#4184](https://github.com/github/codeql-action/pull/4184)
 
-## 4.38.2 - 24 Sept 2026

+## 3.38.1 - 18 Sept 2026
 
 - The CodeQL Action now has experimental support for CodeQL releases for which per-language bundles are available. Per-language bundles support analysis for a single language and are therefore smaller than the combined bundles that allow analysis for all supported languages. As a result, per-language bundles take up less space on disk and are faster to download. We expect to roll this change out to everyone in the coming weeks. [#4146](https://github.com/github/codeql-action/pull/4146)
 
-## 4.38.0 - 09 Sept 2026
+## 3.38.0 - 09 Sept 2026
 
 - On GitHub-hosted runners, the CodeQL Action now deletes unused CodeQL bundles from the toolcache before downloading a different bundle, which frees up disk space for the analysis. We expect to roll this change out to everyone in September. [#4124](https://github.com/github/codeql-action/pull/4124)
 - The CodeQL Action now supports CodeQL releases that are compatible with Linux Arm64 and downloads the native `linux-arm64` CodeQL bundle when available. [#4072](https://github.com/github/codeql-action/pull/4072)
 - Update default CodeQL bundle version to [2.27.0](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.0). [#4129](https://github.com/github/codeql-action/pull/4129)

 - Fixed a bug where a network error while streaming the download of the CodeQL bundle could terminate the `init` Action instead of falling back to downloading the bundle before extracting it. [#4061](https://github.com/github/codeql-action/pull/4061)
 
-## 4.37.4 - 29 Jul 2026
+## 3.37.4 - 29 Jul 2026
 
 - This version of the CodeQL Action adds support for the `tools` input for the `codeql-action/init` step to be specified using a `github-codeql-tools` [repository property](https://docs.github.com/en/organizations/managing-organization-settings/managing-custom-properties-for-repositories-in-your-organization). This feature will gradually be rolled out following the release of this version. Once rolled out, this allows for the CodeQL CLI version that is used in GitHub-managed workflows, such as Default Setup, to be set to a custom value. For example, customers who run into issues with rate limits when a new CodeQL CLI version is released can set the value to `toolcache` to always use the CodeQL CLI version that is available in the runner toolcache. For Advanced Setup workflows, the value provided for `tools` in the workflow definition always takes precedence unless the value of the repository property starts with `!`. [#4037](https://github.com/github/codeql-action/pull/4037)
 - Update default CodeQL bundle version to [2.26.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.2). [#4051](https://github.com/github/codeql-action/pull/4051)

 - The new address format for the `config-file` input that was introduced in CodeQL Action 4.37.0 is now enabled by default. In addition to the format described there, the `remote=` prefix can now be used to explicitly indicate that the input refers to a remote file. All previous input formats continue to be accepted as well. [#4023](https://github.com/github/codeql-action/pull/4023)
 - The CodeQL Action can now make use of [configured private 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) in Default Setup to retrieve CodeQL configuration files from remote repositories that require authentication. This will allow customers to store their CodeQL configuration in a single repository that can then be referenced by Default Setup workflows in other repositories. We expect to roll this and other, related changes out to everyone in July. [#4007](https://github.com/github/codeql-action/pull/4007)

 - _Upcoming breaking change_: Add a deprecation warning for customers using CodeQL version 2.20.6 and earlier.

[#3956](https://github.com/github/codeql-action/pull/3956)
 - Update default CodeQL bundle version to [2.26.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.1). [#4019](https://github.com/github/codeql-action/pull/4019)

 - In addition to the existing input format, the `config-file` input for the `codeql-action/init` step will soon support a new `[owner/]repo[@ref][:path]` format. All components except the repository name are optional. If omitted, `owner` defaults to the same owner as the repository the analysis is running for, `ref` to `main`, and `path` to `.github/codeql-action.yaml`. Support for this format ships in this version of the CodeQL Action, but will only be enabled over the coming weeks. [#3973](https://github.com/github/codeql-action/pull/3973)

 - 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.

 - 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.

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.
