 # CodeQL Action - Copilot Instructions
 
+The CodeQL Action is used in GitHub Actions workflows to run CodeQL scans using the CodeQL CLI.
+
+## Overview
+
+- The repository contains two TypeScript projects.
+- The main TypeScript codebase is in the `src` directory, with accompanying unit tests in `.test.ts` files in the same directory.
+- The main codebase is compiled to bundled JavaScript code, which is also contained in the repository in the `lib` directory.
+- A secondary TypeScript codebase with scripts that are only used for development purposes or by CI is in the `pr-checks` directory. This codebase is not compiled to bundled JavaScript. It is executed directly with `tsx`, which handles compilation internally.
+
+## Review instructions
+
+- When wording review comments, be helpful and friendly. Assume that the PR author has written the code with the best of intentions. Word your comments constructively as suggestions for improvements. Do not word suggestions as commands.
+- If you want to comment on a change that you believe will fail a CI check, do not present the CI failure you expect as a fact. Instead, write that you think a change "may" lead to a failure in CI. Suggest that, if such a failure manifests, the changes you are commenting on may be the place responsible for the failure and are worth looking at.
+- If a suggestion you make is suitable for a follow-up, such as a refactoring that doesn't change the behaviour or fixing a typo in a comment, mention that it can be addressed in a later PR rather than blocking this one.
+- If a change is a net improvement, for example because it improves on an existing limitation of existing code, do not complain about pre-existing problems that remain. You may comment on them, but you should make it clear that the thing you are commenting on is not new by writing e.g. "Not new in this PR, but [..]" followed by your description of the issue and a suggestion that it could be improved at the same time with e.g. "Consider whether this is worth addressing as part of this PR as well."
+
 ## Generated code
 
-The CodeQL Action is written in TypeScript and compiled to JavaScript. Both the TypeScript sources and the **generated** JavaScript code are contained in this repository. The TypeScript sources are contained in the `src` directory and the JavaScript code is contained in the `lib` directory. A GitHub Actions workflow checks that the JavaScript code in `lib` is up-to-date. Therefore, you should not review any changes to the contents of the `lib` folder and it is expected that the JavaScript code in `lib` closely mirrors the TypeScript code it is generated from.

The secondary TypeScript codebase has sources in the `pr-checks` directory, which are executed directly with `tsx` and not compiled to JavaScript in the `lib` folder.
 
 GitHub Actions workflows in the `.github/workflows` directory whose filenames start with two underscores (e.g. `__all-platform-bundle.yml`) are automatically generated using the `pr-checks/sync.sh` script from template files in the `pr-checks/checks` directory. Therefore, you do not need to review files in the `.github/workflows` directory that start with two underscores. However, you should review changes to the `pr-checks` directory as well as workflows in the `.github/workflows` directory that do not start with underscores.
 
 ## Release process
 
+Changes that are merged to the `main` branch are not used in production straight away. Instead, changes from `main` must first be released using the release process, which has to be manually triggered by a staff member. Therefore, it is possible for further changes to be made to the code after some changes have been merged to `main` but before they are released. Once the release process automation is started, a series of PRs are automatically generated:
+
 - A release-PR is a PR which matches all of the following patterns:
+
   - PR title starts with the exact prefix: `Merge main into releases/v`
     - Equivalent regex: `^Merge main into releases\/v`
   - AND head (source) branch matches the update-branch pattern:

+# Merging release, mergeback, and backport PRs
+
+The release process creates a cascade of PRs (`main` → `releases/vN`, then
+`releases/vN` → `main` mergeback, then `releases/vN` → `releases/v(N-1)`
+backport). These PRs reliably touch `CHANGELOG.md`, `src/defaults.json` /
+`lib/defaults.json` (bundle/CLI version bump), and `src/api-compatibility.json`.
+
+Such PRs **must be merged with a merge commit**. Never squash or rebase, as
+that breaks the branch linkage the release automation relies on.
+
+When arming auto-merge on these PRs, use `--merge` (e.g. `gh pr merge --merge`),
+not `--squash` or `--rebase`.

 See the [releases page](https://github.com/github/codeql-action/releases) for the relevant changes to the CodeQL CLI and language packs.
 
-## [UNRELEASED]
+## 4.38.2 - 24 Sept 2026
+
+- Update default CodeQL bundle version to [2.27.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.27.1). [#4160](https://github.com/github/codeql-action/pull/4160)
+
+## 4.38.1 - 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
+
+- 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)
+
+## 4.37.9 - 26 Aug 2026
+
+- Update default CodeQL bundle version to [2.26.4](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.4). [#4106](https://github.com/github/codeql-action/pull/4106)
+
+## 4.37.8 - 21 Aug 2026
+
+No user facing changes.
+
+## 4.37.7 - 13 Aug 2026
+
+- Update default CodeQL bundle version to [2.26.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.26.3). [#4085](https://github.com/github/codeql-action/pull/4085)
+
+## 4.37.6 - 04 Aug 2026
+
+- Changed the default filepath for the new remote file address format that was introduced in CodeQL Action 4.37.0 / 3.37.0 to `.github/codeql-config.yml` to align it with the suggested path that is used elsewhere. [#4070](https://github.com/github/codeql-action/pull/4070)
+
+## 4.37.5 - 03 Aug 2026
+
+- 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
+
+- 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)
+
+## 4.37.3 - 22 Jul 2026
+
+No user facing changes.
+
+## 4.37.2 - 21 Jul 2026
+
+- 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)
+
+## 4.37.1 - 16 Jul 2026
 
 - _Upcoming breaking change_: Add a deprecation warning for customers using CodeQL version 2.20.6 and earlier. These versions of CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise Server 3.16, and will be unsupported by the next minor release of the CodeQL Action. [#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)

This mergeback pull request incorporates the changelog updates into `main`, tags the release using the merge commit of the "Merge main into releases/v3" pull request, and bumps the patch version of the CodeQL Action.
