-## 3.36.0 - 22 May 2026
+## [UNRELEASED]
 
 - _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)
 
-## 3.35.5 - 15 May 2026
+## 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.

 - 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)

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)

   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.

 - 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).

   - 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.

 - _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.
