 ## [UNRELEASED]
 
-No user facing changes.
+- _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)
+
+## 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)

 Since the `codeql-action` runs most of its testing through individual Actions workflows, there are over two hundred required jobs that need to pass in order for a PR to turn green. It would be too tedious to maintain that list manually. You can regenerate the set of required checks automatically by running the [sync-checks.ts](pr-checks/sync-checks.ts) script:
 
-- At a minimum, you must provide an argument for the `--token` input. For example, `--token "$(gh auth token)"` to use the same token that `gh` uses. If no token is provided or the token has insufficient permissions, the script will fail.
+- At a minimum, you must provide a token with permissions to update branch protection rules. For example, `gh auth token | pr-checks/sync-checks.ts --token-stdin` uses the same token that `gh` uses. You can also set the `GH_TOKEN` or `GITHUB_TOKEN` environment variable. If no token is provided or the token has insufficient permissions, the script will fail.
 - By default, the script performs a dry run and outputs information about the changes it would make to the branch protection rules. To actually apply the changes, specify the `--apply` flag.
 - If you run the script without any other arguments, it will retrieve the set of workflows that ran for the latest commit on `main`.
 - You can specify a different git ref with the `--ref` input. You will likely want to use this if you have a PR that removes or adds PR checks. For example, `--ref "some/branch/name"` to use the HEAD of the `some/branch/name` branch.
