+- 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 It has been superseded by a new `analysis-kinds` input, which is part of the same internal experiment.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.

     You can start a release by triggering this workflow via [workflow dispatch](https://github.com/github/codeql-action/actions/workflows/update-release-branch.yml).
 1. The workflow run will open a pull request titled "Merge main into releases/v3". Follow the steps on the checklist in the pull request. Once you've checked off all but the last two of these, approve the PR and automerge it.
-1. When the "Merge main into releases/v3" pull request is merged into the `releases/v3` branch, a mergeback pull request to `main` will be automatically created. 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.

 ## Keeping the PR checks up to date (admin access required)
 
-Since the `codeql-action` runs most of its testing through individual Actions workflows, there are over two hundred jobs that need to pass in order for a PR to turn green.

+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 [update-required-checks.sh](.github/workflows/script/update-required-checks.sh) script:
 
-1. By default, this script retrieves the checks from the latest SHA on `main`, so make sure that your `main` branch is up to date.
-2. Run the script. If there's a reason to, you can pass in a different SHA as a CLI argument.
-3. After running, go to the [branch protection rules settings page](https://github.com/github/codeql-action/settings/branches) and validate that the rules for `main`, `v3`, and any other currently supported major versions have been updated.
+- If you run the script without an argument, it will retrieve the set of workflows that ran for the latest commit on `main`. Make sure that your local `main` branch is up to date before running the script.
+- You can specify a commit SHA as argument to retrieve the set of workflows for that commit instead. You will likely want to use this if you have a PR that removes or adds PR checks.

 Note that any updates to checks on `main` need to be backported to all currently supported major version branches, in order to maintain the same set of names for required checks.
