The Push Queue is mostly a normal queue, but it has some special logic to merge push requests for each given proxy. This results in each proxy having 0 or 1 outstanding push requests; if additional updates come in the existing push request is just expanded.

Another job polls this queue and triggers each client to start a push.

4. Tag the release and push to GitHub.

    ```
    git commit -am "Prepare for release $RELEASE_VERSION."
    git tag -a parent-$RELEASE_VERSION -m "Version $RELEASE_VERSION"
    git push && git push --tags
    ```

5. Wait for [GitHub Actions][github_actions] to start the publish job.

6. Prepare for ongoing development and push to GitHub.

    ```
    sed -i "" \
