>> 1504: The Skara tooling includes support for backports. [The official Skara documentation](https://wiki.openjdk.java.net/display/SKARA/Backports) describes in detail how to work with the tooling to create backport PRs on GitHub or using the CLI tools. As described in the documentation, the [`/backport`](https://wiki.openjdk.java.net/display/SKARA/Commit+Commands#CommitCommands-/backport) command can be used on a commit (not a PR!) to create the backport PR. If a backport PR is manually created, set the title to `Backport <original commit hash>`.

This ensures that the the bots will recognize it as a backport as opposed to a fix specifically targetting an older release only. One can tell whether or not the bots recognized a PR as a backport by the `backport` label being added if it is being recognized."
