            Please ensure that the four packages below work properly.
            Once that's done, replace this text with the changelog, un-draft the release, and update the `release` branch.
            By the way, if you forgot to update `include/version.hpp`, RGBASM's version test is gonna fail in the tag's regression testing! (Use `git push --delete origin <tag>` to delete it)
          draft: true # Don't publish the release quite yet...
