+          Thanks for your contribution! Unfortunately we can't accept PRs directed at release branches. We make patches to the bugfix branches and only later do we push them out as releases.
+
+          Please redo this PR starting with the `bugfix-2.0.x` branch and be careful to target `bugfix-2.0.x` when resubmitting the PR.
+
+          It may help to set your fork's default branch to `bugfix-2.0.x`.
+
+          See [this page](http://marlinfw.org/docs/development/getting_started_pull_requests.html) for full instructions.
