Any change going into the release stabilization repository is likely to be desired in mainline as well. When making a change intended both for the stabilization release and the mainline repository, you should always create your pull request targeting the mainline repository first, and then, once the pull request is integrated, backport the resulting commit to the release stabilization repository. For bugfixes that are **only** applicable to the release stablization repository, regular pull requests targeting the stabilization fork should be created.

I know you already integrated this, but I noticed a typo in the last sentence: s/stablization/stabilization
