 :::warning Do not fork outdated forks
 Fixes should not be applied by starting with a fork of an already approved fork. For example, when an issue is reported with a JavaScript version of a kata, it should be fixed by forking the current state of the kata, not by forking the original, approved JavaScript translation or the most recent JavaScript translation. The kata may have been modified after the translation was published and approved, and forking an old fork can revert changes applied afterward.
