Hello all,
I just wanted to send a note about a reference doc on the MediaWiki wiki on backporting bug fixes: https://www.mediawiki.org/wiki/Backporting_Fixes
It addresses the difference between backports to stable releases versus the code on the WMF cluster (as well as the special process for security related bugs).
Of note:
We now have backport "flags" in bugzilla to track the backport process. There is one for stable releases ("Backport_to_Stable") and one for the WMF cluster ("Backport_WMF").
I hope this can help to clarify some confusion around the backporting process.
