I am attempting to update an outdated wiki but REL1_39 is missing from the extensions repository, and in fact anything after 1.35 isn't there either. Same issue affects the Skins repository too. See: * https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/skins * https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/+refs

Not having branched releases matching between the groups will cause compatibility issues.

Can we please get the missing branches made?
