In one week, we (Markus Glaser and I) plan to create a REL1_22 branch for the 1.22.0 that we have scheduled for 6 weeks from now, no later than November 29th.
In order to facilitate this, please make sure anything you want in 1.22 is ready this week. We'll probably do a couple merges from the WMF branches in the process of making release candidates, but I'd like to have any major changes in within the next week.
During the period leading up the release, please consider using the "critical" severity level ensure any release critical bugs are logged and tracked.
In addition, please look over https://www.mediawiki.org/wiki/MediaWiki_1.22 and help update it since it will be used in our release announcement.
Thanks,
Mark.
