I try to send out these emails on Tuesdays, apologies for the delay.

Over the next few days, wmf12 will be deployed to WMF wikis. We mostly worked on small fixes this week and on the cawiki deployment, so there aren't that many exciting things in wmf12. Some of the more noteworthy things new in wmf12 are:

Timestamp link in grouped recent changes now points somewhere useful
Topic history pages are now full-width

wmf12 follows the standard deployment timeline, which is as follows:

Tuesday 11am-1pm PDT: deployment to test wikis ("group 0"); for Flow, these are testwiki, test2wiki and mediawiki.org
Wednesday 11am-1pm PDT: deployment to non-Wikipedia wikis ("group 1"); for Flow, these are meta, officewiki and wikidata
Thursday 11am-1pm PDT: deployment to Wikipedias ("group 2"); for Flow, these are the English, French, Hebrew, Portugese, Catalan, Telugu, Russian, Punjabi and Chinese Wikipedias

In non-wmf12-related news, we also enabled Flow in the Viquipèdia Discussió namespace on Catalan Wikipedia yesterday. This happened between 21:55 and 22:15 UTC on June 30.
