Contrary to popular rumor, I am by no means inactive - just a bit busy. If your matter is urgent, please email me or poke me on IRC; otherwise, leave a message here and I'll get back to you as quickly as I can. Many thanks.
Lots of improvements around MixNMatch. It has a new catalog overview page. ~340K IDs have been matched so far with it and it now has an FAQ for institutions wanting to get their identifiers linked in Wikidata

Changes this week
The new version of MediaWiki has been on test wikis and MediaWiki.org since March 18. It will be on non-Wikipedia wikis from March 24. It will be on all Wikipedias from March 25 (calendar).
The text of a reference is now more visible when you click on it. It has a blue background. Many wikis already have the blue color. Those wikis can now remove it from their CSS page. 
VisualEditor is now much faster. For many users it is now at least as fast as the wikitext editor. 
When you add a list of references in VisualEditor, you now see it right away. You can still change its group by editing it. 
You can read the notes from the last meeting with the VisualEditor team.
You can join the next weekly meeting with the VisualEditor team. During the meetings you can tell developers which bugs are the most important. The meeting will be on March 25 at 19:00 (UTC). See how to join.
Talk pages using "LiquidThreads" on mediawiki.org will soon use the new system.
