Lucie and Charlie handed in their Bachelor theses on the Article Placeholder and Editing Wikidata from Wikipedia. Work on both topics will continue. We'll publish both theses soon. A big congrats to both of them!
Property:P1367 ("BBC Your Paintings artist-ID") has become "Art UK artist identifier". Identifier values were replaced.
The number of claims on each item is to be included in the "page property" database table. For some items where it had been missing, it was recently added. This leads to improved coverage by database reports: without claims by site.
Mix'n'match has new catalogs: Artists of the Nationalmuseum in Sweden and Encyclopædia Britannica
The in other projects sidebar has graduated from beta features and is now turned on on all projects except Dutch Wikipedia. (They have their own hack.) This closes a wish that has been around since 2004 \o/ (phabricator:T2708)
Added a new identifiers section in items. Everything with datatype external identifier goes there now. Once we have all identifiers converted items should be easier to scan and understand because of the clearer structure.
We have a patch upcoming that should reduce loading time of items with a lot of sitelinks by 25%
Fixed a bug where you could not add statements with external identifier or mathematical expression datatype (phabricator:T127095)
More groundwork for Commons (making it possible to have more entities than just items and properties)
