There was no new MediaWiki version last week. Changes that were planned to happen last week will happen this week instead. This is because of a bug that made saving pages take longer time. 
Changes this week
After February 23, you can use Wikidata for inter-language links on Wikiversity. 
You can join the next meeting with the VisualEditor team. During the meeting, you can tell developers which bugs you think are the most important. The meeting will be on 23 February at 20:00 (UTC). See how to join.
