Changes this week
You will be able to use <chem> to write chemical formulas in the visual editor. Previously this only worked in the wikitext editor. 
The new version of MediaWiki will be on test wikis and MediaWiki.org from 28 February. It will be on non-Wikipedia wikis and some Wikipedias from 1 March. It will be on all wikis from 2 March (calendar).
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 28 February at 20:00 (UTC). See how to join.
You can soon upload 3D files to Commons. The file formats are AMF and STL. The plan is for this to work later this week but it could be later. 
The name "Wikipedia" will be more obvious at the top of the page when you read Wikipedia in the mobile view. This is because many readers don't realize they are on Wikipedia.
