Wikimedia Commons will have better access to Wikidata. They can use data from any page on Wikidata on any page on Commons. This will happen on April 26.
It will be easier to choose if you want to watch files you have uploaded with the upload wizard.
The new version of MediaWiki will be on test wikis and MediaWiki.org from April 26. It will be on non-Wikipedia wikis and some Wikipedias from April 27. It will be on all wikis from April 28 (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 April 26 19:00 (UTC). See how to join.
The "Gravar página" button when you edit will be called "Publish" instead. This is to help new editors understand what it does. It already works like this on some wikis.
