Changes this week
Wikimedia pages will now be better at showing pictures when you share them on social media. The descriptions will be different too. You can see an example of before and after. 
There are some changes to the OOjs UI. Some old functions will not work anymore or not work as they used to. This could be a breaking change. 
The new version of MediaWiki will be on test wikis and MediaWiki.org from 7 February. It will be on non-Wikipedia wikis and some Wikipedias from 8 February. It will be on all wikis from 9 February (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 7 February at 20:00 (UTC). See how to join.
Tidy will be replaced later this year. Instead, the HTML 5 parsing algorithm will be used to clean up bad HTML in wikitext. This will cause problems on a number of wikis. They need to be fixed first. You can see if your wiki still has something to fix here for one of the HTML problems. This list does not cover all problems. You can read about more problems.
