Recent changes

More wikis are now testing visual editor section editing for mobile users. You can read more.
Admins on French and Polish Wikipedia can block someone from editing a page or a namespace. If your wiki wants to get these blocks before they are available to all wikis, you can tell the developers. [1][2]

Problems

You will be able read but not edit most wikis for 30 minutes on 11 April at 05:00 (UTC). This is because of a hardware problem. You can see a list of the affected wikis. [3]
A map update caused some problems on 29 March and 30 March. It was rolled back. [4]
Pages on some Wikivoyages had problems with the top headline. This has been fixed. [5]

Changes later this week

When you add an edit summary the VisualEditor will search your recent edit summaries in case you want to re-use one. This works in both the visual and wikitext modes on desktop. It also works on the mobile site. [6]
The Wikimedia wikis will get a URL shortener. This will work from 11 April. You can read more. [7]
The {{REVISIONID}} magic word will no longer work. This is for performance reasons. When you preview a page it will return "" (empty string). When you read a page it will return "-" (dash). For now this will only affect content namespaces. [8]
The new version of MediaWiki will be on test wikis and MediaWiki.org from 9 April. It will be on non-Wikipedia wikis and some Wikipedias from 10 April. It will be on all wikis from 11 April (calendar).

Meetings

You can join the technical advice meeting on IRC. During the meeting, volunteer developers can ask for advice. The meeting will be on 10 April at 15:00 (UTC). See how to join.

Future changes

You will be able to preview references. This means that when you hover over the link you will get a popup that shows you a preview of the reference. It will work much like page previews. This is so you don't have to go to the bottom of the page to see a reference. This will now be available as a beta feature on German and Arabic Wikipedia. [9][10]
The Wikidata JSON output will change. Empty containers will be serialised as empty objects. This is a breaking change that will affect tools that use JSON outputs and APIs. It will happen on 30 April. You can read more and see how to test your code.
