Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.

Recent changes

  • Octicons-tools.svg EventStreams is a new way to show activity on Wikimedia wikis. For now it works with the recent changes feed. It will do more things later. It will replace RCStream. Tools that use RCStream should move to EventStreams before 7 July. [1]


  • The Firefox add-on Firefogg can cause problems with the Upload Wizard. This will not be fixed, because Firefox will not support Firefogg in the future. The Upload Wizard will no longer work with Firefogg. [2]
  • Tool Labs and Wikimedia Labs databases will be under maintenance on 15 February. This will start at 17:00 (UTC) and last for about six hours. Some tools could have problems during or after this. [3]

Changes this week

  • The TwoColConflict extension is a new way to solve edit conflicts. It makes it easier to copy and paste the relevant text to the text field. It will come to Meta and German Wikipedia this week. It is already available on MediaWiki.org. It will come to more wikis later. [4]
  • Octicons-sync.svg The new version of MediaWiki will be on test wikis and MediaWiki.org from 14 February. It will be on non-Wikipedia wikis and some Wikipedias from 15 February. It will be on all wikis from 16 February (calendar).


  • Octicons-sync.svg 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 14 February at 20:00 (UTC). See how to join.

Future changes

  • Page Previews will be turned on for logged-out users on the Catalan, Greek, Russian, and Italian Wikipedias in the middle of February. Page Previews shows readers a short part of a linked article when they rest their mouse pointer on the link. This is to help them understand what it is about without leaving the article they are reading. Page Previews used to be called Hovercards. It will come to more wikis later this spring. [5]
  • Octicons-tools.svg The Developer Wishlist is a list where developers prioritize tools they need. The voting closes at 14 February 23:59 (UTC). This process is only for developers.
