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


  • The block log sometimes showed blocks as being much longer than they were. This has now been fixed. [1]

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[2]
  • Octicons-tools.svg 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. [3]
  • Octicons-sync.svg 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).


  • 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 7 February at 20:00 (UTC). See how to join.

Future changes

  • Octicons-tools.svg 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[4][5]
