Tech News: 2025-03
Latest tech news from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.
Weekly highlight
- The Single User Login system is being updated over the next few months. This is the system which allows users to fill out the login form on one Wikimedia site and get logged in on all others at the same time. It needs to be updated because of the ways that browsers are increasingly restricting cross-domain cookies. To accommodate these restrictions, login and account creation pages will move to a central domain, but it will still appear to the user as if they are on the originating wiki. The updated code will be enabled this week for users on test wikis. This change is planned to roll out to all users during February and March. See the SUL3 project page for more details and a timeline.
Updates for editors
- On wikis with PageAssessments installed, you can now filter search results to pages in a given WikiProject by using the
inproject:keyword. (These wikis: Arabic Wikipedia, English Wikipedia, English Wikivoyage, French Wikipedia, Hungarian Wikipedia, Nepali Wikipedia, Turkish Wikipedia, Chinese Wikipedia) [1] - One new wiki has been created: a Wikipedia in Tigre (
w:tig:) [2] 
View all 35 community-submitted tasks that were resolved last week. For example, there was a bug with updating a user's edit-count after making a rollback edit, which is now fixed. [3]
Updates for technical contributors
Wikimedia REST API users, such as bot operators and tool maintainers, may be affected by ongoing upgrades. Starting the week of January 13, we will begin rerouting some page content endpoints from RESTbase to the newer MediaWiki REST API endpoints for all wiki projects. This change was previously available on testwiki and should not affect existing functionality, but active users of the impacted endpoints may raise issues directly to the MediaWiki Interfaces Team in Phabricator if they arise.- Toolforge tool maintainers can now share their feedback on Toolforge UI, an initiative to provide a web platform that allows creating and managing Toolforge tools through a graphic interface, in addition to existing command-line workflows. This project aims to streamline active maintainers’ tasks, as well as make registration and deployment processes more accessible for new tool creators. The initiative is still at a very early stage, and the Cloud Services team is in the process of collecting feedback from the Toolforge community to help shape the solution to their needs. Read more and share your thoughts about Toolforge UI.
- For tool and library developers who use the OAuth system: The identity endpoint used for OAuth 1 and OAuth 2 returned a JSON object with an integer in its
subfield, which was incorrect (the field must always be a string). This has been fixed; the fix will be deployed to Wikimedia wikis on the week of January 13. [4] - Many wikis currently use Cite CSS to render custom footnote markers in Parsoid output. Starting January 20 these rules will be disabled, but the developers ask you to not clean up your MediaWiki:Common.css until February 20 to avoid issues during the migration. Your wikis might experience some small changes to footnote markers in Visual Editor and when using experimental Parsoid read mode, but if there are changes these are expected to bring the rendering in line with the legacy parser output. [5]
Meetings and events
- The next meeting in the series of Wikimedia Foundation Community Conversations with the Wikimedia Commons community will take place on January 15 at 8:00 UTC and at 16:00 UTC. The topic of this call is defining the priorities in tool investment for Commons. Contributors from all wikis, especially users who are maintaining tools for Commons, are welcome to attend.
