Updates for editors

• The Wikipedia Year in Review 2025 will be available on December 2 for users of iOS and Android Wikipedia apps, featuring new personalized insights, updated reading highlights, and refreshed designs. Learn more on the review's project page.
• The Growth team is working on improving the text and presentation of the Verification Email sent to new users to make them more welcoming, useful and informative. Some new text have been drafted for A/B testing and you can help by translating them. See Phabricator.
• Add a link will now be deployed at Japanese, Urdu and Chinese Wikipedias on December 2. Add a link is based on a prediction model that suggests links to be added to articles. While this feature has already been available on most Wikipedias, the prediction model could not support certain languages. A new model has now been developed to handle these languages, and it will be gradually rolled out to other Wikipedias over time. If you would like to know more, please contact Trizek (WMF).
• View all 34 community-submitted tasks that were resolved last week. For example, the issue where search boxes on some Commons pages showed no results due to switch from SpecialSearch to MediaSearch, has now been fixed. [1]
• Two new wikis have been created:
  • a Wikipedia in Toki Pona (w:tok:) [2]
  • a Wikiquote in Nigerian Pidgin (q:pcm:) [3]

Updates for technical contributors

• Detailed code updates later this week: MediaWiki

In depth

• The Wikimedia Foundation is in the early stages of exploring approaches to Article guidance. The initiative aims to identify interventions that could help new editors easily understand and apply existing Wikipedia practices and policies when creating an article. The project is in the exploration and early experimental design phase. All community members are encouraged to learn more about the project, and share their thoughts on the talk page.

Weekly highlight

• Anybody who wishes to secure their user account can now use two-factor authentication (2FA). This is available to all registered users of all Wikimedia projects. This is part of the Account Security initiative. Later, 2FA will be required for all users who can take security- or privacy-sensitive actions.

Updates for editors

• Following last week's deployments, the Add a link feature, which allows editors to add suggested links during editing, will be available to an additional 33 Wikipedias starting on 9 December. This expansion is possible thanks to the new prediction model that now supports all languages, including those that were previously not covered. While the feature has been available on most Wikipedias for some time, this rollout brings us closer to using the improved model everywhere. If you have any questions or would like more details please contact Trizek (WMF).
• Last week, the Search Platform team added transliterated as-you-type search suggestions to Georgian wikis. If there are only a few regular search suggestions, then queries in Latin or Cyrillic script are now rewritten into Georgian script to look for more matches. For example, searching for either bedniereba or бедниереба will now suggest the existing article about ბედნიერება ("happiness"). You can recommend other languages where transliterated suggestions would be useful on Phabricator for future development.
• Later this week, a controlled experiment will begin for editors on the 100 largest Wikipedias who are editing a section in the mobile web visual editor. 50% of these editors will notice a new "Edit full page" button that will enable them to expand their editing session to the whole page. This feature is intended to make it easier for people on mobile web to edit any article section, regardless of which section-edit icon they tapped to begin. The experiment will last ~4 weeks. You can find more details about the project.
• Later this week, the Reader Growth team will launch a mobile web experiment to expand all article sections by default (currently they are collapsed by default) and pin the section header the user is currently reading to the top of the page. The experiment will affect 10% of users on Arabic, Chinese, French, Indonesian, and Vietnamese Wikipedias. [4]
• The Wikipedia Year in Review 2025, a feature in the Wikipedia mobile apps (iOS and Android) that provides users with a personalised summary of their engagement with Wikipedia over the year, is now available on the iOS and Android apps. This edition includes expanded personalised insights, improved reading highlights, new donor messaging, and updated designs. Open the app to view your Year in Review and explore your reading journey from 2025.
• A recent software bug caused edits made with VisualEditor to make unintended changes to wikitext, including removing whitespace and replacing spaces with underscores in wikilinks inside citations. This was partially fixed last week, and further fixes are in progress. Editors who used VisualEditor between November 28 and December 2 should review their edits for unexpected modifications. [5]
• View all 23 community-submitted tasks that were resolved last week. For example, the incorrect handling of URLs copied from the address bar of Microsoft Edge users, has been resolved. [6]

Updates for technical contributors

• Starting this week, users of the "Improved Syntax Highlighting" beta feature will have CodeMirror as the editor for Lua, JavaScript, CSS, JSON and Vue content models, instead of CodeEditor. With this, the linters will be upgraded. This is part of a larger effort to eventually replace CodeEditor and provide a consistent code editing experience. [7]
• Developers are encouraged to take the 2025 Developer Satisfaction Survey, which remains open until 5 January 2026. If you build software for the Wikimedia ecosystem and would like to share your experiences or feedback, your participation is greatly appreciated. [8]
• There is no new MediaWiki version this week.

Updates for editors

• View all 18 community-submitted tasks that were resolved last week. For example, one of the fixes addressed an issue for temporary accounts adding an external URL, which triggered an hCaptcha request in more cases than intended, and did not display the required popup on the first attempt to publish the edit. [9]

Updates for technical contributors

• To improve database and site performance, external links to Wikimedia projects will no longer be stored in the database. This means they will not be searchable in Special:LinkSearch, will not be checked by the Spam Blacklist or AbuseFilter as new links, and will not be in the externallinks table on database replicas. In the future this may be extended to other highly-linked trusted websites on a per-wiki basis, such as Creative Commons links on Wikimedia Commons. [10]

Updates for editors

• From January, edit filters can be set to automatically suppress their details such as rules and list of attempted edits and actions. This will help oversighters use edit filters to prevent doxxing or other suppressible material. [11]
• The next issue of Tech News will be sent out on 12 January 2026 because of the end of year holidays. Thank you to all of the translators, and people who submitted content or feedback, this year.
• View all 16 community-submitted tasks that were resolved last week. For example, the crash that occurred when tapping "First Steps" in the Wikipedia Android Year in Review has now been fixed, and the feature opens as expected. [12]

Updates for technical contributors

• Interface elements such as diffs and categories generated by MediaWiki used to have the attribute data-mw="interface" to distinguish from wiki content. The attribute has been replaced with data-mw-interface="", to avoid potential conflicts with other data-mw attributes, which are generated by Parsoid. [13]
• There is no new MediaWiki version this week or next week.

Meetings and events

• The Wikimedia Hackathon Northwestern Europe 2026 will take place on 13-14 March 2026 in Arnhem, the Netherlands. Applications just opened mid-December and will close in mid-January or earlier if capacity is reached. With space for approximately 100 participants, early application is encouraged.
