Weekly highlight

• Last week, improvements to account security and two-factor authentication (2FA) features were enabled across all wikis. These changes include user interface improvements for Special:AccountSecurity, the support of multiple 2FA methods via authenticator apps and portable security keys (previously users could only enable one method), and a new Recovery Codes module which facilitates fewer account lockouts due to lost two-factor apps and devices. As part of the Account Security project, work is continuing through the rest of 2025 on further user experience improvements, and support for passkeys as an alternate second factor.

Updates for editors

• Another part of the Account security project is making 2FA generally available to all users. Along with editors with advanced privileges, such as administrators and bureaucrats, 40% of editors now have access to 2FA. You can check if you have access at Special:AccountSecurity. Instructions for activation are on the linked page. The plan is to continue increasing availability if it is determined that the user support capabilities are able to support global usage. [1]
• This week, users at wikis where talk page Usability Improvements are already available by default (everywhere except the 12 wikis listed in T379264) will gain the ability to Thank a comment directly from the talk page it appears on. Before this change, Thanking could only be done by visiting the revision history of the talk page. You can learn more about this change. [2]
• Users who have not verified their email address will soon be receiving monthly Notification reminders to do so. This is because users who have verified their email can more easily recover their account. These reminders will not be sent if the user is inactive or removes the unverified email from their account. [3][4]
• View all 21 community-submitted tasks that were resolved last week. For example, a fix was made for an occasional error with saving translated paragraphs in the Content Translation tool, and the related error messages are now easier to see. [5]

Updates for technical contributors

• The Unsupported Tools Working Group has chosen Video2Commons as the first tool for its pilot cycle. The group will explore ways to improve and sustain the tool over the coming months. Learn more on Meta.
• Detailed code updates later this week: MediaWiki

Updates for editors

• To optimize how user data is stored in our databases, the saved preferences of users who haven't logged in for over five years and have fewer than 100 edits will be cleared. When those users return, default settings will apply. [6]
• View all 20 community-submitted tasks that were resolved last week. For example, there was a broken link from the GlobalContributions interface message to the XTools GlobalContributions page which has now been fixed. [7]

Updates for technical contributors

• The work to reroute all traffic to API endpoints under the rest.php route through a common API gateway is now complete. If any issues are observed, please file a phabricator ticket to the Service Ops team board.
• Edits to Wikidata references or qualifiers will now be shown in RecentChanges and Watchlist entries on other wikis less often, reducing unnecessary notifications. This will reduce the overall quantity of 'noisy' entries. Wikidata's own pages remain unchanged. [8]

Updates for editors

• The Wikipedia iOS app has launched an A/B/C test of improvements made to the tabbed browsing feature for select regions and languages. The test, named “More dynamic tabs”, explores new tab experiences and includes “Did you know” and “Because you read” article recommendations. You can read more on the project page.
• Autoconfirmed users on small and medium wikis with the CampaignEvents extension can now use Event Registration without the Event Organizer right. This feature lets organizers enable registration, manage participants, and lets users register with one click instead of signing event pages.
• View all 31 community-submitted tasks that were resolved last week. For example, the issue of flashing colors when holding or pressing the arrow keys under the dark mode settings in Vector 2022 has been fixed. [9]

Updates for technical contributors

• The CampaignEvents extension will be deployed to all remaining wikis during the week of 17 November 2025. The extension currently includes three features: Event Registration, Collaboration List, and Invitation List. For this rollout, Invitation List will not be enabled on Wikifunctions and MediaWiki unless requested by those communities. Visit the deployment page to learn more.
• The SwaggerUI-based REST sandbox experience is now live on all wiki projects. The sandbox can be accessed through the Special:RestSandbox page. Please report any issues to the MediaWiki Interfaces team board, or join the discussion on the project launch page. [10]
• Transform endpoints with a trailing slash path in the MediaWiki REST API are now marked as deprecated. They will remain functional during this time, but removal is expected by the end of January 2026. All API users currently calling them are encouraged to transition to the non-trailing slash versions. Both endpoint variations can be found and tested using the REST Sandbox. See the MediaWiki REST API Deprecation page for more detailed information about the API deprecation policies and procedures.
• A dedicated changelog now exists for the MediaWiki REST API. The changelog provides an overview of these changes, making it easier for developers to keep track of improvements and iterations. Announcements will also continue to flow through the standard communication channels, including Tech News and email distribution lists, but can now be more easily referenced from a central location. If you have feedback about the style, structure, or content of this changelog, please join the discussion.
• Administrators can delete the tracking category which was previously added by the JsonConfig extension, as it is no longer used. See the categories linked from Q130635582. It is OK if there are still pages listed in the category as that is just a caching issue, and they will be automatically cleared out the next time each page is edited. [11]

Updates for editors

• Administrators will now find that Special:MergeHistory is now significantly more flexible about what it can merge. It can now merge sections taken from the middle of the history of the source (rather than only the start) and insert revisions anywhere in the history of the destination page (rather than only the start). [12]
• For users with "Automatically subscribe to topics" enabled in their preferences, starting a new topic or adding a reply to an existing topic will now subscribe them to replies to that topic. Previously, this would only happen if the DiscussionTools "Add topic" or "Reply" widgets were used. When DiscussionTools was originally launched existing accounts were not opted in to automatic topic subscriptions, so this change should primarily affect newer accounts and users who have deliberately changed their preferences since that time. [13]
• Scribunto modules can now be used to generate SVG images. This can be used to build charts, graphics and other visualizations dynamically through Lua, reducing the need to compose them externally and upload them as files. [14]
• Wikimedia sites now provide all anonymous users with the option to enable a dark mode color scheme, featuring light-colored text on a dark background. This enhancement aims to deliver a more enjoyable reading experience, especially in dimly lit environments. [15]
• Users with large watchlists have long faced timeouts when editing Special:EditWatchlist. The page now loads entries in smaller sections instead of all at once due to a paging update, allowing everyone to edit their watchlists smoothly. As part of the database update, sorting by expiry has been removed because it was over 100× slower than sorting by title. A community wish has been created to explore alternative ways to restore sort-by-expiry. If this feature is important to you, please support the wish! [16]
• View all 31 community-submitted tasks that were resolved last week. For example, the fixing of the persisting highlighting when using VisualEditor find and replace during a query. [17]

Updates for technical contributors

• Since 2019 the Wikimedia URL Shortener at https://w.wiki is available for all Wikimedia wikis to create short links to articles, permalinks, diffs, etc. It is available in the sidebar as "Get shortened URL". There are 30 wikis that also install an older "ShortUrl" extension. The old extension will soon be removed. This means /s/ URLs will not be advertised under article titles via HTML class="title-shortlink". The /s/ URLs will keep working. [18]
• On Thursday, October 30, the MediaWiki Interfaces and SRE Service Operations teams began rerouting Action API traffic through a common API gateway. Individual wikis will be updated based on the standard release groups, with total traffic increased over time. This change is expected to be non-breaking and non-disruptive. If any issues are observed, please file a Phabricator ticket to the Service Ops team board.
• MediaWiki Train deployments will pause for the final two weeks of 2025: 22 December and 29 December. Backport windows will also pause between Monday, 22 December 2025 and Thursday, 2 January 2026. A backport window is a scheduled time to add things like bug fixes and configuration changes. There are seven deployment trains remaining for 2025. [19]
• Detailed code updates later this week: MediaWiki

In depth

• In 2025, the Wikimedia Foundation reported that AI systems and search engines increasingly use Wikipedia content without driving users to the site, contributing to an 8% drop in human pageviews compared to 2024. After detecting bots disguised as humans, Wikimedia updated its traffic data to reflect this shift. Read more about current user trends on Wikipedia in a Diff blog post.

Updates for editors

• Starting November 12, users will see a change in the appearance of talk pages on some Wikipedias. Almost all wikis have received this design change; English Wikipedia will get these changes later. You can read more on Diff. Users can opt out of these changes in their user preferences in "Show discussion activity". [20]
• MediaWiki can now display a page indicator automatically while a page is protected. This feature is disabled by default. It can be enabled by community request. [21]
• Using the "Show preview" or "Show changes" buttons in the wikitext editor will now carry over certain URL parameters like 'useskin', 'uselang' and 'section'. This update also fixes an issue where, if the browser crashed while previewing an edit to a single section, saving this edit could overwrite the entire page with just that section’s content. [22][23][24]
• Wikivoyage wikis can use colored map markers in the article text. The text of these markers will now be shown in contrasting black or white color, instead of always being white. Local workarounds for the problem can be removed. [25]
• The Activity tab in the Wikipedia Android app is now available for all users. The new tab offers personalized insights into reading, editing, and donation activity, while simplifying navigation and making app use more engaging. [26]
• The Reader Growth team is launching an experiment called "Image browsing" to test how to make it easier for readers to browse and discover images on Wikipedia articles. This experiment, a mobile-only A/B test, will go live on English Wikipedia in the week of November 17 and will run for four weeks, affecting 0.05% of users on English wiki. The test launched on November 3 on Arabic, Chinese, French, Indonesian, and Vietnamese wikis, affecting up to 10% of users on those wikis. [27]
• View all 27 community-submitted tasks that were resolved last week. For example the inability to lock accounts on mobile sites has been fixed. [28]

Updates for technical contributors

• Nominations are open on Wikitech for new Toolforge standards committee members. The committee oversees the Toolforge Right to fork policy and Abandoned tool policy among other duties. Nominations will remain open through 2025-11-28.
• The JWT issuer field in OAuth 2 access tokens for SUL wikis has been changed to https://meta.wikimedia.org. Old access tokens will still work. [29]
• The JWT subject field in OAuth 2 access tokens will soon change from <user id> to mw:<identity type>:<user id>, where <identity type> is typically CentralAuth: (for SUL wikis) or local:<wiki id> (for other wikis). This is to avoid conflicts between different user ID types, and to make OAuth 2 access tokens and the sessionJwt cookie more similar. Old access tokens will still work. [30]
• MediaWiki's block messages (blockedtext, blockedtext-partial, autoblockedtext, systemblockedtext, blockedtext-tempuser, autoblockedtext-tempuser) now support additional parameters indicating whether the user is blocked from editing their own user talk page $9 or emailing other users $10. [31]
• A REL1_45 branch for MediaWiki core and each of the extensions and skins in Wikimedia git has been created. This is the first step in the release process for MediaWiki 1.45.0, scheduled for late November 2025. If you are working on a critical bug fix or working on a new feature, you may need to take note of this change. [32]
• The process for generating CirrusSearch dumps has been updated due to slowing performance. If you encounter any issues migrating to the replacement dumps, please contact the Search Platform Team for support. [33][34]

Updates for editors

• The Reader Experience team is experimenting with reading lists on mobile web, allowing logged-in readers with no edits to save private lists of articles for later. The experiment is running on Arabic, Chinese, French, Indonesian, and Vietnamese Wikipedias since the week of 10 November, and will begin on English Wikipedia the week of 17 November.
• Users who can’t receive their email verification code during login can now get help by submitting a form on a new special page. This update is part of the Account Security initiative. If your account has an email address, please make sure you still have access to it. When logging in from a new device or location without 2FA, you may be asked to enter a 6-digit code sent by email to finish logging in. Learn more.
• One new wiki has been created: a Wikisource in Minangkabau (s:min:) [35]
• View all 23 community-submitted tasks that were resolved last week.

Updates for technical contributors

• As part of the Parser Unification project, the Content Transform Team rolled out Parsoid as the default parser to many low-traffic Wikipedias and is preparing the next step to high traffic ones. This message is an invitation for you to opt-in to Parsoid, as described in the Extension:ParserMigration documentation, and identify any issues you might encounter with your own workflow using bots, gadgets, or user scripts. Please, let us know through the "Report Visual Bug" link in the Tools sidebar or create a phab ticket and tag the Content Transform Team in Phabricator.
• Unsupported Tools: Several issues with Video2Commons have been fixed, including filename-related upload failures, black-video imports, and retry handling. AV1 support has also been added. Ongoing work focuses on backend stability, ffmpeg errors, subtitle imports, metadata handling, and playlist uploads. To track specific tasks, check the Phabricator board.
• Detailed code updates later this week: MediaWiki

Updates for editors

• Last week, the Wikimedia Search Team recreated the "DWIM" (Do What I Mean) gadget functionality server-side, for Russian and Hebrew Wikipedias. This feature adds cross-keyboard suggestions to the standard search-box suggestions. For example, searching for cxfcnmt on Russian Wikipedia will now add suggestions for счастье ("happiness") that the user probably intended. They plan to enable this feature for other Russian and Hebrew wikis this week. [37]
• Later this week, users of the "Improved Syntax Highlighting" beta feature will have syntax highlighting available in DiscussionTools. This requires that the "Enable editing tools in source mode" preference be set. [38]
• Campaign events extension – the set of tools for coordinating events and other on-wiki collaborations has now been deployed to all Wikimedia wikis. A new feature known as Collaborative contribution to help organizers and participants see the impact of activities has also been added. Join the upcoming learning session to see the new feature in action and share your feedback.
• View all 24 community-submitted tasks that were resolved last week. For example, the bug which stopped CodeReviewBot from working, has now been fixed. [39]

Updates for technical contributors

• Users of Wikimedia API can join a usability study to help validate the new design of Wikimedia REST API sandboxes. Interested participants should fill the recruitment survey. [40]
• The MediaWiki Interfaces team is deprecating XSLT stylesheets within the Action API. Support for format=xml&xlst={stylesheet} will be removed from Wikimedia projects by the end of November, 2025. In addition, it will soon be disabled by default in MediaWiki release versions: v1.43 (LTS), v1.44, and v1.45. Support for XSLT stylesheets will be fully removed from MediaWiki v1.46 (expected to release between April and May 2026). [41]
• The WDQS legacy endpoint (query-legacy-full.wikidata.org) will be decommissioned at the end of December 2025, and finally closed down on 7th January 2026. After this date, users should expect requests to query.wikidata.org that require the full graph to fail or return invalid results if they are not rewritten to use SPARQL federation. The team encourages users to ensure that tools and workflows use the supported WDQS endpoints (https://query.wikidata.org/ - Main graph or https://query-scholarly.wikidata.org/ - Scholarly graph). For support with migrating use cases, please review the Data Access and Request a Query pages for details and assistance on alternative access methods.

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. [42]
• Two new wikis have been created:
  • a Wikipedia in Toki Pona (w:tok:) [43]
  • a Wikiquote in Nigerian Pidgin (q:pcm:) [44]

Updates for technical contributors

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. [45]
• 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. [46]
• 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. [47]

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. [48]
• 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. [49]
• 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. [50]

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. [51]

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. [52]
• 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. [53]

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. [54]
• 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.
