[edit]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
- Community Tech has published new guidance explaining how wishes on Community Wishlist are triaged and prioritized. The documentation is intended to help contributors write stronger proposals by clarifying the factors that influence prioritization decisions. Beyond vote counts, the guidance highlights considerations such as potential impact on the community when determining which wishes move forward.
Updates for editors
- The Reader Growth team is launching an experiment to test a new Share Card feature that allows readers to create visually engaging cards from Wikipedia articles or selected article sections and share them online, with each card linking back to the original article to help expand readership and article discovery. The mobile-only A/B test will be available to a portion of readers on Arabic, Chinese, French, Vietnamese, and English Wikipedia to better understand reading and sharing habits, and is scheduled to begin the week of May 18 and run for four weeks.
- The Android and iOS Wikipedia apps recently released the 25-day reading challenge into Beta, as part of efforts to drive reader engagement by encouraging users to complete reading milestones. To track their reading streak during the challenge, App users can add a widget featuring Baby Globe to their home screen. The challenge officially begins May 11.
View all 17 community-submitted tasks that were resolved last week. For example, an issue where the global preference for enabling syntax highlighting in wikitext could unexpectedly disable itself after being turned on, has now been fixed. [1]
Updates for technical contributors
The ResourceLoader module mediawiki.ui.input, deprecated since September 2023, will be removed this week. There is a guide for migrating from MediaWiki UI to Codex for any tools that use it. [2]

Tech News: 2026-21
[edit]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 Abstract Wikipedia team has identified five potential pilot wikis to assess their interest in adopting abstract articles on their wikis. The pilots are Malayalam, Bengali, Dagbani, Arabic, and Indonesian Wikipedia. The feedback period will be open until May 22. If your community is interested in becoming a pilot, let us know on Meta.
Updates for editors
- An experiment to show Reading Lists to logged-out readers on mobile web will launch on May 18 across German, Spanish, Italian, Portuguese, Polish, Dutch, Turkish, and Urdu Wikipedias, and will run for one month. The effort supports broader goals of helping readers save and organize articles for later reading, while encouraging habits that could lead to future Wikipedia contributions.
- To support a bookmark button in the Reading List beta feature, the "Tools > Action" menu has been updated to display icons, including the watch star indicator that helps editors identify temporarily watched articles. The icons now also match those used on mobile, improving consistency across platforms. The change is currently limited to the actions menu and mainly affects editors with privileged user rights. [3]
- Suggestion Mode was released as an A/B test for newcomer editors on the mobile website at ~15 Wikipedias. The experiment will measure the impact that Suggestion Mode has on the proportion of newcomer mobile web edit sessions that result in constructive (un-reverted) article edits. The experiment will also evaluate the feature's impact on editor retention, and monitor changes in revert and block rates.
View all 27 community-submitted tasks that were resolved last week. For example, an issue in the Wikipedia Android app where images could sometimes fail to load after opening a recommended reading list notification, has now been fixed. [4]
Updates for technical contributors
- The Wikidata Platform team has published its backend replacement recommendation and accompanying technical architecture for the migration of the Wikidata Query Service (WDQS) away from Blazegraph. Feedback is invited until May 25th 2026, especially on potential gaps and impacts on advanced use cases. Wikidata community members and WDQS users are also encouraged to help identify high-impact tools and workflows that may need attention on this page. Feedback can be shared on the Migration talk page or during the next office hour. See the WDP team newsletter for more details.
Detailed code updates later this week: MediaWiki
In depth
- On English, French, Japanese, and a few other Wikipedias, there was a trial of hCaptcha, a third-party bot detection service. The trial showed that hCaptcha effectively detects and deters some bad-faith automated activity, on its own and by giving checkusers and stewards signals to look into. Because the results were positive, hCaptcha will be rolled out across all wikis over the next few weeks. See the hCaptcha project page for technical information about the implementation and privacy protections. Learn more.
- The latest Community Tech update is now available, with progress across several Community Wishlist initiatives, including Reading Lists expansion from the mobile app to the website, new language support for "Who Wrote That" and the Personal Dashboard, improvements to 3D rendering and Charts, and upcoming work on talk page sorting, audio playback, and editing workflows. The update also shares current priorities, wishlist status trends, and opportunities for community feedback on future focus areas and the Wikimedia Foundation’s 2026–2027 Annual Plan. Read the full newsletter for details.

Tech News: 2026-22
[edit]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
- Following a successful account creation experiment, an improved logged-out edit warning message will be deployed to all Wikimedia wikis in the first week of June. The change will only affect logged-out users on mobile web who open an editing session. The updated experience is designed to encourage account creation more clearly, while still allowing users to edit with temporary accounts. Results from the experiment showed a significant increase in account creation, with a 27% relative lift among users shown the updated message. As expected, as more people funnel into account creation, temporary accounts decreased by a relative 16%. The experiment did not show any significant changes in constructive edit rates or other monitored contributor metrics. [5]
Updates for editors
- For security reasons, members of certain user groups are required to have two-factor authentication (2FA) enabled. Members of these groups will be unable to disable the last 2FA method on their account, and it will be impossible to add users without 2FA to these groups. Users will still be able to add new authentication methods or remove them, as long as at least one method is continuously enabled. In the next few weeks, users without 2FA will be removed from these groups. Notably, this applies to bureaucrats. See the linked tasks for deployment schedules. [6][7]
- WMDE Technical Wishes will run an A/B test on 10 wikis, testing potential improvements for Reference Previews. The experiment will run for ~2 weeks at the end of May / beginning of June and will affect 10% of desktop readers on the participating wikis.
- After two successful experiments, the Reader Growth team is rolling out an Image Browsing beta feature for all Wikipedias on mobile on May 25. This means that anyone who has all beta features on by default will start to see this feature, and others can check the box to turn it on in their preferences. The beta feature will include a carousel of all an article's images at the top of the article, with controls for editors to exclude images from the article's carousel or to exclude an article from the feature entirely.
View all 30 community-submitted tasks that were resolved last week. For example, three dimensional STL files were being rendered incorrectly by the media viewer 3D extension which is now fixed. [8]
Updates for technical contributors
- The legacy CSS classes
tleftandtrighthave been replaced withfloatleftandfloatrightas the former do not work consistently across all MediaWiki platforms, notably mobile web and mobile apps. Projects relying on these classes are encouraged to review related usage and plan for migration. Please note thatfloatleftandfloatrightmay also be deprecated in future, although there are currently no plans to do so. Read more.

Updates for editors
- The Reader Experience team is conducting an experiment to show the reading lists feature, which is still in development, to logged-out mobile readers to test whether it encourages account creation at a higher rate compared to the watchstar button. The experiment was launched on May 18th on German, Spanish, Italian, Portuguese, Polish, Dutch, Turkish, and Urdu wikis, and it will run for a month.
- The Wikimedia Apps team released Phase 1 of the redesigned Home Feed to the Android Beta app. The new Home Feed includes a refreshed "Community" tab and a personalized "For You" tab featuring daily updated reading recommendations. The redesign is part of a broader effort to improve content discovery and create more engaging learning experiences in the Wikipedia apps.
View all 18 community-submitted tasks that were resolved last week. For example, an issue where images could fail to load for some suggested edits on Special:Homepage, leaving the thumbnail stuck in a loading state, has now been fixed. [9]

Tech News: 2026-24
[edit]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
- Wikimedia Enterprise has increased the free usage limits for its API offerings. The monthly request limit for the On-demand API has increased from 5,000 to 50,000 requests, while the Snapshot API limit has increased from 15 to 30 requests per month. In addition, Structured Contents snapshots are now available for free accounts. These changes expand access to Wikimedia Enterprise data for developers, researchers, and organizations using Wikimedia content. [10]
Updates for editors
- The refreshed Explore Feed, now called the Home Feed, is rolling out to 50% of users of the Wikipedia Android app. The Home Feed helps readers discover relevant content through two new tabs: Community and For You. The Community tab provides a scrollable feed of curated content and updates from the broader Wikimedia community and movement, while the For You tab offers a full-screen, swipeable experience that shows content tailored to a user's interests. The redesign is part of a broader effort to improve discovery and enhance the learning experience in the Wikipedia app.
- The Which came first? daily trivia game is now available in the beta version of the Wikipedia iOS app in English, German, French, Portuguese, Russian, Spanish, Arabic, Chinese, and Turkish. The game uses historical events from Wikipedia's "On This Day" content and challenges readers to guess which of two events happened first. The game was previously released on Android. Communities interested in making the game available in their languages can read the instructions and requirements.
- Sub-referencing, a new MediaWiki feature that allows editors to reuse references with different details, will begin rolling out to Wikimedia wikis following a successful pilot phase. Deployment will start on 8 June for most Group 1 wikis and French Wikipedia, with additional Wikipedia language editions receiving the feature over the coming months. Communities are encouraged to prepare by checking for untranslated Cite extension messages in their language and reviewing any use of Reference Tooltips, which may require updates to support the new functionality. Wikis using Reference Previews do not need to take any action. Communities may also wish to create the cite-tracking-category-ref-details tracking category as a hidden category using
__HIDDENCAT__(or a dedicated template), and connect it to the corresponding Wikidata item d:Q129764848. [11] - The Page Previews experiment on mobile web has concluded. The team decided not to roll out the feature after the results showed no statistically significant impact on reader retention, as the primary success metric was retention improvement. Page Previews, which are already available on desktop and in the apps, display a thumbnail, lead paragraph, and link to the full article when readers tap a blue link. The experiment tested this experience on mobile web across six Wikipedias.
- The user interface icon library will be updated later this week or next week. Most of the ~300 icons have been slightly refined and ~30 new icons have been added. These changes improve the icons to make them more consistent and comprehensible, and provide more visual balance when they are used in groups.
- The Universal Language Selector (ULS) interface in MediaWiki, which helps users select content in other languages, has been updated. The new version improves speed and accessibility, and users of Wikimedia projects can now pin languages for quicker language switching. The deployment to Wikimedia sites will happen gradually in the coming weeks. You can test it now as a beta feature by selecting beta features in your profile preferences and share your feedback on the project page.
View all 21 community-submitted tasks that were resolved last week. For example, an issue where the Pageviews Analysis dashboard on pageviews.wmcloud.org stopped updating graph data in May 2026, affecting all users, has been fixed. [12]
Updates for technical contributors
- The function signature for
mw.util.addPortletLink()has been simplified. Developers can now pass a configuration object instead of a list of positional parameters when creating portlet links. The previous function signature remains supported for backwards compatibility. For example, instead of:mw.util.addPortletLink('p-cactions', '#', 'Stub', 'ca-stubtag', 'Add a stub tag to this page');usemw.util.addPortletLink('p-cactions', { href: '#', text: 'Stub', id: 'ca-stubtag', tooltip: 'Add a stub tag to this page' });. Script maintainers are encouraged to review existing uses ofaddPortletLink()and update them where appropriate. This change will be available on all wikis from 11 June. Thanks to community volunteer Gerges for contributing this improvement. [13] - Community Wishlist discussion: Product & Technology introduced changes meant to increase the number and complexity of wishes fulfilled, including the disbanding of the Community Tech team. They are engaging in discussions about a proposed direction for the wishlist from community members. Includes ways to structure annual voting, better tracking of wishes, removing focus areas, and staffing updates.
