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. [1]

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. [2][3]
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.

Updates for technical contributors

The legacy CSS classes tleft and tright have been replaced with floatleft and floatright as 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 that floatleft and floatright may 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. [5]

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. [6]

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. [7]
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. [8]

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'); use mw.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 of addPortletLink() 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. [9]
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.

Weekly highlight

The Reader Growth team has launched an Image Browsing beta feature on the mobile web version of all Wikipedias. The feature shows an image carousel at the top of articles with 3 or more images. Editors can configure this feature with the following controls: to hide a specific image from a page, either use class=notpageimage excluding it from thumbnail previews, or class=noviewer excluding it from MediaViewer. The carousel can also be disabled from a page entirely, with the magic word __NOMEDIAVIEWERCAROUSEL__. To submit feedback or flag bugs, please visit the project page.
Wikitables can now be sorted in descending order on the first click by adding data-sort-order="desc" to the header cell. Previously, by default, clicking a column header for the first time sorts it in ascending order. This addition to a Wikitable gives it more control and flexibility, while the default behavior for subsequent clicks remains unchanged. [10]

Updates for editors

The Article guidance feature is currently being tested with some editors creating new articles on the Simple English, French, and Turkish Wikipedias. The experiment will soon begin on the Arabic and Bangla Wikipedias as well. This feature gives editors community-curated guidance to help them create articles that follow community standards. Experienced editors can continue creating or adapting outlines for specific article types that are commonly created by less experienced contributors. The outlines guide less experienced editors in creating high-quality articles. A quick guide to markups used in outlines can be found on this page. Example outlines that can be adapted and instructions for how to adapt them are on this section of the project page.
Wikis that wish to replace the "indefinitely" button in Special:Block for temporary accounts (for example, wikis that block temporary users only until account expiration) will be able to do so by creating MediaWiki:ipb-indefinite-expiry-temporary-account with the block duration they want. [11]

Updates for technical contributors

By the end of June, a valid user-agent string will be required for automated dumps downloads from the dumps.wikimedia.org website. Automated requests that provide a generic or empty user-agent will be blocked. This extends enforcement of the long standing user-agent policy. Access to dumps through Wikimedia Cloud Services will not change.
The roll out of global API rate limits is now complete, with limits enforced across all APIs and at the documented levels for all groups. Bots running in Toolforge/WMCS or with the bot user right on any wiki remain exempt. All bots should continue to follow the documented best practices to avoid being rate limited.
The API Portal wiki will be read only starting this week (June 15-18). The following week (June 22-25), all API Portal wiki URLs will redirect to Wikimedia APIs on mediawiki.org. Learn more on the project page.

Starting next week, abuse filters that are set to "require CAPTCHA verification" will begin to also affect users with the skipcaptcha right, which includes most autoconfirmed users. Bots are exempted. This change only affects edits that trigger an abuse filter. The skipcaptcha right will continue to exempt users from having to solve CAPTCHAs in the ordinary course of using the wikis. [15]
Reference documentation for the Lift Wing API has moved from the API Portal to the interactive REST Sandbox.
The API Portal wiki is now closed. For API documentation, see Wikimedia APIs on mediawiki.org. All API Portal wiki URLs (https://api.wikimedia.org/wiki/) will redirect to the mediawiki.org page starting June 22. [16]
