Tech News: 2026-19
[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 Article guidance team invites experienced editors of pilot Wikipedias—Arabic, Bangla, Japanese, Portuguese, Persian, Turkish, Simple English, Spanish, and French—to help translate and adapt sample outlines. These outlines will guide editors in creating clear, well-structured, and policy-compliant articles when using the feature once it is launched in May 2026. Simple instructions on how to translate and adapt the outlines are available.
Updates for editors
- The Product and Technology Advisory Council has published draft recommendations on a model that affiliates can follow when contributing to the technical space. Community members are invited to provide feedback on the recommendation until May 8th on the talk page.
- The number of available thumbnail size preferences in MediaWiki is being reduced to three standardized options—Small (180px), Regular (250px), and Large (400px), as part of ongoing efforts to improve performance and reduce strain on thumbnail services. As a result, existing preferences will be mapped to the nearest new size (for example, smaller selections like 120px or 150px will render at 180px, while larger ones like 300px or 360px will render at 400px). The preferences interface will soon be updated to reflect these changes, and users who wish to opt out or provide feedback can do so. [1]
- From now on, even when a permission expires automatically, users will receive an Echo notification similar to the standard notification for permission changes. There is a difference between this and Global reminder bot in that the latter reminds users a week before the rights are due to expire, so that they can renew the rights.
View all 32 community-submitted tasks that were resolved last week. For example, the problem where the ULS language selector in Special:Translate would scroll vertically when it shouldn't, has been resolved. Previously, when users opened the "Translate to English" dropdown and typed certain inputs, the dialog would scroll vertically by a few pixels even when there was enough space to display all results. The dropdown no longer shifts unnecessarily when filtering languages. [2]- The Global Watchlist, which lets you view your watchlists from multiple wikis on a single page, continues to improve. For example, watchlists for Wikibase sites such as Wikidata now support EntitySchema elements for better tracking. The Live Updates mode now refreshes the special page every 60 seconds to comply with the updated global API rate limits for improved real-time responsiveness. Additionally, a directionality bug that displayed links as "changes 3" instead of "3 changes" in mixed-direction lists has been fixed. [3][4][5]
Updates for technical contributors
- The second phase of global API rate limits has been rolled out to reduce the impact of AI crawlers and ensure fair, sustainable access to Wikimedia resources, prioritising human and mission-aligned traffic. Limits have been shifted from per-hour to per-minute, producing smoother traffic patterns and more predictable API load. Community users are not expected to be affected, and no action is required. Early indications show some User-Agent-based requestors are adjusting behaviour, and around 64% of automated API traffic has been identified. Monitoring continues, and Wikimedia Enterprise remains available for commercial support.

[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. [6]
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. [7]- Detailed code updates later this week: MediaWiki

[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. [8]
- 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. [9]
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.

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.

[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. [10]
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. [11][12]
- 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. [13]
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. - Detailed code updates later this week: MediaWiki
