Weekly highlight

• All wikis will be read-only for a few minutes on Wednesday, 25 March 2026 at 15:00 UTC. This is for the datacenter server switchover backup tests, which happen twice a year. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.
• Last week, all wikis had 2 hours of read-only time, and extended unavailability for user-scripts and gadgets. This was due to a security incident which has since been resolved. Work is ongoing to prevent re-occurrences. For current information please see the post on the Stewards' noticeboard (translations).

Updates for editors

• Users facing multiple blocks on mobile will now see the reasons for each block separately, instead of a generic message. This helps them understand why they are blocked and what steps they can take to resolve the issue. For example, users affected for using common VPNs (such as iCloud Private Relay) will receive clearer guidance on what they need to do to start editing again.
• Later this week, Suggestion Mode will become available as a beta feature within the visual editor at all Wikipedias. This feature proactively suggests various types of actions that people can consider taking to improve Wikipedia articles, and learn about related guidelines. The feature is locally configurable, and can also be locally expanded with custom Suggestions. Current settings can be seen at Special:EditChecks and there are instructions for how administrators can customize the links to point to local guidelines. The feature is connected to Edit check which suggests improvements while someone is writing new content. In the future, the Editing team plans to evaluate the feature's impact with newcomers through a controlled experiment.
• View all 23 community-submitted tasks that were resolved last week. For example, the issue where the cursor became misaligned during the use of CodeMirror’s syntax highlighting, which makes wikitext and code easier to read, has now been fixed. This problem specifically affected users who defined a font rule in a custom stylesheet while creating a new topic with DiscussionTools.

Updates for technical contributors

• API rate limiting update: To help ensure fair use of infrastructure, global API rate limits will be applied this week to requests without a compliant User-Agent that originate from outside Toolforge/WMCS and to unauthenticated requests made from web browsers. Higher limits will be applied to identified traffic in April. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see Wikimedia APIs/Rate limits.
• The new GraphQL API has been released. The API was developed as a flexible alternative to select features of the Wikidata Query Service (WDQS), to improve developer experience and foster adaptability, and efficient data access. Try it out and give feedback. You can also sign up for usability tests.
• The PTAC Unsupported Tools Working Group continued improvements to Video2Commons in February, with fixes addressing authentication errors, large-file handling, task queue visibility, and clearer upload behavior. Work is still ongoing in some areas, including changes related to deprecated server-side uploads. Read this update to learn more.
• Detailed code updates later this week: MediaWiki

• The Article Guidance team invites experienced Wikipedia editors from selected pilot wikis and interested contributors from other Wikipedias to fill out this questionnaire which is available in English, Arabic, Bengali, Japanese, Portuguese, Persian, and Turkish. Your answers will help the team customize guidance for less experienced editors and help them learn community policies and practices while creating an article. Learn more on the project page.

Updates for editors

• The Improved Syntax Highlighting beta feature, also known as CodeMirror 6, has been used for wikitext syntax highlighting since November 2024. It will be promoted out of beta by May 2026 in order to bring improvements and new features to all editors who use the standard syntax highlighter. If you have any questions or concerns about promoting the feature out of beta, please share.
• Some changes to local user groups are performed by stewards on Meta-Wiki and logged there only. Now, interwiki rights changes will be logged both on Meta-Wiki and the wiki of the target user to make it easier to access a full record of user's rights changes on a local wiki. Past log entries for such changes will be backfilled in the coming weeks.
• On wikis using Flagged Revisions, the number of pending changes shown on Special:PendingChanges previously counted pages which were no longer pending review, because they have been removed from the system without being reviewed, e.g. due to being deleted, moved to a different namespace, or due to wiki configuration changes. The count will be correct now. On some wikis the number shown will be much smaller than before. There should be no change to the list of pages itself.
• Wikifunctions composition language has been rewritten, resulting in a new version of the language. This change aims to increase service stability by reducing the orchestrator's memory consumption. This rewrite also enables substantial latency reduction, code simplification, and better abstractions, which will open the door to later feature additions. Read more about the changes.
• Users can now sort search results alphabetically by page title. The update gives an additional option to finding pages more easily and quickly. Previously, results could be sorted by Edit date, Creation date, or Relevance. To use the new option, open 'Advanced Search' on the search results page and select 'Alphabetically' under 'Sorting Order'.
• View all 28 community-submitted tasks that were resolved last week. For example, the bug that prevented UploadWizard on Wikimedia Commons from importing files from Flickr has now been fixed.

Updates for technical contributors

• A new special page, Special:LintTemplateErrors, has been created to list transcluded pages that are flagged as containing lint errors to help users discover them easily. The list is sorted by the number of transclusions with errors. For example: Special:LintTemplateErrors/night-mode-unaware-background-color.
• Users of the Improved Syntax Highlighting beta feature have been using CodeMirror instead of CodeEditor for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages, for some time now. Along with promoting CodeMirror 6 out of beta, the plan is to replace CodeEditor as the standard editor for these content models by May 2026. Feedback or concerns are welcome.
• The CodeMirror JavaScript modules will soon be upgraded to CodeMirror 6. Leading up to the upgrade, loading the ext.CodeMirror or ext.CodeMirror.lib modules from gadgets and user scripts was deprecated in July 2025. The use of the ext.CodeMirror.switch hook was also deprecated in March 2025. Contributors can now make their scripts or gadgets compatible with CodeMirror 6. See the migration guide for more information.
• The MediaWiki Interfaces team is expanding coverage of REST API module definitions to include extension APIs. REST API modules are groups of related endpoints that can be independently managed and versioned. Modules now exist for GrowthExperiments and Wikifunctions APIs. As we migrate extension APIs to this structure, documentation will move out of the main MediaWiki OpenAPI spec and REST Sandbox view, and will instead be accessible via module-specific options in the dropdown on the REST Sandbox (i.e., Special:RestSandbox, available on all wiki projects).
• The Scribunto extension provides different pieces of information about the wiki where the module is being used via the mw.site library. Starting last week, the library also provides a way of accessing the wiki ID that can be used to facilitate cross-wiki module maintenance.
• Detailed code updates later this week: MediaWiki

Weekly highlight

• Wikimedia site users can now log in without a password using passkeys. This is a secure method supported by fingerprint, facial recognition, or PIN. With this change, all users who opt for passwordless login will find it easier, faster, and more secure to log in to their accounts using any device. The new passkey login option currently appears as an autofill suggestion in the username field. An additional "Log in with passkey" button will soon be available for users who have already registered a passkey. This update will improve security and user experience. The screen recording demonstrates the passwordless login process step by step.
• All wikis will be read-only for a few minutes on Wednesday, 25 March 2026 at 15:00 UTC. This is for the datacenter server switchover backup tests, which happen twice a year. During the switchover, all Wikimedia website traffic is shifted from one primary data center to the backup data center to test availability and prevent service disruption even in emergencies.

Updates for editors

• Wikimedia site users can now export their notifications older than 5 years using a new Toolforge tool. This will ensure that users retain their important notifications and avoid them being lost based on the planned change to delete notifications older than 5 years, as previously announced.
• Wikipedia editors in Indonesian, Thai, Turkish, and Simple English now have access to Special:PersonalDashboard. This is an early version of an experience that introduces newer editors to patrolling workflows, making it easier for them to move from making edits to participating in more advanced moderation work on their project.
• The Special:Block now has two minor interface changes. Administrators can now easily perform indefinite blocks through a dedicated radio button in the expiry section. Also, choosing an indefinite expiry provides a different set of common reasons to select from, which can be changed at: MediaWiki:Ipbreason-indef-dropdown.
• Mobile editors at several wikis can now see an improved logged-out edit warning, thanks to the recent updates from the Growth team. These changes released last week are part of ongoing efforts and tests to enhance account creation experience on mobile and then increase participation.
• View all 36 community-submitted tasks that were resolved last week. For example, the bug that prevented mobile web users from seeing the block information when affected by multiple blocks has been fixed. They can now see messages of all the blocks currently affecting them when they access Wikipedia.

Updates for technical contributors

• Images built using Toolforge will soon get the upgraded buildpacks version, bringing support for newer language versions and other upstream improvements and fixes. If you use Toolforge Build Service, review the recent cloud-announce email and update your build configuration as necessary to ensure your tools are compatible.

• The API Portal documentation wiki will shut down in June 2026. API keys created on the API Portal will continue to work normally. api.wikimedia.org endpoints will be deprecated gradually starting in July 2026. Documentation on the API Portal is moving to mediawiki.org. Learn more on the project page.
• Detailed code updates later this week: MediaWiki

Weekly highlight

• The Beta version of Abstract Wikipedia a new Wikimedia project which is language-independent, was launched last week. The project allows communities to build Wikipedia articles in their native language, which can be readily accessed by other users in their own languages. The wiki is powered by instructions from Wikifunctions and also based on structured content from Wikidata. Read more.

Updates for editors

• The Growth team is running an A/B test to evaluate a clearer, more user-friendly message that promotes account creation on wikis. Currently when logged-out mobile users begin editing, they see a jarring warning message that can feel abrupt and discouraging. This also presents temporary account editing as the default rather than encouraging account creation. The test is running on ten Wikipedias, including Arabic, French, Spanish and German. Read more.
• The Wikimedia Apps team is inviting feedback on how editing should work on the Wikipedia mobile apps. The discussion focuses on improving how users access editing tools when they tap "Edit". This is part of a broader effort to convert readers who develop an interest in editing, to access a more user-friendly pathway to start contributing.
• View all 45 community-submitted tasks that were resolved last week. For example, an issue where citation fetching from the large newspaper archive Newspapers.com was no longer working, due to a block in Citoid requests, has now been fixed.

Updates for editors

• The CampaignEvents extension now includes a new group goal-setting feature, enabling organizers to set and track event goals such as the number of articles created and participating contributors in real time. Similarly, participants can work toward shared targets and see their collective impact as the event unfolds. The feature is now available on all Wikimedia wikis. Learn more in the documentation.
• The new watchlist labels feature (announced in Tech News 2026-07) is now available via VisualEditor, the source editor, and the 'watchstar' (or watch link, for skins that don't have a star icon). Previously it was only possible to assign labels via EditWatchlist. In all three places it is a new field following the expiry field.
• View all 23 community-submitted tasks that were resolved last week. For example, the issue where talk pages on mobile with Parsoid are unusable after empty section headers, has now been fixed.

Updates for technical contributors

• The sub-referencing feature, which lets editors add details to an existing reference without duplicating it, will be gradually rolled out to more wikis later this year. Wikis using the Reference Tooltips gadget are encouraged to update their version (typically at MediaWiki:Gadget-ReferenceTooltips.js as shown here) to ensure compatibility. Other reference-related gadgets may also be affected.
• All Wikinews editions will be closed and switched to read-only mode on 4 May 2026. Content will remain accessible, but no new edits or articles can be added. This closure was approved by the Board of Trustees of the Wikimedia Foundation following extended discussions. Read more.
• The Action API has had several formats for requested output. One of them, format=php, is being removed soon. Please ensure your scripts or bots use the JSON format. This removal should affect very few scripts and bots.
• The Special:NamespaceInfo page now includes namespace aliases. For example "WP" for the "Project" ("Wikipedia") namespace on the German Wikipedia.
• Detailed code updates later this week: MediaWiki

Weekly highlight

• Experienced editors are invited to test the Article guidance feature, designed to help less-experienced editors create well-structured, policy-compliant Wikipedia articles. Testing instructions are available. Also, after reviewing the outlines, please provide feedback on the project talk page. Based on your input, the feature will be refined and transferred to the pilot Wikipedias to translate and adapt. Check out the video explaining the feature.

Updates for editors

• On most wikis, all autoconfirmed users can now use Special:ChangeContentModel page to create new pages with custom content models, such as mass message lists, making custom page formats more accessible. Check Special:ListGroupRights for the status of your wiki.
• The Growth team has launched an account creation experiment to evaluate whether adding an account creation button to the mobile web header increases new account registrations and encourages more mobile users to contribute to the wikis. The experiment is currently live on Hindi, Indonesian, Bengali, Thai, and Hebrew Wikipedia, and targets 10% of logged-out mobile web users.
• View all 30 community-submitted tasks that were resolved last week. For example, an issue where VisualEditor could get stuck loading on Windows devices with animations turned off, has now been fixed.

Updates for technical contributors

• Starting later this week, Abuse filter editors who have the Improved Syntax Highlighting beta feature enabled will have CodeMirror instead of CodeEditor as the editor at Special:AbuseFilter. This is part of the broader effort to make the user experience more consistent across all editors.
• Tools and bots that access the Notifications API (action=query&meta=notifications) will need to update their OAuth or BotPassword grants to also include access to private notifications.
• Due to a library upgrade, listings on category pages may be displayed out of order starting on Monday, 20th April. A migration script will be run to correct this, and will take hours to days depending on the size of the wiki (up to a week for English Wikipedia).
• Detailed code updates later this week: MediaWiki

Weekly highlight

• After two years of development, Improved Syntax Highlighting, also known as CodeMirror 6, is to be promoted out of beta on Tuesday, April 21. It brings better code and wikitext readability, reduction in typing errors, and other benefits to all users of the standard syntax highlighter. A huge thank you to volunteer Bhsd who developed many of the new features, including code folding, autocompletion, and linting.
• A major update to the Wikipedia app for iOS is now rolling out, redesigning the interface to align with Apple's latest "Liquid Glass" visual design. Download the latest version and explore the update.

Updates for editors

• Reading lists is a feature which allows readers to save articles to a list for reading later. This feature is now in beta on Arabic, French, Indonesian, Vietnamese, and Chinese Wikipedias and by default for all new accounts on all Wikipedias.
• An experiment which explores extending Page Previews to mobile web will be launched in the week of April 20 on Arabic, English, French, Italian, Polish, and Vietnamese Wikipedias. Page Previews are pop-ups that display a thumbnail, lead paragraph, and a link to open the full article of a blue link, thereby improving content discovery. The feature is already available on desktop and in the apps. Read more about this experiment and others.
• On several wikis, logged-in editors who haven't confirmed their email addresses can now see a banner encouraging them to do so. Having the email address confirmed allows a user to restore access to the account if they lose it. Learn more.
• View all 15 community-submitted tasks that were resolved last week. For example, an issue where editing very large wiki pages in the 2017 wikitext editor caused slow loading, preview and scrolling lag, and performance issues when selecting, cutting, or pasting content, has now been fixed.

Updates for technical contributors

• As part of the promotion of CodeMirror from a beta feature, all users will use CodeMirror instead of CodeEditor for syntax highlighting when editing JavaScript, CSS, JSON, Vue and Lua content pages.
• The mirrors.wikimedia.org service for Debian and Ubuntu users will sunset and stop working on May 15. The resources for the service will be replaced with new and better options. Some users may need to switch to a different server which should take about a minute. You can read more.
• The image and oldimage table will be removed from wikireplicas. If your tools or queries access image or oldimage directly, please update them to use the file and filerevision table before 28 May.
• Following the recent implementation of global API rate limits on unidentified traffic, the Wikimedia Foundation will continue efforts to ensure fair use of infrastructure by applying global limits to identified API traffic beginning the last week of April. These limits are intentionally set as high as possible to minimise impact on the community. Bots running in Toolforge/WMCS or with the bot user right on any wiki should not be affected for now. However, all developers are advised to follow updated best practices. For more information, see Wikimedia APIs/Rate limits and Frequently Asked Questions.
• The Attribution API is now available as a beta. The API fetches information for crediting Wikimedia articles and media files wherever they are used. Reference documentation is available through the REST Sandbox special page available on all Wikimedia wikis (such as the REST sandbox on English Wikipedia). Share your feedback on the project talk page.
• There is no new MediaWiki version this week.
