Wikipedia:Tech news

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

• Reference Check has been deployed to English Wikipedia, completing its rollout across all Wikipedias. The feature prompts newcomers to add a citation before publishing new content, helping reduce common citation-related reverts and improve verifiability. In A/B testing, the impact was substantial: newcomers shown Reference Check were approximately 2.2 times more likely to include a reference on desktop and about 17.5 times more likely on mobile web.

Updates for editors

• The InterwikiSorting extension, which allowed for the sorting of interwiki links, has been undeployed from Wikipedia. As a result, editors who had enabled interwiki link sorting in non-compact mode (full list format) will now see links reordered. The links moving forward will be listed in the alphabetical order of language code.
• Later this week, people who are editing a page-section using the mobile visual editor, will notice a new "Edit full page" button. When tapped, you will be able to edit the entire article. This helps when the change you want to make is outside the section you initially opened.
• The Reader Experience team is inviting editors to assess whether dark mode should still be considered "beta" on their wiki, based on their experience of how well it functions on desktop and mobile. If the feature is deemed mature, editors can update the interface messages in MediaWiki:skin-theme-description and MediaWiki:Vector-night-mode-beta-tag to indicate that dark mode is ready and no longer considered beta.
• The improved Activity tab which displays user-insights is now available to all users of the Wikipedia iOS app (version 7.9.0 and later). Following earlier A/B testing that showed higher account creation among users with access to the feature, it has been rolled out to 100% of users along with some updates. The Activity tab now shows your edited articles in the timeline, offers editing impact insights like contribution counts and article view trends, and customization options to improve in-app experience for users.
• View all 21 community-submitted tasks that were resolved last week. For example, a bug that prevented DiscussionTools from working on mobile has now been fixed, restoring full functionality.

Updates for technical contributors

• The Global Watchlist lets you view your watchlists from multiple wikis on one page. The extension that makes this possible continues to improve. The latest upgrade is the inclusion of a new hook, ext.globalwatchlist.rebuild, which fires after each watchlist rebuild. This allows you to run gadgets and user scripts for the Special page.
• Detailed code updates later this week: MediaWiki

Weekly highlight

• Wikipedia 25 Birthday mode is now live on Betawi, Breton, Chinese, Czech, Dutch, English, French, Gorontalo, Indonesian, Italian, Luxembourgish, Madurese, Sicilian, Spanish, Thai, and Vietnamese Wikipedias! This limited-time campaign feature celebrates 25 years of Wikipedia with a birthday mascot, Baby Globe. When turned on, Baby Globe is shown on ~2,500 articles, waiting to be discovered by readers. Communities can choose to turn Birthday mode on by getting consensus from their community and asking an admin to enable the feature and customize it via community configuration on the local wiki.

Updates for editors

• Sub-referencing, a new feature to re-use references with different details has been released to Swedish Wikipedia, Polish Wikipedia and a couple of other wikis. You can try the feature on these projects or on testwiki and betawiki. Learnings from the first pilot wiki German Wikipedia have been published in a report. Reach out to the Wikimedia Deutschland team if you are interested in becoming a pilot wiki.
• Paste Check will become available at all Wikipedias this week. The feature prompts newcomers who are pasting text they are not likely to have written into VisualEditor to consider whether doing so risks a copyright violation. Paste Check tags all edits where it is shown for potential review. Local administrators can configure various aspects of the feature via Special:EditChecks. Research across 22 wikis found that Paste Check resulted in an 18% decrease in relative reverted-edits compared to the control group. Translators can help to localize this and related features.
• The Reader Experience team will be standardizing the user menu in the top right for all mobile users so that it is closer to the desktop experience. Currently this user menu is only visible to users with Advanced Mobile Controls (AMC) turned on. The only change is that a couple buttons previously in the left-side menu will move to the top right for users who do not have AMC turned on. This change is expected to go out March 9 and seeks to improve the user interface.
• Starting in the week of March 2, the emails sent out when an email address was added, removed, or changed for an account will switch to a substantially nicer and clearer HTML email from the prior plaintext one.
• Notifications are currently limited to 2,000 historic entries per user, and extend back to 2013 when the feature was released. This is going to be changed to only store Notifications from the last 5 years, but up to 10,000 of them. This will help with long-term infrastructure health and help to prevent more recent notifications from disappearing too soon.
• The Global Watchlist which lets you view your watchlists from multiple wikis on a single page continues to see improvements. The latest update improves label usage experience. The extension now allows activating the language fallback system for Wikidata items without labels in the viewed language, and showing those labels in the user’s preferred Wikidata language if no uselang= URL parameter is provided.
• The Wikipedia Android team has started a beta test of hybrid search on Greek Wikipedia. Hybrid search capabilities can handle both semantic and keyword queries enabling readers to find what they’re looking for directly on Wikipedia more easily.
• For security reasons, members of certain user groups are required to have two-factor authentication (2FA) enabled. Currently, 2FA is required to use the group, but not to be a member of it. Given that this model still has some vulnerabilities, the situation will gradually change in March. Members of these groups will be unable to disable 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 second half of March, users without 2FA will be removed from these groups. This applies to: CentralNotice administrators, checkusers, interface administrators, suppressors, Wikidata staff, Wikifunctions staff, WMF Office IT and WMF Trust & Safety. Nothing will change for other users. See the linked task for deployment schedule.
• View all 27 community-submitted tasks that were resolved last week. For example, the issue preventing users from creating an instance in Wikibase.cloud has now been fixed.

Updates for technical contributors

• To help ensure fair use of infrastructure, over the next month the Wikimedia Foundation will implement global API rate limits across our APIs. In early March, stricter limits will be applied to unidentified requests from outside Toolforge/WMCS and API requests that are made from web browsers. In April, higher limits will be applied to identified traffic. 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.
• The Wikidata Query Service Linked Data Fragment (LDF) endpoint will be decommissioned in February. This endpoint served limited traffic, which was successfully migrated to other data access methods that were better suited to support existing use cases. The hardware used to support the LDF endpoint will be reallocated to support the ongoing backend migration efforts.
• The new Parsoid parser continues to be deployed to additional wikis, improving platform sustainability and making it easier to introduce new reading and editing features. Parsoid is now the default parser on 488 WMF wikis (268 Wikipedias), now covering more than 10% of all Wikipedia page views.
• The process and criteria for requesting exceptional access to the high volume feed of the Wikimedia Enterprise APIs (at no cost for mission-aligned usecases), have now been published. This is to provide more thorough and clearer documentation for users.
• Tech Blog, the blog dedicated to the Wikimedia technical community will be migrating to Diff, the community news and event blog. The migration should be complete in April 2026, after which new posts will be accepted for publishing. Readers will be able to access posts – old and new – on the landing page at https://diff.wikimedia.org/techblog.

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

In depth

• 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
