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, Edit filter managers who have the ⧼codemirror-beta-feature-title⧽ 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, ⧼codemirror-beta-feature-title⧽, 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.

Updates for editors

• There is a change in how new users are autoconfirmed that will improve anti-vandalism protection. Currently, users who have had an account for a few days and made a few edits are automatically added to the Autoconfirmed users group. This configuration tends to be exploited by some vandals, who create accounts and start to use them only after some time. To mitigate this, the configuration will be updated next week so that – for the purpose of becoming autoconfirmed – the account age will be counted from their first edit, instead of registration date. The numeric value of the age threshold will remain the same. This change will be deployed only to wikis which require at least one edit as part of the autoconfirmation conditions.
• All Wikipedia users with new accounts and those who activated the "automatically enable most beta features" option in their preference can now use the reading lists beta feature to save articles for later reading. This helps organize reading interests in one place for convenient access.
• View all 30 community-submitted tasks that were resolved last week. For example, the issue where infobox images have huge padding in Firefox, has been fixed.

Updates for technical contributors

• As a reminder, the global API rate limits will be applied this week to identified API traffic. This is to help ensure fair use of infrastructure. 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, including the actual rate limits, see Wikimedia APIs/Rate limits and Frequently Asked Questions.

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.
• 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.
• 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.

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.

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.

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.
• Detailed code updates later this week: MediaWiki
