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.

• 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 ⧼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).

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.

• 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.

• 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.
• 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.

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.

• 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.

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.

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.
• 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.

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.

• 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.

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.
• 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.

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.
• 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.

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.

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.
• Detailed code updates later this week: MediaWiki

Meetings and events

• On June 17th at 6pm UTC the WMF will be holding Discord call focused on a code review. We've heard through the Developer Satisfaction Survey that volunteers are struggling with code review and we'd like to discuss these experiences with the goal of surfacing workable solutions. You can join the call via the Wikimedia Community Discord server.
• The Latin American Wikimedia Conference will host a regional hackathon that will bring together the Wikimedia movement’s technical community including developers, system administrators, data scientists, and users with extended rights. Interested technical contributors can apply for a scholarship to participate until June 21 at midnight (Bolivia time, UTC-4).
• Sign up for Wikimania Team Challenges to join this special event. The Team challenges will take place online and in person from July 21 to 22, before Wikimania conference. Everyone is welcome, regardless of skills or Wikimania registration. Teams will work on 10 important challenges supporting the Wikimedia community. For details, visit the Team Challenges page and register there. Registration closes on June 20th at 11pm UTC.
