Updates for editors

• Revise Tone helps newcomers identify passages in Wikipedia articles that may contain non-encyclopedic language and encourages them to consider revising the tone. The feature was A/B tested on the Arabic, English, French, and Portuguese Wikipedias, where newcomer task completion rates increased by 38.7% compared to the default Copyedit task, with no decrease in edit quality. The test ended on July 9, and the feature is now available for everyone on these wikis, configurable via Community Configuration. The plan is to release Revise Tone to more wikis.
• The community configuration that allows automatic removal of inactive mentors based on configurable criteria will be enabled on Thursday 16, on some wikis to keep mentor lists up to date. Mentors are experienced contributors who opt in to help new users on-wiki through the Growth Features. Administrators can now prepare the settings via Special:CommunityConfiguration/Mentorship; they will take effect starting Thursday.
• View all 38 community-submitted tasks that were resolved last week. For example, an issue where some users of the Wikipedia Android app were logged out immediately after signing in, preventing them from staying logged in and editing pages, has now been fixed.

Updates for technical contributors

• Editing a page via user scripts or gadgets was causing watchlist labels that the user had assigned to that page to reset. This has now been fixed.
• To work around a Safari bug (see phab:T425211), on Parsoid-enabled wikis, wikilink hrefs now use absolute urls instead of protocol-relative urls. REST API output remains unchanged and continue to use protocol-relative urls. Gadgets, user scripts, bots, and CSS might need to be adapted if they relied on the presence of protocol-relative urls in wikilink hrefs.
• Detailed code updates later this week: MediaWiki

In depth

• The Wikimedia Foundation’s Experiment Platform Team has published a blog post reflecting on its first year of structured experimentation. It highlights successful experiments such as Paste Check, Reference Check, and Tone Check, which improved editing outcomes and have been rolled out to more users, as well as experiments that did not lead to product changes.

Updates for editors

• The Reader Experience team has incorporated community feedback around the placement of watchstar and watchlist buttons for the Reading Lists beta feature, which would allow for saving articles for later reading – a wishlist item to bring the functionality to web. Editors are invited to enable the beta feature to test it out and share their thoughts.
• Suggestion Mode offers edit suggestions within the VisualEditor for improving Wikipedia articles. All suggestions are community-configurable. The TextMatch feature is a way for volunteers to create custom local suggestions. The feature searches in articles for strings of text, and now includes support for regular expressions. This gives volunteers greater precision and flexibility over the kinds of local suggestions they can create. Note: Suggestions can be targeted based on the edit count of the person editing as well as other aspects of the page. You can find examples from other communities for inspiration, including TextMatches that detect: typos, grammar-errors, potential advertisements, clichés, incorrect dash or hyphen usage, non-specific time keywords, outdated names, and more. Any feedback is appreciated.
• View all 27 community-submitted tasks that were resolved last week. For example, an issue where the SVG Translate tool could use an outdated version of a file, causing existing translations to be overwritten when new ones were uploaded, has now been fixed. Overall, in the last quarter from April – June 2026 about 337 community tasks were resolved by the Wikimedia Foundation.

Updates for technical contributors

• On Parsoid-enabled wikis, Parsoid now renders a maximum of 1,250 images per page. A new tracking category, "media-limit-reached", will be soon made available to identify pages where this limit is reached, making it easier to find content whose media output may have been restricted during rendering. See phab:T430854 for more information and to provide feedback.

Updates for editors

• Content Translation now supports dark mode, fulfilling a Community Wishlist request. This brings the tool in line with the accessibility features available in the Vector 2022 and Minerva skins, helping reduce visual fatigue for users translating content.
• DiscussionTools' source mode and the 2017 wikitext editor will now offer autocomplete for links ([[), templates ({{), HTML and parser tags (<), and magic words (__), making it quicker and easier to insert links, templates, and other wiki markup while editing.
• The Readers Growth team has concluded its experiment with mobile page previews and will not roll out the feature. Page Previews are a pop-up bottom sheet that appears when readers tap a blue link, showing a thumbnail, lead paragraph, and an option to open the article. The experiment showed flat retention and negative indicator metrics, suggesting that mobile web readers preferred navigating directly to linked articles rather than using page previews.
• The Reader Experience team has seen encouraging early results from the Reading Lists feature, with 93% of participating users reporting that it was useful. Reading Lists help active readers save articles for future reading and support their learning goals on Wikimedia projects. The team plans further improvements before expanding the feature to more users.
• The Explore Feed Refresh initiative was tested with new and casual Wikipedia app readers. The refreshed feed helps readers discover new and relevant content. After a 10.5% increase in engagement with the feed, Wikimedia Apps team has decided to scale the Home Feed redesign to iOS with the learnings from the Android release applied.
• View all 23 community-submitted tasks that were resolved last week. For example, an issue where subject names in the Article Guidance feature were displayed with incorrect capitalization on French Wikipedia, has now been fixed. Subject names will now follow the correct capitalization rules for the language.

Updates for technical contributors

• After running several Account Creation Experiments to improve registration completion rates, a new version of the username field on Create Account has been rolled out. It includes a popover summarizing the username policy to provide clearer guidance during account creation. As part of this change, the messages createacct-helpusername and createacct-username-help that several communities have configured will no longer be used. If communities want to customize the guidance shown in the new popover, they can instead edit the following messages: createacct-username-policy-popover-bullet1, createacct-username-policy-popover-bullet2, and createacct-username-policy-popover-bullet3.
• Later this week, the CodeMirror syntax highlighter will offer themes. The themes can be picked from a dropdown menu in the full CodeMirror preferences dialog. For wikitext, available themes are default, colorblind-friendly (previously the colorblind preference option on Special:Preferences#mw-prefsection-editing) and no-highlighting. For code languages (i.e., CSS/JavaScript/JSON/Vue/Lua), there are several themes available. These same themes will eventually be available for wikitext, too.
• From now on, wikis can restrict editing in the "User" namespace to only the page owner and certain user groups. Read the configuration documentation to learn more.

Updates for editors

• The Reader Experience team has developed a patch demo that wraps the page toolbar onto two lines when there is not enough horizontal space for all the buttons. This aims to reduce crowding in the Vector 2022 toolbar, which can occur on some language Wikipedias at certain screen widths.
• The Reader Experience team is planning to launch Reading Lists, a Community Wishlist item, which is currently available to try in beta, as a full feature in September. Before then, volunteer translator help is needed for string translations into a number of languages. The feature supports reading and learning goals on Wikipedia.
• Next week, the table of contents on Wikimedia Commons file pages will be improved by consolidating the file page table of contents with the page table of contents. This will make it easier to understand a file page’s structure, navigate to specific sections, and share links to individual sections.
• View all 24 community-submitted tasks that were resolved last week. For example, an issue where some TIFF images failed to load after clicking their thumbnail, causing a broken image to be displayed instead of the full-size image, has now been fixed.

Updates for technical contributors

• The variable and function selector in AbuseFilter has been updated to support search and autocomplete. It will allow filter maintainers to find the desired variable or function more quickly.
• The MJPEG and VP8 formats are removed from the video player. The MP4 format (MPEG-4 Part 2) is added instead, which provides higher quality videos to older iPhone devices. It may take a few weeks to retroactively update all existing videos. The default format for modern devices stays the same (VP9/WebM).
