Erich Clar page

I want to include a synthetic reaction that is known as Clar's reaction. It is of a certain class of cyclic ketones that condense with themselves when heated to 400 C in a mixture of zinc dust and zinc chloride.

I will add references and a description of what it is used for in synthesizing new polycyclic aromatic hydrocarbons.

Tech News: 2026-24

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

• 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. [1]

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. [2]
• 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. [3]

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. [4]
• 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.
• Detailed code updates later this week: MediaWiki

Tech News: 2026-25

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

• 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. [5]

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. [6]
• View all 41 community-submitted tasks that were resolved last week.

Updates for technical contributors

• By the end of June, a valid user-agent string will be required for automated dumps downloads from the dumps.wikimedia.org website. 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.

Thank you!

Aah thank you so much for helping on the Trimethylolpropane triglycidyl ether article - I have basically no familiarity with chemistry and related areas, but I know that writing out certain things has to be done in particular ways. If I run into similar articles in future, where some element in a formula or technical name is being flagged as a type of error over here at the clean-up project, would it be okay to ask for your help if I'm unsure how to fix it? And/or is there a relevant project that you know of where I could also enlist help? Pikkupapupata ^💌 🌷 00:30, 21 June 2026 (UTC)

You're welcome to ping me if you have any questions or uncertain cases. WT:CHEMICALS is a fairly active community. DMacks (talk) 02:20, 21 June 2026 (UTC)

Awesome, cheers! Pikkupapupata ^💌 🌷 12:50, 21 June 2026 (UTC)
