Latest *tech news
<https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News>* from the
Wikimedia technical community. Please tell other users about these changes.
Not all changes will affect you. Translations
<https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/2026/33> are
available.

*Updates for editors*

   - A new ChartWizard is now available on Wikimedia Commons
   <https://commons.wikimedia.org/wiki/Special:ChartWizard/Data:Example.Pie.chart>
for
   users interested in creating charts from their own data. The wizard makes
   the Chart extension
   <https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:Chart> more
   beginner-friendly by allowing editors to create charts, such as bar and pie
   charts, without needing to use JSON. Users can still switch to the JSON
   editor if they prefer. Feedback on the new tool is welcome on the wish
   talk page <https://meta.wikimedia.org/wiki/Talk:Community_Wishlist/W414>.
   - View all 19 community-submitted tasks that were resolved last week
   <https://meta.wikimedia.org/wiki/Special:MyLanguage/Tech/News/Recently_resolved_community_tasks>.
   For example, an issue where the Wikipedia iOS app’s Picture of the Day
   widget displayed the same image every day instead of updating daily, has
   now been fixed. [1] <https://phabricator.wikimedia.org/T430692>

*Updates for technical contributors*

   - Math formula
   <https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:Math> SVG
   images will soon be generated in the browser instead of on the server.
   MathML continues to be generated on the server and renders in the browser
   without JavaScript. Wikibooks will see this change on 12 August, Wikisource
   on 19 August and Wikipedia from 20-27 August. You can try this by selecting
   "Client side MathJax rendering (for browsers with limited MathML support)"
   in your preferences. This change is part of deprecating RESTBase
   <https://www.mediawiki.org/wiki/Special:MyLanguage/RESTBase/deprecation>
    and deprecating Mathoid <https://phabricator.wikimedia.org/T431372>. [2]
   <https://phabricator.wikimedia.org/T271001>
   - Category pages will soon support sorting entries by the time they are
   added to a category. This will make it easier to find recently or
   long-standing categorized pages. It will also improve workflows for
   maintenance categories such as deletion backlogs and other time-based
   review tasks. You can use cldsort=timestamp URL argument in category
   view to sort the entries. [3] <https://phabricator.wikimedia.org/T433768>
   - Gadgets
   <https://www.mediawiki.org/wiki/Special:MyLanguage/Extension:Gadgets> and
   user scripts on Wikimedia wikis may now use ES2018 features
   <https://phabricator.wikimedia.org/T395347> and ES2019 features
   <https://phabricator.wikimedia.org/T419142> in JavaScript code.
   Previously, the platform only allowed up to ES2017. MediaWiki validates the
   source code to protect functionality from syntax errors and to ensure
   scripts are valid in all supported browsers
   <https://www.mediawiki.org/wiki/Special:MyLanguage/Compatibility#Browser_support_matrix>
   . [4] <https://phabricator.wikimedia.org/T419142>
