  "textContent": "Latest **tech\nnews** from the Wikimedia technical community. Please tell other users about these changes. Not all changes will affect you. Translations are available.\n\n**Weekly highlight**\n\n  * After two years of development, Improved\nSyntax Highlighting, also known as CodeMirror\n6, 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\nfolding, autocompletion, and linting. [1]\n  * 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\nversion and explore the update.\n\n\n\n**Updates for editors**\n\n  * \nReading 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.\n  * An experiment which explores extending Page\nPreviews 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\nmore about this experiment and others.\n  * On several wikis, logged-in editors who haven’t confirmed\ntheir 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\nmore. [2]\n  * View all 15 community-submitted tasks that were resolved\nlast 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. [3]\n\n\n\n**Updates for technical contributors**\n\n  * 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. [4]\n  * 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\nmore. [5]\n  * 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. [6]\n  * Following the recent implementation of global API rate limits on unidentified traffic, the Wikimedia Foundation will continue efforts to ensure fair\nuse 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\nAPIs/Rate limits and Frequently\nAsked Questions.\n  * The Attribution\nAPI 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\nWikipedia). Share your feedback on the project talk\npage.\n  * There is no new MediaWiki version this week.\n\n\n\n_**Tech\nnews** prepared by Tech\nNews writers and posted by bot • Contribute • Translate • Get\nhelp • Give\nfeedback • Subscribe\nor unsubscribe._",
