Dear all,
The SRE team is pleased to share that since January we have been gradually migrating the WMF MediaWiki production environment to PHP 8.1! This upgrade from PHP 7.4 brings performance improvements, security enhancements, and access to newer language features that will help to ensure long-term stability and maintainability. You can find more information in the PHP release announcements[0]. Key points - API and Web traffic will be running entirely on PHP 8.1 by the end of March[1] - If you maintain extensions or tools, please ensure they are compatible with PHP 8.1. - If you encounter issues that you believe are triggered by the migration to PHP 8.1, we encourage you to open a subtask[2]. - If the issue is urgent and/or widespread, you can escalate directly to SRE via the #wikimedia-sre channel on IRC. Thanks to everyone who contributed to this long-running effort to prepare both MediaWiki and our production environment for this transition. Special appreciation goes to the developers who reported and resolved any bugs and production issues along the way—your efforts have been invaluable in moving forward this migration according to plan. If you have any questions or concerns, please add your comments on Phabricator under the relevant tasks[1][3] Best Regards, Scott French & Effie Mouzeli On Behalf of the SRE team [0] (Release Announcement) https://www.php.net/releases/8.0/en.php and https://www.php.net/releases/8.1/en.php [1] (MediaWiki on PHP 8.1 production traffic ramp-up) https://phabricator.wikimedia.org/T383845 [2] (PHP 8.1 issues found during WMF rollout/ramp up) https://phabricator.wikimedia.org/T379874 [3] (Migrate WMF production from PHP 7.4 to PHP 8.1) https://phabricator.wikimedia.org/T319432
