After a small delay, PHP 8.2 was published in December 2022. The latest stable version 8.2.2 was published yesterday, 2nd of February. During the upcoming days an update will be introduced to Seravo’s hosting and upkeep, and 8.2 becomes available for developers. Roll on the weekend!
However, we don’t recommend upgrading to version to 8.2 just yet. As per usual, one should wait and let the WordPress core, plugin and theme updates catch up, so that they also will support the latest PHP version. In other words, we recommend PHP 8.2 for web development and testing purposes only, for now.
Upgrading may result in errors and broken websites, if the switch to 8.2 is done haphazardly or without necessary checks. We currently recommend PHP 8.0 for WordPress sites, or 8.1 if the site’s theme and plugins already support that. Take a look at our instructions for upgrading your site’s PHP version in Seravo’s Knowledge Bank!
