A Beta phase generally begins when the software is feature complete but likely to contain a number of known or unknown bugs. Software in the beta phase will generally have many more bugs in it than completed software, speed or performance issues, and may still cause crashes or data loss.

What is the Hosting team’s recommendation to Hosting companies? Maintain, for now, PHP 7.4 as the default version for all WordPress, and test and report compatibility with PHP 8.0, 8.1 and 8.2, when available.

If you want to help the Hosting, Core, and Test teams, test new versions and future WordPress, PHP and SQL compatibility, you can use the tool WordPress Distributed Hosting Tests (Test Runner).
