WordPress 6.2 betaBetaBeta is the software development phase following alpha. 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. The focus of beta testing is reducing impacts to users, often incorporating usability testing.
IMPORTANT: WordPress 6.0 has beta support for PHP 8.0 and PHP 8.1. If used some of these versions may get some Warnings.
Versions prior to PHP 7.4 are not maintained by the PHP Community, although they may receive security updates from operating systems distributions. Security support for PHP 7.3 ended in 2021-12-06 which means that even if there are security problems with it, official versions won’t be released. Keeping your PHP to the latest stable version is important for WordPress speed and security.
