The latest version of WordPress is out for public use. This new version brings a long needed feature to the popular open source CMS, Site Health.
The new Site Health feature will start showing notices to administrators of sites that are running outdated versions of PHP, leading to potential security risks. It will also perform checks on new plugins to ensure that they are compatible with the existing version of PHP. If they are not, WordPress will prevent installation (and possible site breakage).
This is a big step in the right direction for WordPress and I'm hopeful that even more features are introduced to the Site Health feature as it matures.
Other improvements within this release include:
