WordPress 5.9 was recently released. As was hinted in the BuddyPress 10.0 article, the most anticipated new feature in this new version of WordPress is full site editing. The Site Editor is a new feature to WordPress that allows block editor users to build their entire site with blocks. Unfortunately, full site editing is only available to content creators that are using a Block theme specifically designed to take advantage of the new feature.
Full Site Editing doesn't stand alone in WordPress as additional features and tools have been added for the site editor to come to life "out of the box" once version 5.9 is installed.
