After six months of development
The new release also introduces a new "Twenty Twenty" theme that is optimized to take advantage of the new features of the visual block editor and provides more flexibility when changing the look. Designers are offered features such as the new "Group" block to simplify the division of the page into sections. Support for fixed-width columns has been added to the Columns block. New predefined layouts have been added to simplify the intricate arrangement of content. For blocks, the ability to bind predefined styles is implemented.
Other new features include PHP 7.4 compatibility, support for auto-rotating images after upload (based on the mobile device's screen orientation at the time of the snapshot), advanced tools for detecting possible problems on the site (Health Check), and verification of the administrator's email address (required periodically to confirm the relevance of email, so as not to lose access in case of a change of address).
