On the 12th of April, Beta 1 of WordPress version 6.0 became available for download and testing.
On the WordPress blog we were invited keep WordPress bug free; to help with testing.
Versions of Gutenberg included in WordPress 6.0 include 12.0.0 to 13.0.0, 24 releases since November 2021.
For more information on Gutenberg releases and the 10 new blocks see Gutenberg block change summary by version: from 12.1.0
One of the new features that I’d like to understand is the Webfonts API: Manage local fonts with PHP or theme.json.
