As you can see at https://community.embarcadero.com/blogs/entry/rad-studio-10-2-2-released-today, the new version 10.2.2 of Delphi, C++Builder, and RAD Studio is now available.
The new features are covered in the docWiki, at http://docwiki.embarcadero.com/RADStudio/Tokyo/en/10.2_Tokyo_-_Release_2
There are hundreds of bugs fixed (including over 150 bugs reported by customers in Quality Portal), as you can read in List of new features and customer reported issues fixed in RAD Studio 10.2 Tokyo Release 2 (we'll close the matching QP report in the coming days).
In the coming days I and the other PM will write a few blog posts on specific features added to the product. Also, there is a webinar on Thursday you can sign up for (at 3 times in the day). It will be an introduction to 10.2.2. Follow one of the 3 links at: https://community.embarcadero.com/index.php/all-events?language=en-GB&sort=embevent.
