Yes, i found the docu to it. It looks amazing for the webmailer improvements, and also the missing support of activesync from 3.3 should be a big stepp in the right direction.
I tried it out this weekend, and found some problems, some are major (like webserver brocken, no /SOGo website with openchange and UTF8 Errors in WebIF for German) but where should i post them?
I found the bugtracker but no bugs for 3.4, and the beta testing forum here is nearly unused. Am i doing something wrong?
