Most noticeable change is adding the Start window. While not offering anything that isn't possible in rest of the program, it does help speed-up opening of recently used files. Opening files in read-only mode also becomes possible and I'm sure this will be handy feature to many.
Fields have been refactored a bit; two-factor authentication and CVV buttons are hidden by default and former has gotten an option to show code instead of just copy.
Alongside a few minor fixes, feedback form has been moved to https. It just felt wrong to have password manager send messages via unencrypted channels. :)
