yes, apparently it does, according to a post in the Toontrack forums. There are no "read me" files that describe what's fixed...at least that I saw.
I noticed it removed my EZplayer Pro from my desktop and just made a EZD64 (I use 64 bit) as the .exe icon to launch it in stand alone. I have to use Toontrack solo to launch Superior in stand alone.
I had no problems, and only the EZD library had an update. So two update files probably for most people.
