Hi,
I know this is a long overdue release. Problems will arise, no doubt about that, I'm expecting the most troubles with the new library format and its backward compatibility (since this is the very first release when it could be tested in the wild). Also the windows installer is showing some problems when installing over a previous installation.
I'm asking you to be patient and to be as much detailed as possible when reporting issues. More releases are coming soon.
Thanks!
