Hi,
I believe it would be a nice idea to release a service pack to eliminate all bugs and errors discovered (and fixed) so far.
For those who have participated in beta testing program, it would be easier to get rid of known issues and concentrate on other unkown ones. Also, sometimes changing the code to fix a bug may cause a new bug to show up (this is a known issue in Microsoft Windows

).
Also, several people are joining this site and downloading beta version every week, and most of them reporting known issues again and again. With a service pack, it will not happen so frequently.
Just a thought.
Cheers.
