On the page that Robricc is providing, 3.91 is posted as a "stable" version. Looking at the release notes only minor adjustments have been made anyway.
BTW, anybody tried yet if the --nogap feature has matured since the last release?

I haven't tried it yet and I'm not going to (on XP that is - I will use it with 2000), because I'm going to reinstall my system today with win 2000. Damn I really hate XP, I wish I never bothered with it.
