Thunderbird 1.5 is out, finally

3 weeks after the release of Thunderbird 1.5 RC2, the final 1.5 release is finally out today! There are no official/unoffical announcements yet. I got this new from Wikipedia (What the…). Anyway, time to upgrade your email client. I tried auto-updating from 1.5 RC2 and no updates was found. So I assume that 1.5 final is identical to 1.5 RC2, right?
