WordPress 2.1 was released today and, unfortunately, I'm just not horribly impressed by the new feature list. Granted, it's a short feature list, but I see few reasons to upgrade. The main reason? Most of these features look like they're geared towards non-technical/shared-hosting users.
What is interesting? Akismet update - but I'm sure we can grab that without 2.1.
More efficient and faster database code? That's one.
Faster admin pages? Two.
The ability to denote more user categories - specifically to remove all rights from a user? Thr ... Nope, I don't see that.
