O frabjous day!
It's been a long, hard road since 2.3 was released but we finally made it! 2.4 is now available here and this is definitely the best, most awesomest release since, well, the last one (and given the amount of time and effort that's gone into it, ya'd bloody well hope so ).
If you haven't been keeping up with the betas, check out the updated feature list, tour and online help to see what's new. Detailed information about what's new can also be found in the release notes for each of the 2.3.x beta releases, just follow the links from here.
Callooh! Callay! Off to the pub I go...
