I just noticed in another thread that 4.0.4 is available. I didn't even see it in the Announcements forum. Has anyone upgraded? I'm trying to figure out if I should upgrade to 4.5beta1, 4.0.4 or wait until 4.5 is officially released.
One feature I am waiting for is the ability to selectively set the from address, which is slated for 4.5 (though I don't know if it is in there yet).
