Most true MT nerds have seen this already, but Movable Type has issued a maintenance release.
Update May 30, 10:30 AM: I forgot that upgrading overwrites the search templates, which can be seen at the search page of this site. D'oh!
Update May 30, 3:40 PM: okay, that's fixed, and I modified my mt.cfg to have it load a different default template than the one in future upgrade packages, which should prevent future overwrites.
