Getting around to upgrading to MT 3.11 tonight. Hopefully there will be no hitches.
--Update--
Well, there was a hitch. I had a heck of a time just ftp'ing the files. Everything seems to be working now though.
--Update--
Ok, comments aren't quite working right. It keeps wanting me to approve every comment submitted and Typekey registration isn't working yet. (Fixed those, for the record, not deleting the mt-blacklist 1.64 files caused the first problem and the link for the Typekey token pointing to my home page rather than the mt directory caused the second.
Still a little trouble with comment pages redirecting to pages I don't want them to redirect to though... Probably have to go back and compare my current templates to the new 3.11 default templates
