Upgrade time

The time has come, I believe to upgrade my site from the 2.6 version of Movable type to the 3.2 version. I’ve made a few personalizations to the 2.6 code base so support my specific features. I just wonder how difficult they will be to integrate into the new code base.
Features I added were not huge – inline comments (via a bit of AJAX), and a small HasComments tag.
Why am I upgrading? I’m the only author, and the free ediiton supports that. I want to do a little more theme work, and I’d like to get my added features out there in the community – I think they would be appreciated.
Not much else to talk about. I’m expecting job offers in the post any day now 🙂
