without what was here before to reference you're not going to be able to make a great comparison.
if you're in a forum view (not a thread view) you see more sort options at the bottom. there are a bunch of new features, some of them you haven't noticed yet.
bottom line is that the upgrades are a big pain in the ass. we need to do them, as each upgrade fixes security issues. they also add and change functionality. and they also break customizations that we have done for the board and we have to go back and fix them during the upgrade.
i know some people hate change, and they'll bitch about if you try to modify anything. some of the changes we don't really care for, some we like. there are also some new interface changes you guys are going to have to learn.
enjoy.
