I feel the need to get this out as soon as possible. If you’re running wordpress 3.3.2 I would highly suggest NOT upgrading to 3.4 yet.
I did a test install of 3.4 last night and while it seemed to work, the biggest problem was it didn’t allow tagging of posts. THIS IS A BIG ISSUE!
Wait for a fix and check that all of your plugins to make sure they’re 3.4 compatible before moving up!
It can / will end up screwing you up royally. When you do the upgrade, or when you’re ready to do the upgrade, BE CAREFUL. Do it in a test environment first.
