Hey all! (first post

)
I for a couple of months ago installed Xcode 2.0 (the version that came bundled with the Tiger DVD). I just recently noticed there were a 2.2 version available of Xcode so I thought I'd just update my 2.0 install to 2.2. Why run old software anyway?
So my question is: is it safe to install 2.2 over 2.0 or do I have to do some advanced uninstalling off 2.0 before I install 2.2?
TIA
Peter
