Ive been reading over the last few weeks that some addons arent supported so be forewarned if you lose some functionality of favorite utilities.
Didnt realise the release was so close so didnt take note of which ones. Must try and find the links....
edit..
Been reading the release notes and (of course, not that I think about it), functionality of addons is never guaranteed for future releases. I really must try and find the one I was looking at as someone had tested it on 1.5 beta and it didnt work and the addon author was uncontactable. Think it was that switchproxy one I was referring to a few posts back. Dont want to lose that!!!
