I was already running the Gutsy testing version, but still got a note telling I could update. The update itself worked flawlessly, but also installed a lot of programs that are default in Gutsy, but I didn't want. Perhaps this is intentional, but I have already chosen a set of programmes I want to use myself, and I'm not waiting for additional programmes. Maybe next time add an option to ask what programmes the user wants to install when upgrading? It could be combined with a dialogue that shows what the new features of (K)ubuntu are (like the announcement on the website), with checkboxes next to them to allow the user to select the features he / she wants to install.
