I was noticing during my usual update that there's a 9.1 upgrade button.
I see that the forum has instructions here: http://ubuntuforums.org/showthread.php?t=1305158 and here http://www.ubuntu.com/getubuntu/upgrading
Now - is there sufficient need to upgrade from 9.04 to 9.1?
If I do this, will my apps break?
Any real-world experiences?
