Maybe something else to add to the release notes - the new /etc/NetworkManager/* (I hate long names and caps - I know this is not UNIX, but one of the goals of UNIX was to keep things short, fewer key presses, and less output (the example given was IBM 'mainframe' that gave a page of text for a command that had no output - making it much easier to start the 'pipe' concept - only send the output) compared to /etc/network/* for configuring (static) interfaces.
imho a real pain - every distribution of Linux has a different way of doing things (although I am beginning to think it is a different version of Linux - change things because we can - because every distribution of Linux seems to be a different version of Linux).
Previous UNIX vendors would have been hung out to dry for this kind of 'change management (read mis-management). (imho).
