Last night I upgraded from 1.3.1 to 1.4.1. The upgrade itself went smoothly.
After reboot I experienced the previously reported problem of having all the channels in our Sensor rack (ACN3 connect) cycle betsween full and off on about a 5 seconds. A deep clear fixed the problem. It may be triggered by exiting the Ion console app then returning to the console app from the maintenance shell.
On loading a saved show, none of the subs loaded on the universal fader wing. I took a guess that this was because 1.4.0 introduced the "universal" feature and set up the faders as subs, solving the problem. You may want to add a comment to the release notes to keep others from tripping over the change in behaviour since existing Ion users are used to the fader wings behaving as subs by default.
I haven't had much time to play with the new features but I really like the "group sub" feature on the fader buttons. Thanks to the development team for their efforts on what appears to be a really aggressive release schedule.
