The other thing I note is, that while yes I accept there was a red warning in the install message, I can't remember what the last update I did looked like, so for all I remember there was a red warning in those too. (I am assuming there wasn't). Which is why I think people should have been forced to come to the nexus website to install the update or had some sort of window pop up that shouts "this may cause problems with your install" and a 30 second count down timer or some such. Versions that cause significant changes need something that alters the basic install method to prompt people to realise something is different. *obligatory raging message here*
