i did the upgrade to 20141120 this morning
no problems
only the Nvidia driver i had to install again “the hard way”
Your timing was good. The 20141120 update applied here yesterday was around 400 packages, and no new issues so far.
updated ok on kabel i/f
was forced to re-enter wireless password on first attemp at networking
no other anomalies noticed
It seems to be OK, too.
