DVR 522 L1.60 Software upgrade. What did it do?

[AppliedAggression]

This was a huge jump in software numbers, are there any major differences?

It did clear up some problems but now my 721 has been rebooting every time I have back to back timers fire late at night. I also have troubles with PIP when timers fire.

I haven't seen any improvements on my 522 with 160.
