Yes, No 1 same as Mr Anderton. A couple of other minor things...like I was working on one project and every time I add FabFilter Multiband to either the master track, or just a track, Sonar just crashed to the desktop. I tried this a few times with VST 2 and 3 and same result. However trialing it on a fresh project or template did not cause any problems...probably another vst conflict but has never happened like this before. 
 
The only other thing I've noticed is that I'll get these audio dropout messages after the project is idle for a maybe a few minutes. Doesn't happen during playback...only when left idle...bit weird as well. 

Hi. Besides one Vsti crashing for me (SONIVOX Orchestral String Companion), I have not had any issues with the latest update. 
All the best.

I'm running 2016.11 on Windows 10 latest update.  I posted last week of a problem I encountered when I installed the new update.  I had audio dropouts, needed to re-authorize my computer and re-scan all my VST plugs.
I beat the crap out of Sonar during my sessions.  I run between 24 to 120 tracks on each session with ProChannel and 3rd party plugs on every channel and bus.  Most files are created in ProTools or Logic and transferred to my Sonar session virtually always without a hiccup.
Since re-authorizing and re-scanning my system is back up and running, with a few quirks.  As long as I don't loop an 8 bar section while adjusting parameters within a plug in on the fly I'm good.  
Given the Herculean task this program performs, I'm confident bugs will be addressed.  So I will continue the updates.  
This user community is wonderfully supportive and extremely knowledgeable and if it is indeed a replacement for actual product support, so far so good.
 

I haven't had much use out of 2016/11 but am now on early access 2016/12 and it seems to be fine with the modest use I've had. The basics are all stable. Always a good sign.

When I had issues with 11 and after reading the posts, I just rolled back to 10.  I'll stay here until the final 12 comes out then I'll update it and see.  It's not like I never had crashes or glitches with 10... I've had them with every update, but we'll see if 12 is acceptable.

In both 11 & 12 Platinum updates, my 3rd party plugins have disappeared from the effects bin dropdown menu even thought they are registered in the plugin manager before & after a reset/rescan. they even show up in the effects bin on tracks in previously created projects. but, because they are not in the effects bin menu, I cannot add any new plugins to my projects. So, I've had to use windows restore points to get them back in the effects bin dropdown menus because (rollbacks don't fix the problem) once the updates have been installed. I have Sonar Artist on the same computer & it does not have this problem. Other than this one "Huge" issue, I have had no other problems with the new updates.

"In both 11 & 12 Platinum updates, my 3rd party plugins have disappeared"
This may explain why the StudioCat was loading Ozone 7 in existing projects, but I could not "find" it to insert
in a new project!
I re-scanned, checking I think, the "re-scan failed plugins", its a long shot, maybe you've already tried it.
I may have done this via Preferences>VST settings.
I know it was a WTF? moment and I was "digging" around scratching my head (this is Win7x64 btw).
HTH,
