There seemed to be a few "missteps" with the 2017.2 release.  From what I've read those issues appear to have been cleared up?
 
Before I update I wanted to take the Official Release 2017.2 pulse here first?  What's your experience been with the new Official release update?

I installed the 2017.02 update last night and while doing some comping of audio tracks I noticed that the Smart Tool is intermittently not working.  I got multiple highlighted, (and sounding), clips at the same time.  I also could not get clips to highlight.  So far, clicking around randomly seems to fix it.  I'm going to roll back and see if there is a difference.
 
I'm also now getting that "clip transient" issue on close that I have not seen since last year.

I'm used to Sonar Pro crashing often, but since upgrading to 2017.2 my computer freezes completely in the middle of editing.No logs in the event viewer. Really annoying.

I started a new project this morning in the latest SPLAT update and could not import audio into the audio track. after multiple attempts, I thought that it might be due to the update. So, I rolled back to the January update and was able to import the file into a new project track. Has anyone else had this problem?

I had the same Smart Tool issue. Also couldn't control the Transport Module (play, stop, record, etc). I could control play/stop with space bar as normal.

Well I have not had issues with importing waves or mp3 files. No problems recording/mixing or using plugins.
I'm not have any real problems and I did install in mid project.
BUT there is a spike on cpu/core 1 and it is 90% higher then all other cpu cores.
This could be a problem for many things that appear to be unrelated.
Peace!

I've had weird graphical glitches. Open a project I created with the new update, no 3rd party plugins and only a couple of prochan modules on the master, tracks in track view briefly appear whilst project is loading then after loading the whole of track view is empty. I have to scroll the scroll bar to the right of track view to make them appear.
Also other glitches within the same project - mic audio was showing when track was armed but nothing recorded. Had to restart Sonar to sort this out.
 

in my case;I have issues with Sonar and my midi controllers; after removing my sonar artist and fadeport; Sonar somehow its more stable... 

I was reading this as the update was downloading.  I cancelled the update...until some people show up here who have not had any issues.

Being used to Sonar crashing all the time is not a normal condition. Why don't you open a new thread highlight your issues along with a brief rundown of your system specs and get some help.
