"SONAR will now place newly recorded clips into existing Take lanes during loop recording or whenever possible"
 
I MUST be totally misreading this.  I hope this isn't what I think it is.  Currently, I will set up a loop and record multiple takes each in it's own lane.  When I'm done I'll audition each of the take lanes and pick the one I like the best.  Please tell me that Sonar will NOT overwrite each take lane while looping just to keep take lanes more manageable.  That would cripple my work flow beyond repair.

I really hope that's an option we can disable.

It doesn't overwrite anything. As I understand it, this eliminates the issue that happened if you, for example, do comping on the first verse and generate, say, 10 Take lanes. Then if you started comping on the second verse and also used 10 Take lanes, SONAR would not use the existing Take Lanes even though they would be empty where the second verse started...it would create new Take Lanes so now your track would have 20 take lanes or whatever. With this change, because the 10 Take lanes were empty where the second verse started, SONAR would simply record into those.

That`s the way I read it too :) 

This new behavior sounds like something I've been wanting for some time. Looking forward to it!

I hope Craig's right. I often record vocals and especially guitar leads by section and it's a hassle to keep moving clips to available lanes and keep deleting an ever mounting number of take lanes.

The Reuse feature in the comping update in [2017.02] is only one of several significant improvements.
 
Here is an example of the new comping followed by an example of the same project using the old comping.  Instead of 7 lanes to display the recording takes, the new method only uses 4 lanes.

Most excellent. This is a HUGE improvement and I am so looking forward to this!

I'm not seeing 2017.02 when I try to roll back...
 

Also, don't overlook the ability to now maximize take lanes in the same way we can maximize tracks by double clicking on them.  This should please a lot of people who have felt constrained by the limited take lane height in the past.
