I think generally the 2016.03 version is stable.  You can always roll back if you find a bug that destroys your workflow.

Updating is kind of like jumping into a swimming pool without checking the water temperature first. Where updating differs is if you find the temperature is indeed too cold, you can unjump.

Insert also doesn't move meter changes or tempo changes.   My work around is a little scary, because you are deleting your work, but ...     select all the time range from your insert point to the end, select all tracks, use "cut special" and select markers and meter and tempo changes (do not select 'delete hole').     Then, making sure the topmost track is the 'focus' track, go to where you want the material to be (as in, if you are inserting two measures, change now time to where it was plus 2)  and use paste. 
 
Then, to avoid other mysterious bugs, select all the midi tracks again and run 'bounce to clips'.   (track view, Clips, option)
 

Sorry, but to say meter & tempo changes don't move when inserting measures is, in my experience, completely wrong & misleading.
 
I have NEVER had any problem with this function in all versions of sonar from 6PE onwards.
 
I'd love to be sat over your shoulder when you're working.......
