Strategy to move to V16 from V15

Hi
Interesting to work through the changes / improvements / features of V16.

My perception is that , while moving from V13 / 14 to V15 was relatively
easy and smooth, it looks like one will have to be a bit more deliberate when moving
from V15 to V16.

Fortunately . some of the options have been made select able ( to choose legacy
behavior ) so that one can “opt-out” of the new behavior.
