I'm looking for a definitive answer on what each compatibility level means.

Specifically, I'm looking for:

- new features

- deprecated features

- removed features

We're on 4.3 so I'm looking for the info above on 4.4, 4.5 and 4.6

My main motivation is to ensure we don't lose SPICE support.

We actually use RHV and I logged a case with Red Hat GSS but couldn't get the info I was after.

Thanks
