For example, people may have a MixMonitor post-processing script that they run that always assumes a file exists - regardless of its size - after a call has terminated.  You may want to update the UPGRADE notes reflecting the change in behavior.

I don't think so.  This is incredibly minor change in behavior that - as far as I can see - would only be a problem if you were relying on a quirk of MixMonitor for an external script.

A notice in UPGRADE.txt would be sufficient, in my opinion.

This has the effect of leaving empty audio files behind.
