I noticed that after the update I don't seem to be getting S-Meter readings from my 3rd party apps (HRD, Smartmeter) maybe I'm just missing something.
For example when a run HRD everything seems to work except the S-Meter?

OK, I have the answer.  Since CAT is no longer restricted to Slice A, the command syntax changed.
Previously the syntax was  ZZSM0; for the vfoA meter reading.  The ZZSM CAT command no longer has an argument (the zero).  In the test box for the CAT command, if you enter ZZSM; it will return the meter reading for the slice that CAT port is associated with.

You will need to contact HRD and the SmartMeter developers and let then know that the ZZSM CAT command syntax has changed.
