This is a full update, released through Test Flight for iOS and the Play Store test program for Android.
On the app it is labelled just “December '24” with version 24.12.0.
If all goes well, this will be published as the official December release tomorrow.
Is the star on the SPOTS signifying that the callsign is in my Callsign Notes file?
or Hams of Note?
or active callsign notes file?
The star is the default marker for callsign notes, if the line does not start with an emoji.
So it’s most likely a call from your personal notes file.
December update working fine on my Android 15 devices. 
Thanks for the report
