REM commands with the list set to the Forward List (FL) with a group ID only removes that user from the respective group, not the Forward List (FL) itself.
ADD commnads with the list set to the Forward List (FL) with a group ID only adds that user from the respective group, and the Forward List (FL) if the user is not already in the Forward List (FL).
SYN now includes LSG entries for groups.
LST (either from itself or a SYN response) now includes contact group numbers for the Forward List (FL).
