I have not read the final rules but if they didn't change anything from the proposed ones then there's a number of key changes.
Combo FRS/GMRS radios won't be allowed any more
FRS expands to 22 channels, 2 watts, still license-free
GMRS licenses go to 10 year periods, like ham
GMRS will still share a few channels with FRS and can now use FRS 8-14 (467 MHz), albeit at 2W
GMRS will not adopt digital modes but limited text/location data will be allowed (e.g. the Garmin exemption)
GMRS can still use wide or narrow band
GMRS can still use repeaters
I don't see the point of making FRS radios anymore, other than not needing to apply for a license. It's not overall bad but it seems like the FCC could have simplified things by just combining the two services and distinguishing them by saying if you get a license you can use 50W, removable antennas, etc. If you don't want to be bothered then just use the 2W bubble pack radios.
