This adds the additional FRS channels (15-22) and expands on the GMRS channels to include updated bandwidth (though there's no way to specify 20kHz vs 25kHz). It also adds the GMRS repeater channels with the prescribed +5.0MHz offset (though you'll have to find the correct tones for your local GMRS repeaters).
This doesn't seem correct to me. FRS and GMRS both have 22 channels now (plus 8 of the GMRS channels can be used as repeater channels). The GMRS radio manufacturers are using the same channel numbering scheme as specified by the FCC for the FRS channels. So GMRS 1 through GMRS 22 would be a duplication of the 22 FRS channels plus the addition of the 8 GMRS repeaters channels making 30 total GMRS channels. The BTech GMRS-V1 is this way. The Midland GTX1000/1030/etc. series is this way (except it doesn't support repeaters). The only difference, not counting the repeater support, is that all FRS channels are narrow band but GMRS channels 15 - 22 can still use wide.
