Can someone please tell me the difference between HFP 1.7 and HFP 1.6 ? I am looking for differences in addition to what already mentioned in Wikipedia. Any link or document would be highly appreciated.

Version 1.6 adds optional support for wide band speech with the mSBC codec, a 16 kHz monaural configuration of the SBC codec mandated by the A2DP profile. Version 1.7 adds indicator support to report such things as headset battery level.
