Query about not implemented features in Bluez x.yy version

Hi All,

I have question about finding out what core features are not implemented in any given version of BlueZ.
By core features, I mean mandatory and optional PICS in L2CAP,GAP,RFCOMM,SDP,SPP sections.

For example, how to know what features are implemented and not implemented in BlueZ 4.32  and/or 4.46 ?

In general , how to know which features are implented or not in version X.YY of BlueZ? Will there
be any consolidated release notes document or browsing source code is the only method to judge this?


Regards,
Vikram
