This module describes porting from FLAC 1.1.4 to FLAC 1.2.0.

There were only very minor changes to the interfaces from 1.1.4 to 1.2.0. In libFLAC, FLAC__format_sample_rate_is_subset() was added. In libFLAC++, FLAC::Decoder::Stream::get_decode_position() was added.

Finally, value of the constant FLAC__FRAME_HEADER_RESERVED_LEN has changed to reflect the conversion of one of the reserved bits into active use. It used to be 2 and now is 1. However the FLAC frame header length has not changed, so to skip the proper number of bits, use FLAC__FRAME_HEADER_RESERVED_LEN + FLAC__FRAME_HEADER_BLOCKING_STRATEGY_LEN
