API changes, most recent first:

2010-11-21 - r25787 - lavcore 0.14.0 - audioconvert.h
Add a public audio channel API in audioconvert.h, and deprecate the
corresponding functions in libavcodec:
avcodec_get_channel_name()
avcodec_get_channel_layout()
avcodec_get_channel_layout_string()
avcodec_channel_layout_num_channels()
and the CH_* macros defined in libavcodec/avcodec.h.

2010-11-21 - r25777 - lavf 52.85.0 - avformat.h
Add av_append_packet().
