API changes, most recent first:
+2012-xx-xx - xxxxxxx - lavu 52.2.0 - audioconvert.h
+ Rename audioconvert.h to channel_layout.h. audioconvert.h is now deprecated.
+
+2012-xx-xx - xxxxxxx - lavu 52.1.0 - intmath.h
+ Add av_ctz() for trailing zero bit count
+
+2012-10-18 - xxxxxxx - lavu 51.45.0 - error.h
+ Add AVERROR_EXPERIMENTAL
+
+2012-10-12 - xxxxxxx - lavu 51.44.0 - pixdesc.h
+ Add functions for accessing pixel format descriptors.
+ Accessing the av_pix_fmt_descriptors array directly is now
+ deprecated.
+
+2012-10-xx - xxxxxxx - lavu 51.43.0 - aes.h, md5.h, sha.h, tree.h
+ Add functions for allocating the opaque contexts for the algorithms,
+ deprecate the context size variables.
+
+2012-10-xx - xxxxxxx - lavf 54.18.0 - avio.h
+ Add avio_closep to complement avio_close.
+
+2012-10-xx - xxxxxxx - lavu 51.42.0 - pixfmt.h
+ Rename PixelFormat to AVPixelFormat and all PIX_FMT_* to AV_PIX_FMT_*.
+ To provide backwards compatibility, PixelFormat is now #defined as
+ AVPixelFormat.
+ Note that this can break user code that includes pixfmt.h and uses the
+ 'PixelFormat' identifier. Such code should either #undef PixelFormat
+ or stop using the PixelFormat name.
+
+2012-10-05 - e7ba5b1 - lavr 1.0.0 - avresample.h
+ Data planes parameters to avresample_convert() and
+ avresample_read() are now uint8_t** instead of void**.
+ Libavresample is now stable.
+
+2012-09-24 - a42aada - lavc 54.28.0 - avcodec.h
+ Add avcodec_free_frame(). This function must now
+ be used for freeing an AVFrame.
+
+2012-09-12 - 8919fee - lavu 51.41.0 - audioconvert.h
+ Added AV_CH_LOW_FREQUENCY_2 channel mask value.
+
+2012-09-04 - 686a329 - lavu 51.40.0 - opt.h

+ Add codec descriptor properties AV_CODEC_PROP_LOSSY and
+ AV_CODEC_PROP_LOSSLESS.
+
+2012-08-18 - lavc 54.26 - avcodec.h
+ Add codec descriptors for accessing codec properties without having
+ to refer to a specific decoder or encoder.
+
+ c223d79 - Add an AVCodecDescriptor struct and functions
+ avcodec_descriptor_get() and avcodec_descriptor_next().
+ 51efed1 - Add AVCodecDescriptor.props and AV_CODEC_PROP_INTRA_ONLY.
+ 91e59fe - Add avcodec_descriptor_get_by_name().

+ Rename CodecID to AVCodecID and all CODEC_ID_* to AV_CODEC_ID_*.
+ To provide backwards compatibility, CodecID is now #defined as AVCodecID.
+ Note that this can break user code that includes avcodec.h and uses the
+ 'CodecID' identifier. Such code should either #undef CodecID or stop using the
+ CodecID name.
