+- fixed image polyphase bug (the bottom of some images could be
+  greenish)
+- added support for non clipped motion vectors (decoding only)
+  and image sizes non-multiple of 16
+- added support for AC prediction (decoding only)
+- added file overwrite confirmation (can be disabled with -y)
+- added custom size picture to H.263 using H.263+ (Juanjo)
+
+
+version 0.4.1:
+
+- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec
+  of AVI and ASF to DIV3.
+- added -me option to set motion estimation method
+  (default=log). suppressed redundant -hq option.
+- added options -acodec and -vcodec to force a given codec (useful for
+  AVI for example)
+- fixed -an option
+- improved dct_quantize speed
+- factorized some motion estimation code
+
+
+version 0.4.0:
+
+- removing grab code from ffserver and moved it to ffmpeg. Added
+  multistream support to ffmpeg.
+- added timeshifting support for live feeds (option ?date=xxx in the
+  URL)
+- added high quality image resize code with polyphase filter (need
+  mmx/see optimization). Enable multiple image size support in ffserver.
+- added multi live feed support in ffserver
+- suppressed master feature from ffserver (it should be done with an
+  external program which opens the .ffm url and writes it to another
+  ffserver)
+- added preliminary support for video stream parsing (WAV and AVI half
+  done). Added proper support for audio/video file conversion in
+  ffmpeg.
+- added preliminary support for video file sending from ffserver
+- redesigning I/O subsystem: now using URL based input and output
+  (see avio.h)
+- added WAV format support
+- added "tty user interface" to ffmpeg to stop grabbing gracefully
+- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences)
+  (Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>)
+- added MMX DCT from mpeg2_movie 1.5 (Juanjo)
+- added new motion estimation algorithms, log and phods (Juanjo)
+- changed directories: libav for format handling, libavcodec for
+  codecs
+
+
+version 0.3.4:
+
+- added stereo in MPEG audio encoder
+
+
+version 0.3.3:
+
+- added 'high quality' mode which use motion vectors. It can be used in
+  real time at low resolution.
+- fixed rounding problems which caused quality problems at high
+  bitrates and large GOP size
+
+
+version 0.3.2: small fixes
+
+- ASF fixes
+- put_seek bug fix
+
+
+version 0.3.1: added avi/divx support
+
+- added AVI support
+- added MPEG-4 codec compatible with OpenDivX. It is based on the H.263 codec
+- added sound for flash format (not tested)
+
+
+version 0.3: initial public release
