+<p>
+After several months spent making sure that a sufficient number of our
+downstreams is ready, we are now pleased to announce the release of Libav 9
+"Plain Nine".
+</p>
+
+<p>
+The first thing to note is that it is indeed 9, not 0.9. With this release, we
+change our versioning scheme to follow our workflow better.  This means that the
+leading zero, present in our previous version numbers, is dropped. Version
+numbers from now on will be in <i>major.minor</i> form, with major releases
+updating the major component and stable releases the minor component.
+</p>
+
+<p>
+A new library arrived in Libav during this development cycle -- its name is
+<b>libavresample</b> and it handles audio conversion and mixing. All
+users are encouraged to use it instead of the old, now deprecated, audio
+conversion API in libavcodec.
+</p>
+
+<p>
+The <b>libpostproc</b> library now resides in a separate tree. It was fully
+independent of the other Libav libraries, not used by any of the tools,
+and saw very little development. For these reasons we have decided that it
+has no place in Libav. A standalone Git tree is available
+at <a href="http://git.videolan.org/?p=libpostproc.git">VideoLAN</a> for
+people wishing to use libpostproc.
+</p>
+
+<p>
+The major versions of the <b>libavcodec</b>, <b>libavformat</b>
+and <b>libavfilter</b> libraries have been bumped, so they are not API
+or ABI compatible with the 0.8 release.
+</p>
+
+<p>
+This release brings a number of significant changes in
+the <b>libavfilter</b> library.  Firstly, all the API dealing with
+filter internals is no longer public. The result is that creating
+user-side filters will not be supported until libavfilter is more
+mature.  Secondly, full audio filtering support is now available along
+with a set of basic audio filters. We hope that their number will soon
+grow significantly.  The avconv transcoding tool has of course been
+extended to handle audio filtering as well.  There were a number of
+other API changes, most importantly the addition of the buffer sink
+public API.
+</p>
+
+<p>
+In the <b>libavcodec</b> library, one of the most notable changes is
+added support for planar audio (i.e. not interleaved). Many decoders and
+encoders, which previously did inefficient (de)interleaving internally,
+now <em>only work with planar audio formats</em>. Libavresample can be used for
+optimized conversion between interleaved and planar formats.
+</p>
+
+<p>
+Of big interest to our Windows users, Libav now supports building with the MSVC
+compiler. Since MSVC does not support C99 features used extensively by Libav,
+this has been accomplished using a <a
+href="https://github.com/libav/c99-to-c89/">converter</a> that turns C99 code
+to C89. See <a href="platform.html#Microsoft-Visual-C_002b_002b">here</a> for
+more detailed documentation on building Libav with MSVC.
+</p>
+
+<p>
+As usual, this release also contains support for some new formats, many
+smaller new features and countless bug fixes. We can highlight Opus
+decoding / encoding through libopus, encoders for Apple ProRes and Ut
+Video, 24-bit FLAC encoding, WMA Lossless and RealAudio Lossless decoders,
+fragmented MOV/MP4 and ISMV (Smooth Streaming) muxers, a large number of RTMP
+improvements and support for cover art in ID3v2, WMA, MP4 and FLAC.
