+   we like to brag the most about: features.
+
+   A lot of people will probably be happy to hear that we now have support for
+   NVENC — the Nvidia Video Encoder interface for H.264 encoding — thanks to
+   Timo Rothenpieler, with some little help from NVIDIA and Philip Langdale.
+
+   People in the broadcasting industry might also be interested in the first
+   steps of closed captions support with the introduction of a decoder by
+   Anshul Maheswhwari.
+
+   Regarding filters love, we improved and added many. We could talk about the
+   10-bit support in spp, but maybe it's more important to mention the addition
+   of colorlevels (yet another color handling filter), tblend (allowing you
+   to for example run a diff between successive frames of a video stream), or
+   the dcshift audio filter.
+
+   There are also two other important filters landing in libavfilter: palettegen
+   and paletteuse. Both submitted by the Stupeflix company. These filters will
+   be very useful in case you are looking for creating high quality GIFs, a
+   format that still bravely fights annihilation in 2015.
+
+   There are many other new features, but let's follow-up on one big cleanup
+   achievement: the libmpcodecs (MPlayer filters) wrapper is finally dead. The
+   last remaining filters (softpulldown/repeatfields, eq*, and various
+   postprocessing filters) were ported by Arwa Arif (OPW student) and Paul B
+   Mahol.
+
+   Concerning API changes, there are not many things to mention. Though, the
+   introduction of device inputs and outputs listing by Lukasz Marek is a
+   notable addition (try ffmpeg -sources or ffmpeg -sinks for an example of
+   the usage). As usual, see doc/APIchanges for more information.
+
+   Now let's talk about optimizations. Ronald S. Bultje made the VP9 decoder
+   usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+   Athlons can play 1080p 30fps VP9 content now), so we now secretly hope for
+   Google and Mozilla to use ffvp9 instead of libvpx. But VP9 is not the
+   center of attention anymore, and HEVC/H.265 is also getting many
+   improvements, which include C and x86 ASM optimizations, mainly from James
+   Almer, Christophe Gisquet and Pierre-Edouard Lepere.
+
+   Even though we had many x86 contributions, it is not the only architecture
+   getting some love, with Seppo Tomperi adding ARM NEON optimizations to the
+   HEVC stack, and James Cowgill adding MIPS64 assembly for all kind of audio
+   processing code in libavcodec.
+
+   And finally, Michael Niedermayer is still fixing many bugs, dealing with
+   most of the boring work such as making releases, applying tons of
+   contributors patches, and daily merging the changes from the Libav project.
+
+   A more complete Changelog is available at the root of the project, and the
+   complete Git history on http://source.ffmpeg.org.
+
+   We hope you will like this release as much as we enjoyed working on it, and
+   as usual, if you have any questions about it, or any FFmpeg related topic,
+   feel free to join us on the #ffmpeg IRC channel (on irc.freenode.net) or ask
+   on the mailing-lists.

-They use more space, can cause minor AV sync issues, require more
-CPU power to decode (unless the player has some decoded picture queue
