+              │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
+              └─────────────────────────────────────────────┘
+   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck".
+   A lot of important work got in this time, so let's start talking about what
+   we like to brag the most about: features.
+   A lot of people will probably be happy to hear that we now have support for
+   the 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.
+   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
+   eventually the dcshift audio filter.
+   There is also two other important filters landing in libavfilter: palettegen
+   and paletteuse, submitted by the Stupeflix company. These filters will be
+   very useful in case you are looking for creating high quality GIF, a format
+   that still bravely fights annihilation in 2015.
+   There are many other features, but now let's follow-up on one big cleanup
+   achievement: 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, not much things to mention. Thought, the
+   introduction of devices inputs and outputs listing is a notable addition
+   (try ffmpeg -sources or ffmpeg -sinks for an example of usage). See
+   doc/APIchanges for more information.
+   Now let's talk about optimizations. Ronald S. Bultje made the VP9 codec
+   usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+   Athlons can run 1080p 30fps VP9 content now), so we now secretely hope for
+   Google and Mozilla to use ffvp9 instead of libvpx.
+   But VP9 is not the center of attention anymore, and HEVC is also getting
+   many improvements, which includes optimizations, both in C and x86 ASM,
+   mainly from James Almer and Christophe Gisquet.
+   And finally, our Supreme Leader 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.
+   As usual, if you have any question on this release 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.
