-              ┌─────────────────────────────────────────────┐
-              │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
-              └─────────────────────────────────────────────┘
+   The FFmpeg Project proudly presents FFmpeg 2.3 "Mandelbrot", a major
+   release with all the great features committed during the three-month period
+   since the release of FFmpeg 2.2.
 
-   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck", about 3
-   months after the release of FFmpeg 2.5.
+   In this release, there are lots of internal overhauls that make FFmpeg a
+   more accessible project for new developers. Many important new
+   optimizations and features like QTKit and AVFoundation input devices are
+   committed. Contributions done by Libav such as a new native Opus decoder
+   are also merged.
 
-   A lot of important work got in this time, so let's start talking about what
-   we like to brag the most about: features.
+   Because of the increasing difficulty to maintain and lack of maintainers,
+   we are very sorry to say that we have removed all Blackfin and SPARC
+   architecture assembly optimizations with the cleanups done. If you are
+   interested in maintaining optimization for these two architecture, feel
+   free to contact us and we will restore the code!
 
-   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.
+   Oh, and since this release, this modern-looking release note is provided in
+   addition to the old-style Changelog file, to make it easier for you to
+   focus on the most important features in this release.
 
-   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.
+   Enjoy!
 
-   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.
+   ┌────────────────────────────┐
+   │ *  API Information         │
+   └────────────────────────────┘
 
-   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.
+     FFmpeg 2.3 is completely source-compatible to the FFmpeg 2.2 series. There
+     are however some API deprecations that you need to take care of. Use `git
+     diff n2.2 n2.3 doc/APIchanges` to show the list of added and deprecated
+     APIs. FFmpeg 2.3 includes the following library versions:
 
-   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.
+       • libavutil      52.92.100
+       • libavcodec     55.69.100
+       • libavformat    55.48.100
+       • libavdevice    55.13.102
+       • libavfilter     4.11.100
+       • libswscale      2. 6.100
+       • libswresample   0.19.100
+       • libpostproc    52. 3.100
 
-   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.
+     Please refer to the doc/APIChanges file 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.
+   ┌────────────────────────────┐
+   │ New Optimization           │
+   └────────────────────────────┘
 
-   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.
+     We are excited to announce that we have committed new x86 assembly
+     optimization for HEVC, and FFmpeg's audio resampler libswresample. ARM
+     users will get a boost in MLP/TrueHD decoding thanks to new optimization.
+     Decoding Huffyuv also got a major boost from optimization on the C code.
 
-   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.
+     Of special interest for Microsoft Visual Studio users, we have also
+     converted some preexisting x86 assembly to NASM/Yasm format compatible
+     with MSVC setup, especially in the area of audio resampling.
 
-   A more complete Changelog is available at the root of the project, and the
-   complete Git history on http://source.ffmpeg.org.
+     Another major feature in this release is the introduction of AArch64
+     (ARMv8) assembly optimization. AArch64 is another name for the first
+     64-bit ARM architecture, used by Apple A7 SoC inside iPhone 5S. Some
+     32-bit ARM assembly has already been ported to AArch64, but more work is
+     underway.
 
-   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.
+   ┌────────────────────────────┐
+   │ Native Opus decoder        │
+   └────────────────────────────┘
+
+     Opus is an open audio format jointly developed by Xiph.Org, Mozilla,
+     Skype/Microsoft, and Broadcom. It combines the features of the Skype Cilk
+     speech codec and the Xiph.Org CELT music codec into one low-latency
+     codec. Decoding Opus is already possible since FFmpeg 1.0 using the
+     libopus library, but the new Opus native decoder brings a higher level of
+     stability and speed.
+
+   ┌────────────────────────────┐
+   │ QTKit and AVFoundation     │
+   └────────────────────────────┘
+
+     For OS X users, the new QTKit and AVFoundation devices allow you to use
+     the integrated camera on Macs. AVFoundation is a newer API only available
+     on OS X 10.7 "Lion" or newer. For users with older OS X systems, the
+     QTKit device using the older OS X API is for you.
+
+   ┌────────────────────────────┐
+   │ API Additions              │
+   └────────────────────────────┘
+
+     In this release, stream side data are introduced as AVStream.side_data as
+     a way to store miscellaneous stream-wide information. The format is
+     similar to the previously anonymous structure AVPacket.side_data (now
+     named as AVPacketSideData). With this change, audio ReplayGain
+     information and video rotation matrix are now exported through this API,
+     if available in the demuxer.
+
+     We also have improved libswresample's Doxygen API documentation, so new
+     developers wishing to use FFmpeg's excellent libraries can get started
+     more easily and faster.

 build is finished, but be sure to keep the main package.
 
-@section How do I make @command{pkg-config} find my libraries?
-
-Somewhere along with your libraries, there is a @file{.pc} file (or several)
-in a @file{pkgconfig} directory. You need to set environment variables to
-point @command{pkg-config} to these files.
-
-If you need to @emph{add} directories to @command{pkg-config}'s search list
-(typical use case: library installed separately), add it to
-@code{$PKG_CONFIG_PATH}:
-
-@example
-export PKG_CONFIG_PATH=/opt/x264/lib/pkgconfig:/opt/opus/lib/pkgconfig
-@end example
-
-If you need to @emph{replace} @command{pkg-config}'s search list
-(typical use case: cross-compiling), set it in
-@code{$PKG_CONFIG_LIBDIR}:
-
-@example
-export PKG_CONFIG_LIBDIR=/home/me/cross/usr/lib/pkgconfig:/home/me/cross/usr/local/lib/pkgconfig
-@end example
-
-If you need to know the library's internal dependencies (typical use: static
-linking), add the @code{--static} option to @command{pkg-config}:
-
-@example
-./configure --pkg-config-flags=--static
-@end example
-
-@section How do I use @command{pkg-config} when cross-compiling?
-
-The best way is to install @command{pkg-config} in your cross-compilation
-environment. It will automatically use the cross-compilation libraries.
-
-You can also use @command{pkg-config} from the host environment by
-specifying explicitly @code{--pkg-config=pkg-config} to @command{configure}.
-In that case, you must point @command{pkg-config} to the correct directories
-using the @code{PKG_CONFIG_LIBDIR}, as explained in the previous entry.
-
-As an intermediate solution, you can place in your cross-compilation
-environment a script that calls the host @command{pkg-config} with
-@code{PKG_CONFIG_LIBDIR} set. That script can look like that:
-
-@example
-#!/bin/sh
-PKG_CONFIG_LIBDIR=/path/to/cross/lib/pkgconfig

-@section I have a stretched video, why does scaling does not fix it?
-
-A lot of video codecs and formats can store the @emph{aspect ratio} of the
-video: this is the ratio between the width and the height of either the full
-image (DAR, display aspect ratio) or individual pixels (SAR, sample aspect
-ratio). For example, EGA screens at resolution 640×350 had 4:3 DAR and 35:48
-SAR.
-
-Most still image processing work with square pixels, i.e. 1:1 SAR, but a lot
-of video standards, especially from the analogic-numeric transition era, use
-non-square pixels.
-
-Most processing filters in FFmpeg handle the aspect ratio to avoid
-stretching the image: cropping adjusts the DAR to keep the SAR constant,
-scaling adjusts the SAR to keep the DAR constant.
-
-If you want to stretch, or “unstretch”, the image, you need to override the
-information with the
-@url{http://ffmpeg.org/ffmpeg-filters.html#setdar_002c-setsar, @code{setdar or setsar filters}}.
-
-Do not forget to examine carefully the original video to check whether the
-stretching comes from the image or from the aspect ratio information.
-
-For example, to fix a badly encoded EGA capture, use the following commands,
-either the first one to upscale to square pixels or the second one to set
-the correct aspect ratio or the third one to avoid transcoding (may not work
-depending on the format / codec / player / phase of the moon):
-
-@example
-ffmpeg -i ega_screen.nut -vf scale=640:480,setsar=1 ega_screen_scaled.nut
-ffmpeg -i ega_screen.nut -vf setdar=4/3 ega_screen_anamorphic.nut
-ffmpeg -i ega_screen.nut -aspect 4/3 -c copy ega_screen_overridden.nut
