-* `libavfilter` provides a mean to alter decoded Audio and Video through chain of filters.
-* `libavdevice` provides an abstraction to access capture and playback devices.
-* `libswresample` implements audio mixing and resampling routines.
-* `libswscale` implements color conversion and scaling routines.
+  You can also view it online at http://ffmpeg.org/documentation.html
 
-## Tools
+2) Licensing

+ └───────────────────────────────────────────┘
 
-   The FFmpeg Project proudly presents FFmpeg 2.5 "Bohr", 2.5 months after the
-   release of 2.4.
+   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 most important new features are AVFoundation screen-grabbing support,
-   animated WebP decoding support, and Animated PNG support. In addition, many
-   exciting features for video streaming are also implemented, including MPEG-
-   DASH fragmenting muxer, HEVC RTP payload muxer, and UDP Lite support.
+   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.
 
-   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).
+   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!
+
+   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.
+
+   Enjoy!

+   │ New Optimization           │
+   └────────────────────────────┘
 
+     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.
 
-     Please refer to the doc/APIchanges file for more information.
+     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.
+
+     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.
+
+   ┌────────────────────────────┐
+   │ 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

+   │ 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.
