+-Next Release
+-  - Incompatible changes:
+-    The AV1 encoder's default keyframe interval changed to 128 from 9999.
+-    Support for armv6 was removed.
++2018-06-28 v1.0.0
++  AOMedia Codec Workgroup Approved version 1.0
+ 
+ 2016-04-07 v0.1.0 "AOMedia Codec 1"
+   This release is the first Alliance for Open Media codec.
+-2015-11-09 v1.5.0 "Javan Whistling Duck"
+-  This release improves upon the VP9 encoder and speeds up the encoding and
+-  decoding processes.
+-
+-  - Upgrading:
+-    This release is ABI incompatible with 1.4.0. It drops deprecated VP8
+-    controls and adds a variety of VP9 controls for testing.
+-
+-    The vpxenc utility now prefers VP9 by default.
+-
+-  - Enhancements:
+-    Faster VP9 encoding and decoding
+-    Smaller library size by combining functions used by VP8 and VP9
+-
+-  - Bug Fixes:
+-    A variety of fuzzing issues
+-
+-2015-04-03 v1.4.0 "Indian Runner Duck"
+-  This release includes significant improvements to the VP9 codec.
+-
+-  - Upgrading:
+-    This release is ABI incompatible with 1.3.0. It drops the compatibility
+-    layer, requiring VPX_IMG_FMT_* instead of IMG_FMT_*, and adds several codec
+-    controls for VP9.
+-
+-  - Enhancements:
+-    Faster VP9 encoding and decoding
+-    Multithreaded VP9 decoding (tile and frame-based)
+-    Multithreaded VP9 encoding - on by default
+-    YUV 4:2:2 and 4:4:4 support in VP9
+-    10 and 12bit support in VP9
+-    64bit ARM support by replacing ARM assembly with intrinsics
+-
+-  - Bug Fixes:
+-    Fixes a VP9 bitstream issue in Profile 1. This only affected non-YUV 4:2:0
+-    files.
+-
+-  - Known Issues:
+-    Frame Parallel decoding fails for segmented and non-420 files.
+-
+-2013-11-15 v1.3.0 "Forest"
+-  This release introduces the VP9 codec in a backward-compatible way.
+-  All existing users of VP8 can continue to use the library without
+-  modification. However, some VP8 options do not map to VP9 in the same manner.
+-
+-  The VP9 encoder in this release is not feature complete. Users interested in
+-  the encoder are advised to use the git master branch and discuss issues on
+-  libvpx mailing lists.
+-
+-  - Upgrading:
+-    This release is ABI and API compatible with Duclair (v1.0.0). Users
+-    of older releases should refer to the Upgrading notes in this document
+-    for that release.
+-
+-  - Enhancements:
+-      Get rid of bashisms in the main build scripts
+-      Added usage info on command line options
+-      Add lossless compression mode
+-      Dll build of libvpx
+-      Add additional Mac OS X targets: 10.7, 10.8 and 10.9 (darwin11-13)
+-      Add option to disable documentation
+-      configure: add --enable-external-build support
+-      make: support V=1 as short form of verbose=yes
+-      configure: support mingw-w64
+-      configure: support hardfloat armv7 CHOSTS
+-      configure: add support for android x86
+-      Add estimated completion time to vpxenc
+-      Don't exit on decode errors in vpxenc
+-      vpxenc: support scaling prior to encoding
+-      vpxdec: support scaling output
+-      vpxenc: improve progress indicators with --skip
+-      msvs: Don't link to winmm.lib
+-      Add a new script for producing vcxproj files
+-      Produce Visual Studio 10 and 11 project files
+-      Produce Windows Phone project files
+-      msvs-build: use msbuild for vs >= 2005
+-      configure: default configure log to config.log
+-      Add encoding option --static-thresh
+-
+-  - Speed:
+-      Miscellaneous speed optimizations for VP8 and VP9.
+-
+-  - Quality:
+-      In general, quality is consistent with the Eider release.
+-
+-  - Bug Fixes:
+-      This release represents approximately a year of engineering effort,
+-      and contains multiple bug fixes. Please refer to git history for details.
+-
+-
+-2012-12-21 v1.2.0
+-  This release acts as a checkpoint for a large amount of internal refactoring
+-  and testing. It also contains a number of small bugfixes, so all users are
+-  encouraged to upgrade.
+-
+-  - Upgrading:
+-    This release is ABI and API compatible with Duclair (v1.0.0). Users
+-    of older releases should refer to the Upgrading notes in this
+-    document for that release.

+-
+-
+-2012-05-09 v1.1.0 "Eider"
+-  This introduces a number of enhancements, mostly focused on real-time
+-  encoding. In addition, it fixes a decoder bug (first introduced in
+-  Duclair) so all users of that release are encouraged to upgrade.
+-
+-  - Upgrading:
+-    This release is ABI and API compatible with Duclair (v1.0.0). Users
+-    of older releases should refer to the Upgrading notes in this
+-    document for that release.
+-
+-    This release introduces a new temporal denoiser, controlled by the
+-    VP8E_SET_NOISE_SENSITIVITY control. The temporal denoiser does not
+-    currently take a strength parameter, so the control is effectively
+-    a boolean - zero (off) or non-zero (on). For compatibility with
+-    existing applications, the values accepted are the same as those
+-    for the spatial denoiser (0-6). The temporal denoiser is enabled
+-    by default, and the older spatial denoiser may be restored by
+-    configuring with --disable-temporal-denoising. The temporal denoiser
+-    is more computationally intensive than the spatial one.
+-
+-    This release removes support for a legacy, decode only API that was
+-    supported, but deprecated, at the initial release of libvpx
+-    (v0.9.0). This is not expected to have any impact. If you are
+-    impacted, you can apply a reversion to commit 2bf8fb58 locally.
+-    Please update to the latest libvpx API if you are affected.
+-
+-  - Enhancements:
+-      Adds a motion compensated temporal denoiser to the encoder, which
+-      gives higher quality than the older spatial denoiser. (See above
+-      for notes on upgrading).
+-
+-      In addition, support for new compilers and platforms were added,
+-      including:
+-        improved support for XCode
+-        Android x86 NDK build
+-        OS/2 support
+-        SunCC support
+-
+-      Changing resolution with vpx_codec_enc_config_set() is now
+-      supported. Previously, reinitializing the codec was required to
+-      change the input resolution.
+-
+-      The vpxenc application has initial support for producing multiple
+-      encodes from the same input in one call. Resizing is not yet
+-      supported, but varying other codec parameters is. Use -- to
+-      delineate output streams. Options persist from one stream to the
+-      next.
+-
+-      Also, the vpxenc application will now use a keyframe interval of
+-      5 seconds by default. Use the --kf-max-dist option to override.
+-
+-  - Speed:
+-      Decoder performance improved 2.5% versus Duclair. Encoder speed is
+-      consistent with Duclair for most material. Two pass encoding of
+-      slideshow-like material will see significant improvements.
+-
+-      Large realtime encoding speed gains at a small quality expense are
+-      possible by configuring the on-the-fly bitpacking experiment with
+-      --enable-onthefly-bitpacking. Realtime encoder can be up to 13%
+-      faster (ARM) depending on the number of threads and bitrate
+-      settings. This technique sees constant gain over the 5-16 speed
+-      range. For VC style input the loss seen is up to 0.2dB. See commit
+-      52cf4dca for further details.
+-
+-  - Quality:
+-      On the whole, quality is consistent with the Duclair release. Some
+-      tweaks:
+-
+-        Reduced blockiness in easy sections by applying a penalty to
+-        intra modes.
+-
+-        Improved quality of static sections (like slideshows) with
+-        two pass encoding.
+-
+-        Improved keyframe sizing with multiple temporal layers
+-
+-  - Bug Fixes:
+-      Corrected alt-ref contribution to frame rate for visible updates
+-      to the alt-ref buffer. This affected applications making manual
+-      usage of the frame reference flags, or temporal layers.
+-
+-      Additional constraints were added to disable multi-frame quality
+-      enhancement (MFQE) in sections of the frame where there is motion.
+-      (#392)
+-
+-      Fixed corruption issues when vpx_codec_enc_config_set() was called
+-      with spatial resampling enabled.
+-
+-      Fixed a decoder error introduced in Duclair where the segmentation
+-      map was not being reinitialized on keyframes (#378)
+-
+-
+-2012-01-27 v1.0.0 "Duclair"
+-  Our fourth named release, focused on performance and features related to
+-  real-time encoding. It also fixes a decoder crash bug introduced in
+-  v0.9.7, so all users of that release are encouraged to upgrade.
+-
+-  - Upgrading:
+-      This release is ABI incompatible with prior releases of libvpx, so the
+-      "major" version number has been bumped to 1. You must recompile your
+-      applications against the latest version of the libvpx headers. The
+-      API remains compatible, and this should not require code changes in most
+-      applications.
+-
+-  - Enhancements:
+-      This release introduces several substantial new features to the encoder,
+-      of particular interest to real time streaming applications.
+-
+-      Temporal scalability allows the encoder to produce a stream that can
+-      be decimated to different frame rates, with independent rate targetting
+-      for each substream.
+-
+-      Multiframe quality enhancement postprocessing can make visual quality
+-      more consistent in the presence of frames that are substantially
+-      different quality than the surrounding frames, as in the temporal
+-      scalability case and in some forced keyframe scenarios.
+-
+-      Multiple-resolution encoding support allows the encoding of the
+-      same content at different resolutions faster than encoding them
+-      separately.
+-
+-  - Speed:
+-      Optimization targets for this release included the decoder and the real-
+-      time modes of the encoder. Decoder speed on x86 has improved 10.5% with
+-      this release. Encoder improvements followed a curve where speeds 1-3
+-      improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved
+-      1.5% to 10.5%, respectively. "Best" mode speed is consistent with the
+-      Cayuga release.
+-
+-  - Quality:
+-      Encoder quality in the single stream case is consistent with the Cayuga
+-      release.
+-
+-  - Bug Fixes:
+-      This release fixes an OOB read decoder crash bug present in v0.9.7
+-      related to the clamping of motion vectors in SPLITMV blocks. This
+-      behavior could be triggered by corrupt input or by starting
+-      decoding from a P-frame.
+-
+-
+-2011-08-15 v0.9.7-p1 "Cayuga" patch 1
+-  This is an incremental bugfix release against Cayuga. All users of that
+-  release are strongly encouraged to upgrade.
+-
+-    - Fix potential OOB reads (cdae03a)
+-
+-          An unbounded out of bounds read was discovered when the
+-          decoder was requested to perform error concealment (new in
+-          Cayuga) given a frame with corrupt partition sizes.
+-
+-          A bounded out of bounds read was discovered affecting all
+-          versions of libvpx. Given an multipartition input frame that
+-          is truncated between the mode/mv partition and the first
+-          residiual paritition (in the block of partition offsets), up
+-          to 3 extra bytes could have been read from the source buffer.
+-          The code will not take any action regardless of the contents
+-          of these undefined bytes, as the truncated buffer is detected
+-          immediately following the read based on the calculated
+-          starting position of the coefficient partition.
+-
+-    - Fix potential error concealment crash when the very first frame
+-      is missing or corrupt (a609be5)
+-
+-    - Fix significant artifacts in error concealment (a4c2211, 99d870a)
+-
+-    - Revert 1-pass CBR rate control changes (e961317)
+-      Further testing showed this change produced undesirable visual
+-      artifacts, rolling back for now.
+-
+-
+-2011-08-02 v0.9.7 "Cayuga"
+-  Our third named release, focused on a faster, higher quality, encoder.
+-
+-  - Upgrading:
+-    This release is backwards compatible with Aylesbury (v0.9.5) and
+-    Bali (v0.9.6). Users of older releases should refer to the Upgrading
+-    notes in this document for that release.
+-
+-  - Enhancements:
+-          Stereo 3D format support for vpxenc
+-          Runtime detection of available processor cores.
+-          Allow specifying --end-usage by enum name
+-          vpxdec: test for frame corruption
+-          vpxenc: add quantizer histogram display
+-          vpxenc: add rate histogram display

+-          update configure for ios sdk 4.3
+-          Avoid text relocations in ARM vp8 decoder
+-          Generate a vpx.pc file for pkg-config.
+-          New ways of passing encoded data between encoder and decoder.
+-
+-  - Speed:
+-      This release includes across-the-board speed improvements to the
+-      encoder. On x86, these measure at approximately 11.5% in Best mode,
+-      21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6).
+-      On ARM Cortex A9 with Neon extensions, real-time encoding of video
+-      telephony content is 35% faster than Bali on single core and 48%
+-      faster on multi-core. On the NVidia Tegra2 platform, real time
+-      encoding is 40% faster than Bali.
+-
+-      Decoder speed was not a priority for this release, but improved
+-      approximately 8.4% on x86.
+-
+-          Reduce motion vector search on alt-ref frame.
+-          Encoder loopfilter running in its own thread

+-          Reduce unnecessary distortion computation
+-          Use diamond search to replace full search
+-          Preload reference area in sub-pixel motion search (real-time mode)
+-
+-  - Quality:
+-      This release focused primarily on one-pass use cases, including
+-      video conferencing. Low latency data rate control was significantly
+-      improved, improving streamability over bandwidth constrained links.
+-      Added support for error concealment, allowing frames to maintain
+-      visual quality in the presence of substantial packet loss.
+-
+-          Add rc_max_intra_bitrate_pct control
+-          Limit size of initial keyframe in one-pass.

+-
+-
+-2011-03-07 v0.9.6 "Bali"
+-  Our second named release, focused on a faster, higher quality, encoder.
+-
+-  - Upgrading:
+-    This release is backwards compatible with Aylesbury (v0.9.5). Users
+-    of older releases should refer to the Upgrading notes in this
+-    document for that release.

+-      query decoder to determine which reference frames were updated
+-      implemented error tracking in the decoder
+-      fix pipe support on windows
+-
+-  - Speed:
+-      Primary focus was on good quality mode, speed 0. Average improvement
+-      on x86 about 40%, up to 100% on user-generated content at that speed.
+-      Best quality mode speed improved 35%, and realtime speed 10-20%. This
+-      release also saw significant improvement in realtime encoding speed
+-      on ARM platforms.

+-
+-  - Quality:
+-      Best quality mode improved PSNR 6.3%, and SSIM 6.1%. This release
+-      also includes support for "activity masking," which greatly improves
+-      SSIM at the expense of PSNR. For now, this feature is available with
+-      the --tune=ssim option. Further experimentation in this area
+-      is ongoing. This release also introduces a new rate control mode
+-      called "CQ," which changes the allocation of bits within a clip to

+-
+-
+-2010-10-28 v0.9.5 "Aylesbury"
+-  Our first named release, focused on a faster decoder, and a better encoder.
+-
+-  - Upgrading:
+-    This release incorporates backwards-incompatible changes to the
+-    ivfenc and ivfdec tools. These tools are now called vpxenc and vpxdec.
+-
+-    vpxdec
+-      * the -q (quiet) option has been removed, and replaced with
+-        -v (verbose). the output is quiet by default. Use -v to see
+-        the version number of the binary.
+-
+-      * The default behavior is now to write output to a single file
+-        instead of individual frames. The -y option has been removed.
+-        Y4M output is the default.
+-
+-      * For raw I420/YV12 output instead of Y4M, the --i420 or --yv12
+-        options must be specified.
+-
+-          $ ivfdec -o OUTPUT INPUT
+-          $ vpxdec --i420 -o OUTPUT INPUT
+-
+-      * If an output file is not specified, the default is to write
+-        Y4M to stdout. This makes piping more natural.
+-
+-          $ ivfdec -y -o - INPUT | ...
+-          $ vpxdec INPUT | ...
+-
+-      * The output file has additional flexibility for formatting the
+-        filename. It supports escape characters for constructing a
+-        filename from the width, height, and sequence number. This
+-        replaces the -p option. To get the equivalent:
+-
+-          $ ivfdec -p frame INPUT
+-          $ vpxdec --i420 -o frame-%wx%h-%4.i420 INPUT
+-
+-    vpxenc
+-      * The output file must be specified with -o, rather than as the
+-        last argument.
+-
+-          $ ivfenc <options> INPUT OUTPUT
+-          $ vpxenc <options> -o OUTPUT INPUT
+-
+-      * The output defaults to webm. To get IVF output, use the --ivf
+-        option.
+-
+-          $ ivfenc <options> INPUT OUTPUT.ivf
+-          $ vpxenc <options> -o OUTPUT.ivf --ivf INPUT
+-
+-
+-  - Enhancements:
+-      ivfenc and ivfdec have been renamed to vpxenc, vpxdec.
+-      vpxdec supports .webm input
+-      vpxdec writes .y4m by default
