+2016-07-20 v1.6.0 "Khaki Campbell Duck"
+ This release improves upon the VP9 encoder and speeds up the encoding and
+ decoding processes.
+
+ - Upgrading:
+ This release is ABI incompatible with 1.5.0 due to a new 'color_range' enum
+ in vpx_image and some minor changes to the VP8_COMP structure.
+
+ The default key frame interval for VP9 has changed from 128 to 9999.
+
+ - Enhancement:
+ A core focus has been performance for low end Intel processors. SSSE3
+ instructions such as 'pshufb' have been avoided and instructions have been
+ reordered to better accommodate the more constrained pipelines.
+
+ As a result, devices based on Celeron processors have seen substantial
+ decoding improvements. From Indian Runner Duck to Javan Whistling Duck,
+ decoding speed improved between 10 and 30%. Between Javan Whistling Duck
+ and Khaki Campbell Duck, it improved another 10 to 15%.
+
+ While Celeron benefited most, Core-i5 also improved 5% and 10% between the
+ respective releases.
+
+ Realtime performance for WebRTC for both speed and quality has received a
+ lot of attention.
+
+ - Bug Fixes:
+ A number of fuzzing issues, found variously by Mozilla, Chromium and others,
+ have been fixed and we strongly recommend updating.
+
+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.
+
+ - Enhancements:
+ VP8 optimizations for MIPS dspr2
+ vpxenc: add -quiet option
+
