+2019-01-31 v1.8.0 "Northern Shoveler Duck"
+ This release focused on encoding performance for realtime and VOD use cases.
+
+ - Upgrading:
+ This adds and improves several vp9 controls. Most are related to SVC:
+ VP9E_SET_SVC_FRAME_DROP_LAYER:
+ - Frame dropping in SVC.
+ VP9E_SET_SVC_INTER_LAYER_PRED:
+ - Inter-layer prediction in SVC.
+ VP9E_SET_SVC_GF_TEMPORAL_REF:
+ - Enable long term temporal reference in SVC.
+ VP9E_SET_SVC_REF_FRAME_CONFIG/VP9E_GET_SVC_REF_FRAME_CONFIG:
+ - Extend and improve this control for better flexibility in setting SVC
+ pattern dynamically.
+ VP9E_SET_POSTENCODE_DROP:
+ - Allow for post-encode frame dropping (applies to non-SVC too).
+ VP9E_SET_SVC_SPATIAL_LAYER_SYNC:
+ - Enable spatial layer sync frames.
+ VP9E_SET_SVC_LAYER_ID:
+ - Extend api to specify temporal id for each spatial layers.
+ VP9E_SET_ROI_MAP:
+ - Extend Region of Interest functionality to VP9.
+
+ - Enhancements:
+ 2 pass vp9 encoding has improved substantially. When using --auto-alt-ref=6,
+ we see approximately 8% for VBR and 10% for CQ. When using --auto-alt-ref=1,
+ the gains are approximately 4% for VBR and 5% for CQ.
+
+ For real-time encoding, speed 7 has improved by ~5-10%. Encodes targeted at
+ screen sharing have improved when the content changes significantly (slide
+ sharing) or scrolls. There is a new speed 9 setting for mobile devices which
+ is about 10-20% faster than speed 8.
+
+ - Bug fixes:
+ VP9 denoiser issue.
+ VP9 partition issue for 1080p.
+ VP9 rate control improvments.
+ Postprocessing Multi Frame Quality Enhancement (MFQE) issue.

+ encoding improvements.
+
+ - Upgrading:
+ This release is ABI incompatible due to new vp9 encoder features.
+
+ Frame parallel decoding for vp9 has been removed.
+
+ - Enhancements:
+ vp9 encoding supports additional threads with --row-mt. This can be greater
+ than the number of tiles.
+
+ Two new vp9 encoder options have been added:
+ --corpus-complexity
+ --tune-content=film
+
+ Additional tooling for respecting the vp9 "level" profiles has been added.

+2017-01-09 v1.6.1 "Long Tailed Duck"
+ This release improves upon the VP9 encoder and speeds up the encoding and
+ decoding processes.
+
+ - Upgrading:
+ This release is ABI compatible with 1.6.0.
+
+ - Enhancements:
+ Faster VP9 encoding and decoding.
+ High bit depth builds now provide similar speed for 8 bit encode and decode

+
+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
