-xxxx-yy-zz v1.4.0 "Changes for next release"
- vpxenc is changed to use VP9 by default.
- Encoder controls added for 1 pass SVC.
- Decoder control to toggle on/off loopfilter.
+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
+ for x86 targets. Other platforms and higher bit depth improvements are in
+ progress.
+
+ - Bug Fixes:
+ A variety of fuzzing issues.
+
+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
