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. -- cgit v1.2.3
