+ 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

+ files.
+
+ - Known Issues:
+ Frame Parallel decoding fails for segmented and non-420 files.
