2017-01-04 v1.7.0 "Mandarin Duck"
This release focused on high bit depth performance (10/12 bit) and vp9
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.
- Bug fixes:
A variety of fuzzing issues.
vp8 threading fix for ARM.
Codec control VP9_SET_SKIP_LOOP_FILTER fixed.
Reject invalid multi resolution configurations.
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.

CODE STYLE:
The coding style used by this project is enforced with clang-format using the
configuration contained in the .clang-format file in the root of the
repository.
Before pushing changes for review you can format your code with:
# Apply clang-format to modified .c, .h and .cc files
$ clang-format -i --style=file \
$(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
Check the .clang-format file for the version used to generate it if there is
any difference between your local formatting and the review system.
