The Mandarin Duck release has been finalized.

Since the initial release candidate, fixes have been merged to:

work around pic issue with gcc 6

Fix bug in use of zoom metric as part of arf breakout.

vp8dx.h: Add macro for skipping loop filter

Revert "Add frame width & height to frame pkt. Add test."

Fix crash invalid params for vp8 multres. Add test.

vpx_codec_enc_init_multi: fix segfault w/vp9

The release is available from the git repository[0] on the mandarinduck branch and the automatic v1.7.0 tarball[1].

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.
