x265 0.9 is a regularly scheduled bug fix release.  Many bugs have
been fixed since the 0.8 tag, primarily in rate control and 10bit
encodes.  A race hazard on POSIX systems was fixed, and several
non-determinism problems were resolved.

= API Changes =

* the stride of x265_picture is now in units of bytes, not pixels
* VUI configurables were moved into a param.vui sub-struct
* unimplemented VUI options removed
* bRepeatHeaders option added (inserts VPS+SPS+PPS each keyframe)
* fast-decode tune option added
* x265_encoder_headers() returns NAL byte count on success

= CLI Changes =

* --dither option to improve quality of pixel downshifts
* --cpuid replaced with x264 compatible --asm option
* --crf-max <float> added
* improved --help documentation, plus new online documentation
* **experimental** --interlaceMode <prog|tff|bff>
* **experimental** --weightb

= New Features =

* experimental support for interlaced content (field coding)
* experimental weightb support

We now have online documentation for this release
http://x265.readthedocs.org/en/0.9/
plus http://x265.readthedocs.org/en/default/ and
http://x265.readthedocs.org/en/stable for the two development
branches.

See the online manual for full documentation of CLI (and API) options

Our focus for the near future remains on visual quality and rate
control improvements.
