x265 version 2.2 has been released. This release contains new algorithms to
limit the search of optimal transform units, a new motion search method,
and optimizations to the bitstream. With this release, x265 also supports
POWERPC platforms, with key functions optimized by using ALTIVEC kernels.
The latest version can be downloaded from here

New motion search method SEA (Successive Elimination Algorithm)
supported now as –me 4
Bit-stream optimizations to improve fields in PPS and SPS for bit-rate
savings through –[no-]opt-qp-pps, –[no-]opt-ref-list-length-pps, and
–[no-]multi-pass-opt-rps.
Enabled using VBV constraints when encoding without WPP.
All param options dumped in SEI packet in bitstream when info selected.
x265 now supports POWERPC-based systems. Several key functions also have
optimized ALTIVEC kernels.

New option –scenecut-bias to enable controlling bias to mark scene-cuts
via cli.
Support mono and mono16 color spaces for y4m input.
–min-cu-size of 64 no-longer supported for reasons of visual quality
(was crashing earlier anyways.)
API for CSV now expects version string for better integration of x265
into other applications.
–log2-max-poc-lsb‘s range limited according to HEVC spec.
Restrict MVs to within legal boundaries when encoding.
