x265 version 2.0 has been released. This release supports many new features as well as support for ARM assembly optimizations for most basic pixel and ME operations, as well as SAO cleanups and a fully tested reconfigure functionality.
Full documentation is available at http://x265.readthedocs.org/en/stable/
==================== New Features====================
uhd-bd: Enforce Ultra-HD Blu-ray Disc parameters (overrides any other settings)
rskip: Enables skipping recursion to analyze lower CU sizes using heuristics at different rd-levels. Provides good visual quality gains at the highest quality presets.
rc-grain: Enables a new rate control mode specifically for grainy content. Strictly prevents QP oscillations within and between frames to avoid grain fluctuations.
tune grain: A fully refactored and improved option to encode film grain content including QP control as well as analysis options.
asm: ARM assembly is now enabled by default, native or cross compiled builds supported on armv6 and later systems.
============ API and Key Behavior Changes ==============
x265_rc_stats added to x265_picture, containing all RC decision points for that frame
PTL: high tier is now allowed by default, chosen only if necessary
multi-pass: First pass now uses slow-firstpass by default, enabling better RC decisions in future passes
pools: fix behaviour on multi-socketed Windows systems, provide more flexibility in determining thread and pool counts
ABR: improve bits allocation in the first few frames, abr reset, vbv and cutree improved
====================== Misc =========================
An SSIM calculation bug was corrected

Xvid style encoder were every preset is pleasing for the eye in contrast to x264 were only Placebo prevents eye cancer but there is one huge problem as it looks artificial as there is a film over it (others called it washed out)

I have been using the stable version non stop with excellent results. Far more superior than x264 and this is only the beginning. A big thank you to the developers for this amazing encoder.

Can't believe I'm the first to review such a great program here. The compression of this encoder is unreal and getting cleaner and faster as time goes on. By my own tests, 1.7 is about 33% faster than 1.6 which is amazing and hope further optimizations happen. x264 had to start somewhere and x265 will be no different.

Over the past month I have been encoding with it on high bitrate x264 files that I don't care to keep at their current file size, so I encode them with this with avisynth to retain most of the detail at a fraction of the size. I'm also doing this just to get a handle on this new HEVC beast.

All I need now is a HEVC TV Player...
