features as well as additional assembly optimizations for Main12, intra
prediction and SAO. Recently added features lookahead-slices, limit-refs
and limit-modes have been enabled by default in the supported presets.

========================================== New Features
==============================================

   - Quant offsets: This feature allows block level quantization offsets
     to be specified for every frame. An API-only feature.
   - --intra-refresh: Keyframes can be replaced by a moving column of
     intra blocks in non-keyframes.
   - --limit-modes: Intelligently restricts mode analysis.
   - --max-luma and --min-luma for luma clipping, optional for HDR
     use-cases
   - Emergency denoising is now enabled by default in very low bitrate,
     VBV encodes

=========================================== API Changes
==============================================

   - x265_frame_stats returns many additional fields: maxCLL, maxFALL,
     residual energy, scenecut  and latency logging
   - --qpfile now supports frametype 'K"
   - x265 now allows CRF ratecontrol in pass N (N greater than or equal
     to 2)
   - Chroma subsampling format YUV 4:0:0 is now fully supported and
     tested

====================================== Presets and Performance
==========================================

   - Recently added features lookahead-slices, limit-modes, limit-refs
     have been enabled by default for applicable presets.
   - The default psy-rd strength has been increased to 2.0
   - Multi-socket machines now use a single pool of threads that can
     work cross-socket.
