RADL pictures, moving from YASM to NASM assembler and reduced x265 build
time by more than 50%. The tarball of this release can be downloaded from

========================

Version 2.7
=========

New features
-----------------
1. :option:`--gop-lookahead` can be used to extend the gop boundary(set by
`--keyint`). The GOP will be extended, if a scene-cut frame is found within
this many number of frames.
2. Support for RADL pictures added in x265.
   :option:`--radl` can be used to decide number of RADL pictures preceding
the IDR picture.

Encoder enhancements
-------------------------------
1. Moved from YASM to NASM assembler. Supports NASM assembler version 2.13
and greater.
2. Enable analysis save and load in a single run. Introduces two new cli
options `--analysis-save <filename>` and `--analysis-load <filename>`.
3. Comply to HDR10+ LLC specification.
4. Reduced x265 build time by more than 50% by re-factoring ipfilter.asm.

Bug fixes
------------
1. Fixed inconsistent output issue in deblock filter and --const-vbv.
2. Fixed Mac OS build warnings.
3. Fixed inconsistency in pass-2 when weightp and cutree are enabled.
4. Fixed deadlock issue due to dropping of BREF frames, while forcing slice
types through qp file.
