-- Update to version 4.0

-  New features:

-  * Alpha Channel feature.

-  * Screen Content Coding (SCC).

-  * MV-HEVC feature.

-  Enhancements to existing features:

-  * Added support for the VMAF v3.x.

-  API changes

-  * Add command line parameter for Alpha Channel feature :option:`--alpha`.

-  * Add command line parameter for SCC feature :option:`--scc 1`.

-  * Add command line parameters for the MV-HEVC feature

-    :option:`--multiview-config "multiview_config.txt"`.

-  Optimizations

-  * Arm SIMD optimizations: Several time-consuming scalar C

-    functions now have SIMD implementations on Arm platforms.

-    Existing Arm SIMD implementations have also been optimized.

-    These optimizations result in up to 57% faster encoding

-    compared to release 3.6.

-  * Arm SIMD optimizations include use of Armv8.4 DotProd, Armv8.6

-    I8MM, and Armv9 SVE2 instruction set extensions. The following

-    algorithms now have optimized SIMD implementations: SAD, SSE,

-    DCT, SAO, convolution, quantization, intra_planar,

-    intraFilter, intrapred DC and IDCT16x16.

-  Bug fixes

-  * Fix for y4m pipe input broken.

-  * Fix SCC crash on multipass encode.

-  * Fix mcstf when :option:`--bframes` value was less than 5.

-  * Fix lowpass DCT for high bit depth.

-  * Fix issue in default code flow and memory leak.

-  * Fix scc crash on multipass encode.
