 2022-08-31 v3.5.0
 
   This release is ABI compatible with the last one, including speedup and memory
   optimizations, and new APIs and features.
   - New Features
     * Support for frame parallel encode for larger number of threads. --fp-mt
       flag is available for all build configurations.
     * New codec control AV1E_GET_NUM_OPERATING_POINTS
   - Speedup and Memory Optimizations
     * Speed-up multithreaded encoding for good quality mode for larger number of
       threads through frame parallel encoding:
       o 30-34% encode time reduction for 1080p, 16 threads, 1x1 tile
         configuration (tile_rows x tile_columns)
       o 18-28% encode time reduction for 1080p, 16 threads, 2x4 tile
         configuration
       o 18-20% encode time reduction for 2160p, 32 threads, 2x4 tile
         configuration
     * 16-20% speed-up for speed=6 to 8 in still-picture encoding mode
     * 5-6% heap memory reduction for speed=6 to 10 in real-time encoding mode
     * Improvements to the speed for speed=7, 8 in real-time encoding mode
     * Improvements to the speed for speed=9, 10 in real-time screen encoding
       mode
     * Optimizations to improve multi-thread efficiency in real-time encoding
       mode
     * 10-15% speed up for SVC with temporal layers
     * SIMD optimizations:
       o Improve av1_quantize_fp_32x32_neon() 1.05x to 1.24x faster
       o Add aom_highbd_quantize_b{,_32x32,_64x64}_adaptive_neon() 3.15x to 5.6x
         faster than "C"
       o Improve av1_quantize_fp_64x64_neon() 1.17x to 1.66x faster
