   - Compression Efficiency Improvements
     * Tuning mode AOM_TUNE_IQ improves image compression efficiency on
       the CLIC dataset by up to 12% for the same SSIMULACRA 2 score, up
       to 14% for the same DSSIM score, and up to 17% for the same

   - Perceptual Quality Improvements
     * Adjust temporal filter strength for better visual quality.

   - Speedup and Memory Optimizations
+    * Optimize the Arm Neon implementation of the loop filter functions

     * Add the CDEF optimization for RISC-V.
     * Help the compiler generate better vectorized code for variance
       calculation and warped motion in generic CPU builds.
     * Make several arrays const.
 
   - Other Improvements

+      CONFIG_AV1_HIGHBITDEPTH disabled.
     * Build: compile source files in parallel under MSVC.

     * Fix bug where metadata added with aom_img_add_metadata was lost
       when frame scaling was used.
