+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
+      o Add aom_quantize_b_avx2() 1.4x to 1.7x faster than aom_quantize_b_avx()
+      o Add aom_quantize_b_32x32_avx2() 1.4x to 2.3x faster than
+        aom_quantize_b_32x32_avx()
+      o Add aom_quantize_b_64x64_avx2() 2.0x to 2.4x faster than
+        aom_quantize_b_64x64_ssse3()
+      o Add aom_highbd_quantize_b_32x32_avx2() 9.0x to 10.5x faster than
+        aom_highbd_quantize_b_32x32_c()
+      o Add aom_highbd_quantize_b_64x64_avx2() 7.3x to 9.7x faster than
+        aom_highbd_quantize_b_64x64_c()
+      o Improve aom_highbd_quantize_b_avx2() 1.07x to 1.20x faster
+      o Improve av1_quantize_fp_avx2() 1.13x to 1.49x faster
+      o Improve av1_quantize_fp_32x32_avx2() 1.07x to 1.54x faster
+      o Improve av1_quantize_fp_64x64_avx2()  1.03x to 1.25x faster
+      o Improve av1_quantize_lp_avx2() 1.07x to 1.16x faster
+
