+2021-10-13 v3.2.0
+ This release includes compression efficiency and perceptual quality
+ improvements, speedup and memory optimizations, as well as some new
+ features.
+
+ - New Features
+ * Introduced speeds 7, 8, and 9 for all intra mode.
+ * Introduced speed 10 for real time mode.
+ * Introduced an API that allows external partition decisions.
+ * SVC: added support for compound prediction.
+ * SVC: added support for fixed SVC modes.
+
+ - Compression Efficiency Improvements
+ * Intra-mode search improvement.
+ * Improved real time (RT) mode BDrate savings by ~5% (RT speed 5)
+ and ~12% (RT speed 6). The improvement was measured on the video
+ conference set.
+ * Improved real time mode for nonrd path (speed 7, 8, 9): BDrate
+ gains of ~3-5%.
+ * Rate control and RD adjustments based on ML research in VP9.
+ Gains of ~0.5-1.0% for HD.
+
+ - Perceptual Quality Improvements
+ * Added a new mode --deltaq-mode=3 to improve perceptual quality
+ based on a differential contrast model for still images.
+ * Added a new mode –deltaq-mode=4 to improve perceptual quality
+ based on user rated cq_level data set for still images.
+ * Weighting of some intra mode and partition size choices to better
+ manage and retain texture.
+
+ - Speedup and Memory Optimizations
+ * Further improved 2-pass good quality encoder speed:
+ o Speed 2 speedup: 18%
+ o Speed 3 speedup: 22%
+ o Speed 4 speedup: 37%
+ o Speed 5 speedup: 30%
+ o Speed 6 speedup: 20%
+ * Optimized the real time encoder (measured on the video conference
+ set):
+ o RT speed 5 speedup: 110%
+ o RT speed 6 speedup: 77%
+
+ - Bug Fixes
+ * Issue 3069: Fix one-pass mode keyframe placement off-by-one error.
+ * Issue 3156: Fix a bug in av1_quantize_lp AVX2 optimization.
+
2021-09-29 v3.1.3
This release includes several bug fixes.
