 +yyyy-mm-dd next version
 +  This release is ABI compatible with the last release.
 +
 +  This release includes significant compression efficiency and perceptual
 +  quality improvements for layered image encoding, in addition to bug
 +  fixes.
 +
 +  - New Features
 +    * Tuning modes AOM_TUNE_IQ and AOM_TUNE_SSIMULACRA2 now work with
 +      inter-frame encoding modes (good-quality and realtime), enabling
 +      efficient layered image encoding.
 +    * Variance Boost (deltaq-mode 6) support has been extended to
 +      include good-quality and realtime modes.
 +    * New value 2 for use_fixed_qp_offsets: disallow the application of
 +      per-frame QP offsets, enabling full control of each frame's QP, by
 +      adjusting rc_cfg.cq_level between each encoded frame.
 +
 +  - Compression Efficiency Improvements
 +    * When encoding 2-layered images with AOM_TUNE_IQ vs. AOM_TUNE_SSIM:
 +      - Good-quality mode: up to 15% gains at similar SSIMULACRA 2 scores.
 +      - Realtime mode: up to 30% gains at similar SSIMULACRA 2 scores.
 +    * Enable screen detection mode 2 (anti-aliased text and graphics aware) in
 +      all-intra mode.
 +    * Some minor quantization matrix formula and delta chroma q tweaks for the
 +      AOM_TUNE_SSIMULACRA2 tuning mode, with up to 0.2% SSIMULACRA 2 score
 +      efficiency gains.
 +
 +  - Perceptual Quality Improvements
 +    * AOM_TUNE_IQ improves the visual quality of layered image encoding
 +      compared to AOM_TUNE_SSIM.
 +    * Adaptive sharpness: tweak loop filter sharpness threshold to improve
 +      visual quality at QPs 29 and 30.
 +
 +  - Speedups
 +    * Make Adaptive CDEF more decoder friendly by limiting CDEF application to
 +      only regions where high filter strengths are needed.
 +
 +  - Bug Fixes
 +    * Commit 4cc0867f: fix multithreading crashes when loop restoration
 +      filtering is used by the encoder.
 +    * Commit 74aaa1ef: fix AOM_SCALING_MODE crashes when compound mask
 +      prediction modes are used by the encoder.
