  - Update to version 3.2.0:
    * 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
      + 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:
      . Speed 2 speedup: 18%
      . Speed 3 speedup: 22%
      . Speed 4 speedup: 37%
      . Speed 5 speedup: 30%
      . Speed 6 speedup: 20%
      + Optimized the real time encoder (measured on the video
      conference set):
      . RT speed 5 speedup: 110%
      . RT speed 6 speedup: 77%
    * Bug Fixes
      + Issue 3069: Fix one-pass mode keyframe placement off-by-one
      + Issue 3156: Fix a bug in av1_quantize_lp AVX2 optimization.

  - Update to version 3.1.0 (bsc#1185843):
    This release adds an "all intra" mode to the encoder, which significantly
    speeds up the encoding of AVIF still images at speed 6.
    - Upgrading:
      All intra mode for encoding AVIF still images and AV1 all intra videos:
      AOM_USAGE_ALL_INTRA (2) can be passed as the 'usage' argument to
      New encoder control IDs added:
    - AV1E_SET_ENABLE_DIAGONAL_INTRA: Enable diagonal (D45 to D203) intra
      prediction modes (0: false, 1: true (default)). Also available as
      "enable-diagonal-intra" for the aom_codec_set_option() function.
      New aom_tune_metric enum value: AOM_TUNE_BUTTERAUGLI. The new aomenc option
    - -tune=butteraugli was added to optimize the encoder’s perceptual quality by
      optimizing the Butteraugli metric. Install libjxl (JPEG XL) and then pass
    - DCONFIG_TUNE_BUTTERAUGLI=1 to the cmake command to enable it.
  - Includes 3.0
    This release includes compression efficiency improvement, speed improvement
    for realtime mode, as well as some new APIs.
    - Upgrading:
      Support for PSNR calculation based on stream bit-depth.
      New encoder control IDs added:
      New decoder control IDs added:
      New aom_tune_content enum value: AOM_CONTENT_FILM
      New aom_tune_metric enum value: AOM_TUNE_VMAF_NEG_MAX_GAIN
      Coefficient and mode update can be turned off via
      New key & value API added, available with aom_codec_set_option() function.
      Scaling API expanded to include 1/4, 3/4 and 1/8.
    - Enhancements:
      Better multithreading performance with realtime mode.
      New speed 9 setting for faster realtime encoding.
      Smaller binary size with low bitdepth and realtime only build.
      Temporal denoiser and its optimizations on x86 and Neon.
      Optimizations for scaling.
      Faster encoding with speed settings 2 to 6 for good encoding mode.
      Improved documentation throughout the library, with function level
      documentation, tree view and support for the dot tool.
    - Bug fixes:
      Aside from those mentioned in v2.0.1 and v2.0.2, this release includes the
      following bug fixes:
      Issue 2940: Segfault when encoding with --use-16bit-internal and --limit > 1
      Issue 2941: Decoder mismatch with --rt --bit-depth=10 and --cpu-used=8
      Issue 2895: mingw-w64 i686 gcc fails to build
      Issue 2874: Separate ssse3 functions from sse2 file.
* Mon Mar 01 2021
  - Update to version 2.0.2:
    * Prepare for the libaom v2.0.2 release
    * Call av1_setup_frame_size() when dropping a frame
    * Avoid memset in filter_intra_predictor module
    * Fix a typo bug in apply_temporal_filter_planewise
    * Modify the assertion in temporal filter intrinsics
    * Fix unit test ThreadTestLarge.EncoderResultTest/49
    * Add -Wimplicit-function-declaration as C flag only
    * Update CHANGELOG for libaom v2.0.1
    * Set allow_screen_content_tools to 0 in rt mode
    * chroma_check: don't access UV planes if monochrome
* Tue May 19 2020
  - Update to version 2.0.0 "Applejack":
    This is the first official release of libaom. It has real-time
    mode and SVC support, as well as substantial documentation
    improvement and clean-ups.
    Important changes:
    * Decouple library version and so version.
    * Move functions into a header file
    * Remove av1_ prefix from static functions
    * Remove aom_ prefix from static functions
    * Remove aom_ prefix for static functions
    * Remove av1_ prefix for a static function
  - Drop libaom-0002-link-threading-lib-with-shared-library.patch and
* Tue Jul 31 2018
  - Enable CONFIG_LOWBITDEPTH. Makes 8-bit decoding faster. The only
    reason this confusingly-named option is not enabled by default
    is that its behavior might not match the 16-bit reference code
    path, and that hardware vendors want to be able to validate
    their designs against it. No actual mismatches have been found.
* Mon Jul 30 2018
  - Pass conditional AOM_TARGET_CPU to cmake, fix build for arm and
    ppc, as well as optimize target cpu for other arches.
* Fri Jul 27 2018
  - Init, v1.0.0
