+- Update to version 3.4.0:
+  * This release includes compression efficiency and perceptual
+    quality improvements, speedup and memory optimizations, and
+    some new features. There are no ABI or API breaking changes in
+    this release.

+      quantization matrices in the distortion computation for RD
+      search. The default value is "psnr".
+    - New command line option "--auto-intra-tools-off=1" to make
+      all-intra encoding faster for high bit rate under
+      "--deltaq-mode=3" mode.

+      encoders. Supports CBR for both one spatial layer and SVC.
+    - New image format AOM_IMG_FMT_NV12 can be used as input to the
+      encoder. The presence of AOM_IMG_FMT_NV12 can be detected at
+      compile time by checking if the macro AOM_HAVE_IMG_FMT_NV12
+      is defined.
+    - New codec controls for the encoder:

+    - New aomenc options (not supported by the key-value API):
+      o --nv12
+  * Compression Efficiency Improvements:
+    - Correctly calculate SSE for high bitdepth in skip mode, 0.2%
+      to 0.6% coding gain.
+    - RTC at speed 9/10: BD-rate gain of ~4/5%
+    - RTC screen content coding: many improvements for real-time
+      screen at speed 10 (quality, speedup, and rate control), up
+      to high resolutions (1080p).
+    - RTC-SVC: fixes to make intra-only frames work for spatial
+      layers.
+    - RTC-SVC: quality improvements for temporal layers.
+    - AV1 RT: A new passive rate control strategy for screen
+      content, an average of 7.5% coding gain, with some clips of
+      20+%. The feature is turned off by default due to higher bit
+      rate variation.
+  * Perceptual Quality Improvements:
+    - RTC: Visual quality improvements for high speeds (9/10)
+    - Improvements in coding quality for all intra mode
+  * Speedup and Memory Optimizations:
+    - ~10% speedup in good quality mode encoding.
+    - ~7% heap memory reduction in good quality encoding mode for
+      speed 5 and 6.
+    - Ongoing improvements to intra-frame encoding performance on
+      Arm
+    - Faster encoding speed for "--deltaq-mode=3" mode.
+    - ~10% speedup for speed 5/6, ~15% speedup for speed 7/8, and
+      ~10% speedup for speed 9/10 in real time encoding mode
+    - ~20% heap memory reduction in still-picture encoding mode for
+      360p-720p resolutions with multiple threads
+    - ~13% speedup for speed 6 and ~12% speedup for speed 9 in
+      still-picture encoding mode.
+    - Optimizations to improve multi-thread efficiency for
+      still-picture encoding mode.
+  * Bug Fixes:
+    - b/204460717: README.md: replace master with main
+    - b/210677928: libaom disable_order is surprising for
+      max_reference_frames=3

+- Update to version 3.1.0 (bsc#1185843):
+  https://aomedia.googlesource.com/aom/+/refs/tags/v3.1.0
+
+  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
+    aom_codec_enc_config_default().
+
+    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
+  https://aomedia.googlesource.com/aom/+/refs/tags/v3.0.0

+for realtime mode, as well as some new APIs.
+

+      - AOMD_GET_STILL_PICTURE
+      - AOMD_GET_SB_SIZE
+      - AOMD_GET_SHOW_EXISTING_FRAME_FLAG
+      - AOMD_GET_S_FRAME_INFO
+
+    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
+    AV1E_SET_{COEFF/MODE}_COST_UPD_FREQ.
+
+    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.

+    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

+- 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.
