Here is an update to SVT-AV1 2.3.0.


## [2.3.0] - 2024-10-28

API updates
- Preset shift: M12/M13 mapped to M11, M7-M11 shifted one position down. API
  does not change, all presets from MR-M13 will still be accepted
- svt_av1_enc_get_packet API is now a blocking call for low-delay enforcing a
  picture in, picture out model
- --fast-decode range changed from 0-1 to 0-2 available on all presets
- Introducing a new definition of --lp being levels of parallelism with a new
  field in the config structure level_of_parallelism
- logical_processors will be deprecated in the 3.0 release

Encoder
- NEW FAST DECODE MODE - (!2280)
- New fast-decode (2) to allow for an average AV1 software cycle reduction of
  25-50% vs fast-decode 0 with a 1-3% BD-Rate loss across the presets
- Improved fast-decode (1) option to increase its AV1 software cycle reduction
  by ~10% while maintaining the same quality levels
- Improved --lp settings for high resolutions, with CRF gaining a ~4%
  improvement in speed and VBR gaining ~15% (!2323)
- Further Arm-based optimizations improving the efficiency of previously
  written Arm-neon implementations by an average of 30%. See below for more
  information on specific presets
- Address speed regressions for high resolutions first pass encode by tuning
  the threading parameters, with 1080p showing the biggest gains
- Enabled AVX512 by default in cmake allowing for ~2-4% speedup
- Enabled LTO by default if using a new enough compiler (!2288, !2305)
  - If LTO is a problem or causes one, it can be disabled by adding
    -DSVT_AV1_LTO=OFF to cmake to force it off.
  - Please report any issues that occur when using it.

Cleanup Build and bug fixes and documentation
- third_party: update safestringlib with applicable upstream changes
- Improved the unit test coverage for Arm-neon code
- Updated documentation

Arm Improvements

- Speed comparison was done against v2.2 on AWS Graviton4 instances with
  Clang 19.1.1
- `--lp 1` was used for all tests

## [2.2.0] - 2024-08-19

API updates
- No API changes on this release

Encoder
- Improve the tradeoffs for the random access mode across presets:
- Speedup of ~15% across presets M0 - M8 while maintaining similar quality
  levels (!2253)
- Improve the tradeoffs for the low-delay mode across presets (!2260)
- Increased temporal resolution setting to 6L for 4k resolutions by default
- Added Arm optimizations for functions with c_only equivalent yielding an
  average speedup of ~13% for 4k10bit

Cleanup Build and bug fixes and documentation
- Profile-guided-optimized helper build overhaul
- Major cleanup and fixing of Neon unit test suite
- Address stylecheck dependence on public repositories
