Here is an update to SVT-AV1 2.0.0.


## [2.0.0] - 2024-03-13

Major API updates
- Changed the API signaling the End Of Stream (EOS) with the last frame vs with an empty frame
- OPT_LD_LATENCY2 making the change above is kept in the code to help devs with integration
- Removed the 3-pass VBR mode which changed the calling mechanism of multi-pass VBR
- Moved to a new versioning scheme where the project major version will be updated everytime API/ABI is changed

Encoder
- Improve the tradeoffs for the random access mode across presets:
-   Speedup presets MR by ~100% and improved quality along with tradeoff improvements across the higher quality presets (!2179)
-   Improved the compression efficiency of presets M9-M13 by 1-4% (!2179)
-   Simplified VBR multi-pass to use 2 passes to allow integration with ffmpeg
- Continued adding ARM optimizations for functions with c_only equivalent
- Replaced the 3-pass VBR with a 2-pass VBR to ease the multi-pass integration with ffmpeg
- Memory savings of 20-35% for LP 8 mode in preset M6 and below and 1-5% in other modes / presets

Cleanup and bug fixes and documentation
- Various cleanups and functional bug fixes
- Update the documentation to reflect the rate control changes
