      • Optix and ODIN enhancement: Added specular reflections and refractions to the albedo, which can improve denoiser quality
      • Automatic selection of box filtering with OIDN and OptiX denoisers
    • LUT based tone mapping: Image tonemapper now supports LUT files based tone mapping.
    • Improved support for imagers shared by multiple drivers
    • Improved imagers refresh rate in IPR
    • Improved filter performance in progressive rendering
    • Added support for multiple parallel render sessions on CPU
    • Visible lights now transparent: allowing black parts of textured lights to be masked away
    • The EXR driver can now render AOVs as separate images
    •  The sss_setname feature that allows subsurface effects to spread between distinct objects is now supported in the randomwalk mode on CPU
    • GPU Enhancement:
      • Reduced VRAM use for polymeshes
      • Reduced VRAM use for GPU volumes:
      • Support for matte has been added to the GPU integrator

These were the major changes, but there are tons more including USD, API, bug fixes etc.
