Latest ReSTIR GI Functionality

Hi
I’d like to explore the latest ReSTIR GI functionality but confused as to what branch I should download.
Is the latest functionality in the caustics branch?
https://github.com/NvRTX/UnrealEngine/tree/NvRTX_Caustics-5.4
or should I download the default 5.4 branch?
https://github.com/NvRTX/UnrealEngine/tree/nvrtx-5.4

hey,
Caustics branch [NvRTX_Caustics-5.4] is the latest tech.
But you may encounter a crash during activation of caustics.
