• Added RTCError RTC_ERROR_LEVEL_ZERO_RAYTRACING_SUPPORT_MISSING which can indicate a GPU driver that is too old or not installed properly.
• Added the API function rtcGetDeviceLastErrorMessage to query additional information about the last RTCError returned by rtcGetDeviceError. This can be used in case device creation failed and a rtcErrorFunction could not be set up for this purpose.
• Added the API function rtcGetErrorString which returns a string representation of a given RTCError error code. This is purely meant for convenient error information reporting on the user application side.
• Performance improvements on GPU for the one level instancing case (RTC_MAX_INSTANCE_LEVEL_COUNT 1).
• Reduced the number of unneccessary GPU-CPU USM back-migrations which can increase build performance for scene with many instances on GPU.
• Started adding public CI tests for streamlining integration of external pull requests.
• Work-around for problem with unsigned Windows binaries.
