CHANGES IN VERSION 0.99.1 (2023 Nov)

• the R global option variable 'HIBAG_GPU_INIT_TRAIN_PREC' can be set before loading the HIBAG.gpu package via e.g., options(HIBAG_GPU_INIT_TRAIN_PREC="half"). It should be NULL (unset), 'auto', 'half', 'mixed', 'single' or 'double'. It can be used without calling hlaGPU_Init(,train_prec="") to reset the training precision.
• fix the GPU memory leaks

CHANGES IN VERSION 0.99.0 (2021 Oct)

• remove the dependency of the OpenCL R package
• reimplement the HIBAG GPU algorithm for speed-up
• new implementation using half and mixed precisions
• a new function hlaAttrBagging_MultiGPU() to leverage multiple GPU devices
