[Version 2024.02.1] - Release date 2024-04-19

Changed

Updated to BLT v0.6.2, Umpire v2024.02.1, and RAJA v2024.02.1

[Version 2024.02.0] - Release date 2024-03-04

Added

Support for APUs with a single memory space. To use, configure with -DCHAI_DISABLE_RM=ON -DCHAI_GPU_THIN_ALLOCATE=ON.

Changed

Moved installed CMake targets from share/chai/cmake to lib/cmake/chai to be consistent with other libraries in the RAJA Portability Suite
Improved dependency handling during the build of CHAI and when it is imported into another library/application
Removed ArrayManager::enableDeviceSynchronization and ArrayManager::disableDeviceSynchronization. Instead, use the environment variables for device synchronization after all kernels (e.g. CUDA_LAUNCH_BLOCKING or HIP_LAUNCH_BLOCKING)

Fixed

Use free instead of realloc when the size is 0 (fixes a warning from valgrind)
