  ### Known Bugs
  -
  +- Encountered a compiler bug on IBM LC platforms when using the IBM XL C/C++
  + compiler. The issue is manifested in the `generate_aabbs_and_centroids` method
  + in the `spin_bvh.cpp` unit test. It seems that the compiler does not handle
  + the lambda capture of the arrays correctly which leads to a segfault. A
  + workaround for the IBM XL compiler is provided.

  ### Removed
  +- Removed `AXOM_ENABLE_CUB` option, since `CUB` is no londer used directly in
  + Axom code. Instead, we use `RAJA::stable_sort` with RAJA-v0.12.1 and fallback
  + to `std::stable_sort` with older versions of RAJA and when the code is built
  + without RAJA.
