 ### Known issues
 
-* In `hipsparseSpSM_solve()`, we currently pass the external buffer as a parameter. This does not match the NVIDIA CUDA cuSPARSE API and this extra external buffer parameter will be removed in a future release. For now this extra parameter can be ignored and nullptr passed as it is unused internally by `hipsparseSpSM_solve()`.
