Just to be clear, the OpenMP 5.1 specification changes atomic by a considerable amount (especially it breaks capture into two sub-constructs (coming as a separate patch)) and AFAIK we are targeting OpenMP 5.0. So, do I still update it to the 5.1 standard (this will affect further implementation of atomic construct)?
