+`cfe-dev <http://lists.cs.uiuc.edu/mailman/listinfo/cfe-dev>`_ or `openmp-dev

+In addition to OpenMP 3.1, several important elements of 4.0 version of the
+standard are supported as well:
+- ``omp simd``, ``omp for simd`` and ``omp parallel for simd`` pragmas
+- atomic constructs
+- ``proc_bind`` clause of ``omp parallel`` pragma
+- ``depend`` clause of ``omp task`` pragma (except for array sections)
