+Kernel invocation (New Syntax)
+------------------------------
+
+Since the release 0.20.0 (Phoenix), we have introduced new kernel launch parameter
+syntax for specifying ``global_size`` and ``local_size`` that similar to ``SYCL``'s
+``range`` and ``ndrange`` classes. The ``global_size`` and ``local_size`` can now
+be specified with ``numba_dpex``'s ``Range`` and ``NdRange`` classes.
