 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.
