Bugs fixed

• Use importlib.util.find_spec() instead of the deprecated importlib.find_loader() function when setting up the package path at import-time. Patch by Matti Picus. (Github issue :issue:4764)

• Tuple multiplication was ignored in expressions such as [*(1,) * 2]. Patch by David Woods. (Github issue :issue:4864)

• Ensure that object buffers (e.g. ndarray[object, ndim=1]) containing NULL pointers are safe to use, returning None instead of the NULL pointer. Patch by Sebastian Berg. (Github issue :issue:4859)

• Using memoryview typed arguments in inner functions is now rejected as unsupported. Patch by David Woods. (Github issue :issue:4798)
