+It is now possible to specify no compressor when creating a zarr format 2 array.
+This can be done by passing ``compressor=None`` to the various array creation routines.
+

+To reproduce the behaviour in previous zarr-python versions when ``compressor=None`` was passed, pass ``compressor='auto'`` instead.
