   To reproduce the behaviour in previous zarr-python versions when ``compressor=None`` was passed, pass ``compressor='auto'`` instead. (:issue:`3039`)
 - Fixed the typing of ``dimension_names`` arguments throughout so that it now accepts iterables that contain `None` alongside `str`. (:issue:`3045`)
 - Using various functions to open data with ``mode='a'`` no longer deletes existing data in the store. (:issue:`3062`)
+- Internally use `typesize` constructor parameter for :class:`numcodecs.blosc.Blosc` to improve compression ratios back to the v2-package levels. (:issue:`2962`)
+- Specifying the memory order of Zarr format 2 arrays using the ``order`` keyword argument has been fixed. (:issue:`2950`)
