+Added public API for Buffer ABCs and implementations.
+
+Use :mod:`zarr.buffer` to access buffer implementations, and
+:mod:`zarr.abc.buffer` for the interface to implement new buffer types.
+
+Users previously importing buffer from ``zarr.core.buffer`` should update their
+imports to use :mod:`zarr.buffer`. As a reminder, all of ``zarr.core`` is
+considered a private API that's not covered by zarr-python's versioning policy.

+When creating arrays without explicitly specifying a chunk size using `zarr.create` and other
+array creation routines, the chunk size will now set automatically instead of defaulting to the data shape.
+For large arrays this will result in smaller default chunk sizes.
+To retain previous behaviour, explicitly set the chunk shape to the data shape.
+
+This fix matches the existing chunking behaviour of
+`zarr.save_array` and `zarr.api.asynchronous.AsyncArray.create`.

+When `zarr.save` has an argument `path=some/path/` and multiple arrays in `args`, the path resulted in `some/path/some/path` due to using the `path`
+argument twice while building the array path. This is now fixed.
