+Fix a bug in ``create_array`` caused by iterating over chunk-aligned regions instead of
+shard-aligned regions when writing data. Additionally, the behavior of ``nchunks_initialized``
+has been adjusted. This function consistently reports the number of chunks present in stored objects,
+even when the array uses the sharding codec.

+Added `zarr.errors.ArrayNotFoundError`, which is raised when attempting to open a zarr array that does not exist, and `zarr.errors.NodeNotFoundError`, which is raised when failing to open an array or a group in a context where either an array or a group was expected.

@@ -0,0 +1 @@
+Raise a Zarr-specific error class when a codec can't be found by name when deserializing the given codecs. This avoids hiding this error behind a "not part of a zarr hierarchy" warning.
