+For Zarr format 2, allow fixed-length string arrays to be created without automatically inserting a
+``Vlen-UT8`` codec in the array of filters. Fixed-length string arrays do not need this codec. This
+change fixes a regression where fixed-length string arrays created with Zarr Python 3 could not be read with Zarr Python 2.18.

+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`.
