+The deprecated ``zarr.convenience`` sub-module has been removed.
+All functions are available in the top-level `zarr` namespace.
+
+The following deprecated methods have been removed:
+
+- ``AsyncArray.create`` - use `zarr.api.asynchronous.create_array` instead.
+- ``Array.create`` - use `zarr.create_array` instead.
+
+The ``codecs`` argument on the removed methods corresponds to a combination of the ``compressors`` and ``serializer`` arguments on their replacements,
+and the ``chunk_shape`` argument on the removed methods corresponds to the ``chunks`` argument on their replacements.
+
+The following deprecated properties have been removed:
+
+- ``AsyncArray.compressor`` - use ``AsyncArray.compressors[0]`` instead for Zarr format 2 arrays.
+- ``Array.compressor`` - use ``Array.compressors[0]`` instead for Zarr format 2 arrays.
+- ``AsyncGroup.create_dataset`` - use `AsyncGroup.create_array` instead
+- ``AsyncGroup.require_dataset`` - use `AsyncGroup.require_array` instead
+- ``Group.create_dataset`` - use `Group.create_array` instead
+- ``Group.require_dataset`` - use `Group.require_array` instead
+- ``Group.array`` - use `Group.create_array` instead
+
+The following deprecated functions have been removed:
+
+- ``zarr.api.asynchronous.tree`` - use `AsyncGroup.tree` instead
+- ``zarr.api.synchronous.tree`` - use `Group.tree` instead
+- ``zarr.tree`` - use `Group.tree` instead
+
+
+Setting ``zarr.storage.default_compressor`` is deprecated, use `zarr.config` to configure ``array.v2_default_compressor``
+e.g. ``zarr.config.set({'codecs.zstd':'numcodecs.Zstd', 'array.v2_default_compressor.numeric': 'zstd'})``
