 Fixes
 ~~~~~
-* Cleanup ``crc32c`` soft dependency.
+* Cleanups to the ``crc32c`` soft dependency.
+  Whereas in ``numcodecs`` 0.14.0 a runtime error was raised if
+  the ``CRC32C`` codec used without the ``crc32c`` installed,
+  the ``CRC32C`` codec is no longer defined at import time if
+  ``crc32c`` is not installed. This has been changed to match
+  the behaviour of other optional dependencies/codecs.
