 Enhancements
 ~~~~~~~~~~~~
 
-* Add support for the Linux aarch64 architecture, and bump the minimum
-macOS deployment target for x86_64 to 10.13.
+* Add ``typesize`` argument to ``Blosc`` to allow for buffers that are passed to ``encode``
+  use that information.  zarr v3 currently has its Blosc codec as bytes-to-bytes but does retain
+  the size information so using it here allows for massive compression ratio gains.
