+- update to 20.4:
+  * Canonicalize version before comparing specifiers. (:issue:`282`)
+  * Change type hint for ``canonicalize_name`` to return
+  ``packaging.utils.NormalizedName``.
+  This enables the use of static typing tools (like mypy) to detect mixing of
+  normalized and un-normalized names.
