Changelog
---------
20.4 - 2020-05-19
~~~~~~~~~~~~~~~~~
* Canonicalize version before comparing specifiers. (`#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.
20.3 - 2020-03-05
~~~~~~~~~~~~~~~~~
* Fix changelog for 20.2.
20.2 - 2020-03-05
~~~~~~~~~~~~~~~~~
* Fix a bug that caused a 32-bit OS that runs on a 64-bit ARM CPU (e.g.
ARM-v8,
aarch64), to report the wrong bitness.
20.1 - 2020-01-24
~~~~~~~~~~~~~~~~~~~
* Fix a bug caused by reuse of an exhausted iterator. (`#257
`__)
