20.4:
Canonicalize version before comparing specifiers.
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:
Fix changelog for 20.2.
20.2:
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:
Fix a bug caused by reuse of an exhausted iterator.
20.0:
Add type hints
Add proper trove classifiers for PyPy support
Scale back depending on ctypes for manylinux support detection
Use sys.implementation.name where appropriate for packaging.tags
Expand upon the API provded by packaging.tags: interpreter_name(), mac_platforms(), compatible_tags(), cpython_tags(), generic_tags()
Officially support Python 3.8
Add major, minor, and micro aliases to packaging.version.Version
Properly mark packaging has being fully typed by adding a py.typed file
