Packaging

~~~~~~~~~~~~~~~~~

* Explicitly declare support for Python 3.11 (:issue:`587`)
* Remove support for Python 3.6 (:issue:`500`)
* Remove ``LegacySpecifier`` and ``LegacyVersion`` (:issue:`407`)
* Add ``__hash__`` and ``__eq__`` to ``Requirement`` (:issue:`499`)
* Add a ``cpNNN-none-any`` tag (:issue:`541`)
* Adhere to :pep:`685` when evaluating markers with extras (:issue:`545`)
* Allow accepting locally installed prereleases with ``SpecifierSet`` (:issue:`515`)
* Allow pre-release versions in marker evaluation (:issue:`523`)
* Correctly parse ELF for musllinux on Big Endian (:issue:`538`)
* Document ``packaging.utils.NormalizedName`` (:issue:`565`)
* Document exceptions raised by functions in ``packaging.utils`` (:issue:`544`)
* Fix compatible version specifier incorrectly strip trailing ``0`` (:issue:`493`)
* Fix macOS platform tags with old macOS SDK (:issue:`513`)
* Forbid prefix version matching on pre-release/post-release segments (:issue:`563`)
* Normalize specifier version for prefix matching (:issue:`561`)
* Improve documentation for ``packaging.specifiers`` and ``packaging.version``. (:issue:`572`)

Evaluating markers like ``"extra == 'xyz'"`` without passing any extra in the
``environment`` will no longer raise an exception (:issue:`550`)
* Remove dependency on ``pyparsing``, by replacing it with a hand-written parser.
This package now has no runtime dependencies (:issue:`468`)

to use ``Iterator`` instead of ``Iterable`` (:issue:`584`)

* Drop support for Python 2.7, Python 3.4 and Python 3.5.
* Replace distutils usage with sysconfig (:issue:`396`)
* Add support for zip files in ``parse_sdist_filename`` (:issue:`429`)
* Use cached ``_hash`` attribute to short-circuit tag equality comparisons (:issue:`417`)
