        * Use ``sys.implementation.name`` where appropriate for ``packaging.tags`` (`#193 <https://github.com/pypa/packaging/issues/193>`__)
        
        * Expand upon the API provded by ``packaging.tags``: ``interpreter_name()``, ``mac_platforms()``, ``compatible_tags()``, ``cpython_tags()``, ``generic_tags()`` (`#187 <https://github.com/pypa/packaging/issues/187>`__)
        
        * Officially support Python 3.8 (`#232 <https://github.com/pypa/packaging/issues/232>`__)

          This allows for using ``file:///absolute/path``, which was previously
          prevented due to the missing ``netloc``.

          ``Version`` and ``LegacyVersion`` (`#34 <https://github.com/pypa/packaging/issues/34>`__).
        
        * Add ``Version().is_devrelease`` and ``LegacyVersion().is_devrelease`` to
          make it easy to determine if a release is a development release.
        
        * Add ``utils.canonicalize_version`` to canonicalize version strings or
          ``Version`` instances (`#121 <https://github.com/pypa/packaging/issues/121>`__).

        16.6 - 2016-03-29
        ~~~~~~~~~~~~~~~~~
        
        * Add support for the deprecated, PEP 345 environment markers in addition to
          the newer markers.
        
        
        16.5 - 2016-02-26

        16.0 - 2016-01-19
        ~~~~~~~~~~~~~~~~~
        
        * Relicense so that packaging is available under *either* the Apache License,

        * Expose the specifier and version parts through properties on the
          ``Specifier`` classes.
        
        * Allow iterating over the ``SpecifierSet`` to get access to all of the
          ``Specifier`` instances.
        
        * Allow testing if a version is contained within a specifier via the ``in``
          operator.
        
        
        15.1 - 2015-04-13
        ~~~~~~~~~~~~~~~~~
        
        * Fix a logic error that was causing inconsistent answers about whether or not
          a pre-release was contained within a ``SpecifierSet`` or not.
        
        
        15.0 - 2015-01-02
        ~~~~~~~~~~~~~~~~~

          it easy to get the public version without any pre or post release markers.
        
        * Support the update to PEP 440 which removed the implied ``!=V.*`` when using
          either ``>V`` or ``<V`` and which instead special cased the handling of
          pre-releases, post-releases, and local versions when using ``>V`` or ``<V``.
        
        
        14.5 - 2014-12-17
        ~~~~~~~~~~~~~~~~~
        
        * Normalize release candidates as ``rc`` instead of ``c``.

        14.4 - 2014-12-15
        ~~~~~~~~~~~~~~~~~

        14.3 - 2014-11-19
        ~~~~~~~~~~~~~~~~~
        
        * **BACKWARDS INCOMPATIBLE** Refactor specifier support so that it can sanely
          handle legacy specifiers as well as PEP 440 specifiers.
        
        * **BACKWARDS INCOMPATIBLE** Move the specifier support out of
          ``packaging.version`` into ``packaging.specifiers``.
        
        
        14.2 - 2014-09-10
        ~~~~~~~~~~~~~~~~~
        
        * Add prerelease support to ``Specifier``.
        * Remove the ability to do ``item in Specifier()`` and replace it with
          ``Specifier().contains(item)`` in order to allow flags that signal if a
          prerelease should be accepted or not.
        * Add a method ``Specifier().filter()`` which will take an iterable and returns
          an iterable with items that do not match the specifier filtered out.
        
        
        14.1 - 2014-09-08
        ~~~~~~~~~~~~~~~~~
        
        * Allow ``LegacyVersion`` and ``Version`` to be sorted together.
        * Add ``packaging.version.parse()`` to enable easily parsing a version string
          as either a ``Version`` or a ``LegacyVersion`` depending on it's PEP 440
          validity.
        
        
        14.0 - 2014-09-05
