19.0 - 2019-01-20
Fix string representation of PEP 508 direct URL requirements with markers.
Better handling of file URLs
This allows for using file:///absolute/path, which was previously prevented due to the missing netloc.
This allows for all file URLs that urlunparse turns back into the original URL to be valid.

- Define minimal pyparsing version to 2.0.2 (#91).
- Add epoch, release, pre, dev, and post attributes to Version and LegacyVersion (#34).

- Normalize post-release spellings for rev/r prefixes. #35
15.2 - 2015-05-13
- Fix an error where the arbitary specifier (===) was not correctly allowing pre-releases when it was being used.
- Expose the specifier and version parts through properties on the Specifier classes.

- 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
- Add Version().is_postrelease and LegacyVersion().is_postrelease to make it easy to determine if a release is a post release.
- Add Version().base_version and LegacyVersion().base_version to make 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.
- Expose the VERSION_PATTERN constant, a regular expression matching a valid version.
14.4 - 2014-12-15

- 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
- Initial release.
