Changelog
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.
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
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
Ensure that versions are normalized before comparison when used in a specifier with a less than (<) or greater than (>) operator.
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
Initial release.
