  • Fix a regression in parsing requirements like foo (==4).

16.3 - 2016-02-21

  • Fix a bug where packaging.requirements:Requirement was overly strict when matching legacy requirements.

16.2 - 2016-02-09

  • Add a function that implements the name canonicalization from PEP 503.

16.1 - 2016-02-07

  • Implement requirement specifiers from PEP 508.

16.0 - 2016-01-19

  • Relicense so that packaging is available under either the Apache License, Version 2.0 or a 2 Clause BSD license.
  • Support installation of packaging when only distutils is available.
  • Fix == comparison when there is a prefix and a local version in play. (:issue:`41`).
  • Implement environment markers from PEP 508.

15.3 - 2015-08-01

  • Normalize post-release spellings for rev/r prefixes. :issue:`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.
  • 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.
