===) was not correctly allowing pre-releases when it was being used. - Expose the specifier and version parts through properties on the
Specifierclasses. - Allow iterating over the
SpecifierSetto get access to all of theSpecifierinstances. - Allow testing if a version is contained within a specifier via the

a pre-release was contained within a
SpecifierSetor not.

Version().base_versionandLegacyVersion().base_versionto 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>Vor<Vand which instead special cased the handling of pre-releases, post-releases, and local versions when using>Vor<V.
- Normalize release candidates as
rcinstead ofc. - Expose the
VERSION_PATTERNconstant, a regular expression matching a valid version.
- Ensure that versions are normalized before comparison when used in a
specifier with a less than (
<) or greater than (>) operator.
- 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.versionintopackaging.specifiers.

Specifier. - Remove the ability to do
item in Specifier()and replace it withSpecifier().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.
- Allow
LegacyVersionandVersionto be sorted together. - Add
packaging.version.parse()to enable easily parsing a version string as either aVersionor aLegacyVersiondepending on it's PEP 440 validity.
- Initial release.
