Changelog --------- 20.9 - 2021-01-29 ~~~~~~~~~~~~~~~~~ * Run [isort](https://pypi.org/project/isort/) over the code base (:issue:`377`) * Add support for the ``macosx_10_*_universal2`` platform tags (:issue:`379`) * Introduce ``packaging.utils.parse_wheel_filename()`` and ``parse_sdist_filename()`` (:issue:`387` and :issue:`389`) 20.8 - 2020-12-11 ~~~~~~~~~~~~~~~~~ * Revert back to setuptools for compatibility purposes for some Linux distros (:issue:`363`) * Do not insert an underscore in wheel tags when the interpreter version number is more than 2 digits (:issue:`372`) 20.7 - 2020-11-28 ~~~~~~~~~~~~~~~~~ No unreleased changes. 20.6 - 2020-11-28 ~~~~~~~~~~~~~~~~~ .. note:: This release was subsequently yanked, and these changes were included in 20.7. * Fix flit configuration, to include LICENSE files (:issue:`357`) * Make `intel` a recognized CPU architecture for the `universal` macOS platform tag (:issue:`361`) * Add some missing type hints to `packaging.requirements` (issue:`350`) 20.5 - 2020-11-27 ~~~~~~~~~~~~~~~~~ * Officially support Python 3.9 (:issue:`343`) * Deprecate the ``LegacyVersion`` and ``LegacySpecifier`` classes (:issue:`321`) * Handle ``OSError`` on non-dynamic executables when attempting to resolve the glibc version string. 20.4 - 2020-05-19 ~~~~~~~~~~~~~~~~~ * Canonicalize version before comparing specifiers. (:issue:`282`) * Change type hint for ``canonicalize_name`` to return ``packaging.utils.NormalizedName``.

(:issue:`156`) * Correctly handle two-digit versions in ``python_version`` (:issue:`119`) 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. 18.0 - 2018-09-26 ~~~~~~~~~~~~~~~~~ * Improve error messages when invalid requirements are given. (:issue:`129`) 17.1 - 2017-02-28 ~~~~~~~~~~~~~~~~~ * Fix ``utils.canonicalize_version`` when supplying non PEP 440 versions. 17.0 - 2017-02-28 ~~~~~~~~~~~~~~~~~ * Drop support for python 2.6, 3.2, and 3.3. * Define minimal pyparsing version to 2.0.2 (:issue:`91`). * Add ``epoch``, ``release``, ``pre``, ``dev``, and ``post`` attributes to ``Version`` and ``LegacyVersion`` (:issue:`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 (:issue:`121`). 16.8 - 2016-10-29 ~~~~~~~~~~~~~~~~~ * Fix markers that utilize ``in`` so that they render correctly. * Fix an erroneous test on Python RC releases. 16.7 - 2016-04-23 ~~~~~~~~~~~~~~~~~ * Add support for the deprecated ``python_implementation`` marker which was an undocumented setuptools marker in addition to the newer markers. 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 ~~~~~~~~~~~~~~~~~ * Fix a regression in parsing requirements with whitespaces between the comma separators. 16.4 - 2016-02-22 ~~~~~~~~~~~~~~~~~ * 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. .. _`master`: https://github.com/pypa/packaging/
