Changelog

26.0

~~~~~~~~~~~~~~~~~

Features:

* PEP 751: support pylock (:pull:`900`)
* PEP 794: import name metadata (:pull:`948`)
* Support for writing metadata to a file (:pull:`846`)
* Support ``__replace__`` on Version (:pull:`1003`)

Behavior adaptations:

* Support arbitrary equality on arbitrary strings for ``Specifier`` and ``SpecifierSet``'s ``filter`` and ``contains`` method. (:pull:`954`)
* Only try to parse as ``Version`` on certain marker keys, return ``False`` on unequal ordered comparisons (:pull:`939`)

Fixes:

* Update ``_hash`` when unpickling ``Tag()`` (:pull:`860`)
* Correct comment and simplify implicit prerelease handling in ``Specifier.prereleases`` (:pull:`896`)

* Correct regex for metadata ``'name'`` format (:pull:`925`)
* Improve the message around expecting a semicolon (:pull:`833`)
* Support nested parens in license expressions (:pull:`931`)
* Add space before at symbol in ``Requirements`` string (:pull:`953`)
* A root logger use found, use a ``packaging`` logger instead (:pull:`965`)
* Better support for subclassing ``Marker`` and ``Requirement`` (:pull:`1022`)
* Normalize all extras, not just if it comes first (:pull:`1024`)
* Don't produce a broken repr if ``Marker`` fails to construct (:pull:`1033`)

Performance:

* Avoid recompiling regexes in the tokenizer for a 3x speedup (:pull:`1019`)
* Improve performance in ``_manylinux.py`` (:pull:`869`)

* Minor ``Version`` regex cleanup (:pull:`990`)
* Faster regex on Python 3.11.5+ for ``Version`` (:pull:`988`, :pull:`1055`)
* Lazily calculate ``_key`` in ``Version`` (:pull:`989`, :pull:`1048`)
* Faster ``canonicalize_version`` (:pull:`993`)
* Use ``re.fullmatch`` in a couple more places (:pull:`992`, :pull:`1029`)
* Use ``map`` instead of generator (:pull:`996`)
* Deprecate ``._version`` (``_Version``, a ``NamedTuple``) (:pull:`995`, :pull:`1062`)
* Avoid duplicate ``Version`` creation in ``canonicalize_version`` (:pull:`994`)

* Pull ``set`` construction out of function (:pull:`1012`)
* Letter normalization dict for prereleases and the like (:pull:`1014`)
* Use ``str.partition`` in ``_parse_project_urls`` (:pull:`1013`)
* Avoid normalizing extras again when comparing (:pull:`1028`)
* Speed up ``Version.__str__`` by about 10% (:pull:`997`)
* Much faster ``canonicalize_name`` by avoiding a regex (:pull:`1030`, :pull:`1047`, :pull:`1064`)
* Faster zero stripping (:pull:`1058`)

* Simpler else instead of assert in a check (:pull:`1027`, :pull:`1031`)
* Synchronize documentation and code for markers (:pull:`1008`)
* Use the GitHub Actions slim runner for the all pass check (:pull:`1021`)
* Use ``actionlint`` to check CI workflows (:pull:`1052`)
* Use Trusted Publishing (:pull:`893`, :pull:`1043`, :pull:`1045`, :pull:`1051`)

Since the final release candidate: Faster ``canonicalize_name``, especially on
Python 3.12 and 3.13, where performance regressed previously (:pull:`1064`),
and reintroduce (deprecated) support for ``Version._.version`` (:pull:`1062`).

26.0rc3

~~~~~~~~~~~~~~~~~~~~

Third release candidate for 26.0. Avoid bug in CPython 3.11.0-3.11.4 and older
PyPy 3.11 (:pull:`1055`).

26.0rc2

~~~~~~~~~~~~~~~~~~~~

Second release candidate for 26.0. Fixed a regression in (private)
``Version._key`` for ``packaging_legacy`` (:pull:`1048`), and speed up
stripping zeros a little more (:pull:`1058`).

26.0rc1

~~~~~~~~~~~~~~~~~~~~

First release candidate for 26.0.
