[dependabot]

Bumps packaging from 26.2 to 26.3.

Release notes

Sourced from packaging's releases.

26.3

What's Changed

Features

• Add a public VersionRange API and SpecifierSet.to_range(), representing the versions a specifier set accepts as an interval set that supports intersection, union, difference, complement, set relations, membership tests, and filtering. VersionRange.to_specifier_set() converts a range back to a SpecifierSet where a PEP 440 form exists. (#1267, #1270, #1298)
• PEP 808: accept Metadata-Version: 2.6. (#1194)
• Add a limit argument to parse_tag() for compressed tag sets. (#1220)
• Add a prefer_sdist_predicate argument to Pylock.select() to prefer source distributions over wheels for selected packages. (#1334)
• Add pure_python_tags() to generate the pure-Python tags for a Python version without touching the running platform. (#1346)
• Add SpecifierSet.is_subset(), SpecifierSet.is_superset(), and SpecifierSet.is_disjoint(), which compare the versions two specifier sets accept. (#1313)

Behavior adaptations

• Drop support for Python 3.8; packaging now requires Python 3.9 or later. (#1157)
• Prefer native linux_* platform tags over manylinux and musllinux tags on Linux. (#160)

Fixes for versions and specifiers

• Raise InvalidVersion instead of TypeError when Version is given a non-string. (#1319)
• Raise InvalidVersion for non-string pre-release letters passed to Version.from_parts. (#1241)
• Fix an AttributeError when hashing internally trimmed versions. (#1242)
• Fix SpecifierSet.is_unsatisfiable for post-release boundary intersections. (#1257)

Fixes for requirements and markers

• Make Requirement.__hash__ consistent with __eq__ for trailing-zero-equivalent specifiers (e.g. foo==1.0.0 and foo==1.0.0.0), so equal requirements hash equal and deduplicate in sets and dicts. (#1232)
• Normalize requested extra names before comparing or hashing requirements. (#644)
• Preserve a Requirement's specifier prereleases override across a pickle round trip. (#1204)
• Raise InvalidRequirement instead of InvalidSpecifier when a requirement contains an invalid specifier. (#1332)
• Clarify the error for post-release prefix wildcards like ==1.0.post1.*. (#1299)
• Preserve quoting semantics when serializing marker values, so round-tripped markers parse back to the same marker. (#1213)
• Keep the parentheses of a nested group when serializing markers. (#1316)
• Normalize extra and dependency_groups values in nested markers at parse time. (#1246, #1310)
• Raise UndefinedComparison when a set-valued variable like extras is used outside the membership form. (#1265)
• Raise UndefinedEnvironmentName (a KeyError subclass) for missing environment keys during marker evaluation. (#1276)
• Wrap malformed string literal errors in InvalidMarker / InvalidRequirement instead of leaking a low-level error. (#1249)
• Reject requirements and markers with a trailing line break. (#1345)

Fixes for metadata and licenses

• Collect all from_email validation errors into one ExceptionGroup instead of raising the first. (#1268)
• Accept the UTF-8 charset case-insensitively in email payloads. (#1330)
• Reject malformed Description-Content-Type values. (#1329)
• Don't rewrite user values that contain {field} placeholders in error messages. (#1327)
• Route multipart email payloads to unparsed instead of asserting. (#1247)
• Make InvalidMetadata and CyclicDependencyGroup picklable. (#1328)
• Fold every line boundary str.splitlines recognizes when writing a header with RFC822Message. (#1356)

26.3 - 2026-08-03

Features:

Add a public :class:~packaging.ranges.VersionRange API and

:meth:SpecifierSet.to_range() <packaging.specifiers.SpecifierSet.to_range>,

representing the versions a specifier set accepts as an interval set that

supports intersection, union, difference, complement, set relations,

membership tests, and filtering.

:meth:~packaging.ranges.VersionRange.to_specifier_set converts a range back

to a :class:~packaging.specifiers.SpecifierSet where a PEP 440 form exists.

(:pull:1267, :pull:1270, :pull:1298)
PEP 808: accept Metadata-Version: 2.6. (:pull:1194)
Add a limit argument to parse_tag() for compressed tag sets.

(:issue:1220)
Add a prefer_sdist_predicate argument to Pylock.select() to prefer

source distributions over wheels for selected packages. (:pull:1334)
Add :func:~packaging.tags.pure_python_tags to generate the pure-Python

tags for a Python version without touching the running platform.

(:pull:1346)
Add :meth:SpecifierSet.is_subset() <packaging.specifiers.SpecifierSet.is_subset>, :meth:~packaging.specifiers.SpecifierSet.is_superset,

and :meth:~packaging.specifiers.SpecifierSet.is_disjoint, which compare the

versions two specifier sets accept. (:pull:1313)

Behavior adaptations:

Drop support for Python 3.8; packaging now requires Python 3.9 or later.

(:pull:1157)
Prefer native linux_* platform tags over manylinux and musllinux

(:pull:1242)
Fix SpecifierSet.is_unsatisfiable for post-release boundary

intersections. (:pull:1257)

trailing-zero-equivalent specifiers (e.g. foo==1.0.0 and

foo==1.0.0.0), so equal requirements hash equal and deduplicate in
