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.

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.

intersections. (:pull:1257)

Sourced from hatch's releases.

Hatchling v1.18.0

Changed:

• Drop support for Python 3.7

Added:

• Update the list of directories that are always excluded for builds

Hatch v1.18.0

Changed:

• Upgrade default CPython distributions to 20260807

Added:

• Add the sources environment option, which redirects dependencies to a local path, Git repository, URL, alternate index, or workspace member at install time without altering published metadata. The top-level [tool.hatch.sources] table is an alias for the default environment, environments inherit sources entry by entry, the HATCH_NO_SOURCES environment variable disables them, and hatch dep show sources reports what each source redirects

• Add the --all/-a flag to the build command to build the workspace root and every workspace member defined by the selected environment, consolidating artifacts in the workspace root's dist directory by default. A root that does not define a project table is skipped so that a top-level pyproject.toml may only contain workspace configuration

• Add the tool.hatch.requires-hatch field, a version specifier set that commands reading the project's metadata enforce against the running version of Hatch

• Add first-class support for free-threaded distribution names such as 3.13t and 3.14t to the python commands and environment python option, rather than requiring the HATCH_PYTHON_VARIANT_GIL environment variable

• The version command can now bump versions that are statically defined by the project.version field, updating pyproject.toml in place. Pass --force to allow an explicit downgrade

• Support managing Python 3.15 distributions, currently 3.15.0rc1

Fixed:

• Erase stale coverage data before running hatch test --cover.

• Fix environment creation crashing when a metadata hook exists that doesn’t happen to be installed in the hatch CLI’s environment.

• Fix commands run by hatch run no longer being interruptible with Ctrl-C, which happened because the ignored SIGINT of the parent process was inherited by the child process.

• Fix the generated Pyrefly config being invalid on Windows, since backslashes in the absolute paths were interpreted as TOML escape sequences.

• Fix the hardcoded reliance on pip when installing dependencies internally by using uv instead.

• Fix environment creation silently installing a GIL-enabled Python distribution when Hatch itself runs on a free-threaded build. The distribution matching the running interpreter, such as 3.14t, is now selected.

• Fix free-threaded selectors such as 3.14t being rejected by an environment's python option, even though hatch python install 3.14t already accepted them.

• Never automatically select a prerelease Python distribution, such as 3.15.0rc1, when falling back to the latest compatible version. A prerelease is still installed when requested explicitly.

Hatchling v1.32.0

Changed:

• Bump default core metadata version to 2.5

• Add tomlkit as a runtime dependency, which is required to rewrite pyproject.toml when setting a static version

Added:

• The version command can now set a version that is statically defined by the project.version field, updating pyproject.toml in place. Pass --force to allow an explicit downgrade

Fixed:

• Allow the ; private annotation on project.import-names and project.import-namespaces entries rather than rejecting them as invalid import names.

• Reject project.readme paths that are absolute or resolve outside of the project directory.
