Changelog

Sourced from setuptools's changelog.

v84.0.0

Features

• Newline-separated keywords and platformspypa/setuptools#4887old specification <https://peps.python.org/pep-0345/>_ separated items with spaces and the current one uses commas. (#4887)
• Extensionpypa/distutils#373#5022)
• The C compiler modules now emit log messages through their own compilers.C.* loggers instead of the distutils root logger, part of decoupling the compilers package from distutils. The logger names are normalized to a stable compilers.C.* prefix so they remain constant as the package migrates toward a standalone compilers.C distribution. (#5266)
• The C compilers gained a Compiler.call method -- a thin wrapper over subprocess.check_call (with macOS deployment-target env injection) that is the modern replacement for Compiler.spawn. The compilers no longer depend on distutils.spawn, distutils.dir_util, distutils.file_util, distutils._modified, or distutils.util.execute/split_quoted: the generic newer/newer_group and split_quoted helpers are vendored into the compilers package, and Compiler.mkpath/move_file/execute are implemented directly on the standard library (os.makedirs/shutil.move). The methods are retained for backward compatibility. (#5267)
• The compilers no longer depend on distutils.util, distutils.version, distutils.compat, or distutils._macos_compat. The platform-identification helpers (get_platform/get_host_platform/is_mingw) now live in distutils.compilers.platform.detect and the macOS deployment-target logic and compiler_fixup in distutils.compilers.platform.macos; CygwinCCompiler.gcc_version returns a packaging.version.Version. distutils.util re-exports the platform/macOS helpers from their new homes for backward compatibility rather than keeping duplicate copies. (sysconfig lookups still route through distutils pending its own decoupling.) (#5268)
• The compilers now read their build configuration from the standard library's sysconfig instead of distutils.sysconfig. Per-compiler customization -- previously distutils.sysconfig.customize_compiler -- has moved into Compiler.configure_system(): a no-op on the base class, with UnixCCompiler applying the compiler/flag/archiver settings CPython recorded in sysconfig (and the usual CC/CFLAGS/LDSHARED/… environment overrides). distutils.sysconfig.customize_compiler is retained as a thin wrapper that calls compiler.configure_system(). (#5269)

Bugfixes

• The MSVC linker now passes its arguments through a response file when the command line would exceed the Windows maximum length, fixing failures when linking a large number of objects. (#4177)
• The Cygwin and MinGW compilers now pass -O1 instead of a bare -O. The two are equivalent to GCC, but cc1 rejected the bare form when building 32-bit extensions with -m32. -- by :user:dchaudhari7177 (#4873)
• copy_filepypa/distutils#379#5079)
• Setuptools wheels no longer bundled the project's own test modules. -- by :user:itscloud0 (#5212)
• build_ext no longer fails when cross-compiling with a compiler other than MSVC (such as MinGW). Compiler now provides a no-op initialize()pypa/distutils#399

Improved Documentation

• Clarified what "correspond exactly to the directory structure" means in the packages section of the Package Discovery user guide. (#4109)
• Documented how bdist_wheel's py_limited_api option controls abi3 wheel tagging for extension modules -- by :user:Himanshuagrawal4 (#4741)

Deprecations and Removals

• Compiler.spawn is deprecated in favor of the new Compiler.call. call raises native subprocess exceptions; spawn remains as a shim that emits a DeprecationWarning and translates them to DistutilsExecError. The MSVC spawn compatibility shim for third-party monkeypatches predating the env argument (numpy.distutils before 1.19, per pypa/distutils#15) has been removed. distutils.spawn.spawn is likewise reduced to a thin wrapper around subprocess.check_call: it no longer resolves cmd[0] via shutil.which (subprocess searches PATH itself) nor injects MACOSX_DEPLOYMENT_TARGET (that now lives with the compilers, the only callers to which it applied). (#5267)
• Building an extension with a MACOSX_DEPLOYMENT_TARGET lower than the interpreter's configured value now raises compilers.errors.PlatformError instead of distutils.errors.DistutilsPlatformError (the macOS deployment-target check moved into the compilers package). CygwinCCompiler.gcc_version returns a packaging.version.Version rather than the removed distutils.version.LooseVersion. Completing the transition begun in pypa/distutils#246, UnixCCompiler.runtime_library_dir_option now returns the ["-Wl,--enable-new-dtags", "-Wl,-rpath,<dir>"] list directly for GNU ld rather than collapsing it into a single string, and the temporary distutils.compat.consolidate_linker_args shim has been removed. (#5268)
• The compilers now define their own exception vocabulary instead of borrowing distutils' framework errors. Language-agnostic exceptions (Error, UnknownFileType, and a new PlatformError) live at distutils.compilers.errors, leaving room for future compilers.<language> siblings; the C/C++-specific CompileError/LinkError/LibError/PreprocessError remain in distutils.compilers.C.errors. The compilers now raise compilers.errors.PlatformError where they previously raised distutils.errors.DistutilsPlatformError/DistutilsModuleError, and compilers._modified.newer raises the stdlib FileNotFoundError. distutils.errors keeps its own framework exceptions and re-exports the compiler ones (CCompilerError, CompileError, etc.) for backward compatibility; because CCompilerError is compilers.errors.Error, code catching it (as distutils' top-level handlers do) still catches the new PlatformError. (#5270)
• customize_compiler now asserts that the compiler-related config variables (CC, CXX, CFLAGS, etc.) resolve to strings, raising AssertionError if any are unexpectedly Nonepypa/distutils#363

Updates coverage from 7.15.2 to 7.16.0

Release notes

Sourced from coverage's releases.

7.16.0

Version 7.16.0 — 2026-08-28

• When combining files, now path separator slashes will automatically be converted to the local file system style. This makes it less necessary to define [paths] configuration to combine data across operating systems. Fixes issue 2266.
• The Coverage.switch_context() method now returns the previous context.
• Fix: previously, a [paths] pattern would be replaced everywhere in a file path when it was only meant to be replaced once, in the leading portion of the path. This is now fixed, in pull 2268.
• Fixes to validation of options and configuration settings:
  • Negative precision settings now always cause useful error messages (pull 2261).
  • An invalid regex in the --contexts option (or the [report] contexts setting) reported a confusing “Couldn’t use data file …: user-defined function raised exception” error. Now it raises a proper configuration error naming the bad regex, like other regex settings do (pull 2262).
  • Non-string values in TOML configuration settings now produce a helpful error message instead of a traceback. This affects list settings whose elements aren’t strings (like omit, exclude_lines, or a [paths] entry), file settings like data_file, and any wrong-typed value in the [paths] section (pull 2263).
  • coverage run refuses run-affecting command-line options like --branch alongside --concurrency=multiprocessing, since they can’t reach the subprocesses. The check only recognized multiprocessing as the entire option value, so --concurrency=multiprocessing,thread slipped through and failed later with “Can’t combine statement coverage data with branch data”. Each named concurrency library is now properly considered (pull 2270).
• Fix: coverage annotate -d DIR raised an AssertionError if any measured file had an extension other than .py, such as a .pyw file on Windows. The original extension is now restored on the annotated copy (pull 2265).

7.15.4

Version 7.15.4 — 2026-08-06

• Fix: in the HTML report, a source file name containing a double quote (legal on POSIX) wasn’t escaped where it’s dropped into the href of the index and prev/next links, so it could close the attribute early and inject markup. Page URLs are now escaped. Thanks, Rajath Mohare.
• Fix: the LCOV report wrote file names and other fields into its line-oriented records without neutralizing control characters. A measured file whose name contained a newline (legal on POSIX) could forge extra records, inflating the coverage seen by tools that read the report. Control characters in a field are now replaced. Thanks, Rajath Mohare.
• Wheels are now provided for Python 3.15.

7.15.3

Version 7.15.3 — 2026-08-02

• Fix: the sysmon core is incompatible with dynamic contexts. Previously, the combination would be prevented when read from the coverage.py configuration. But using the context API as pytest-cov does, contexts would be silently dropped. Now a warning is issued, thanks to Jisang Han. Closes issue 2200.
• A performance improvement in the low-level line number bookkeeping when combining data files, thanks to Kevin Turcios.
• Performance improvement in HTML reporting by reducing the number of times files have to be parsed, thanks to Kevin Turcios.

Updates charset-normalizer from 3.4.9 to 3.5.1

Release notes

Sourced from charset-normalizer's releases.

Version 3.5.1

3.5.1 (2026-08-15)

Changed

• Raised upper bound of setuptools to v84 (#794)
• Cache performance access optimization for our CharInfo struct (prebuilt only).

Fixed

• No longer decoding large content when the noise detector output give a high entropy. Only impacted large content input >1M bytes.

Version 3.5.0

3.5.0 (2026-08-12)

Added

• Explicit support for Python 3.15

Fixed

• Comparing a CharsetMatch to a non-alias encoding strings (#773)
• Return 0.0 CharsetMatch.multi_byte_usage for empty payloads instead of crashing (#774)
• A file with both a charset declaration and BOM/SIG did not verify first the BOM/SIG charset.
• iso2022* cases misdetected due to a flaw in our multibyte chunking logic.

Changed

• Replaced the optional mypyc build with Cython extensions while retaining the pure Python fallback. The previous engine (mypyc) started to hit rough limit around the optimization of our noise/coherence detector while Cython allows us to steer the engine toward the right generated optimized sources. This change SHOULD not impact bundler (e.g. Pyinstaller) as the module are immediately discoverable (i.e. not hidden import like mypyc did). Moreover, a long wished distribution is the abi3 wheels, this will allow us to no longer rush each year when a new Python interpreter is released. We still distribute the interpreter specific wheels for faster performance.
• Applied micro-optimization on several utils.
• CharsetMatches no longer sort on each match insertion.

Misc

• Removed an old performance optimization attempt in apy.py (success_fast_tracked+payload_result_cache).

Updates idna from 3.18 to 3.19

Release notes

Sourced from idna's releases.

v3.19

• Restore the std3_rules option, which had no effect since changes to UTS #46 processing in Unicode 16. Note that uts46_remap() defaults to enabling STD3 rules, so direct callers will see input containing non-LDH ASCII characters rejected again.
• Performance improvements to UTS #46 mapping, particularly for ASCII-only domains.
• Test on free-threaded CPython with the GIL disabled and document thread safety.
• Expose the Unicode version of the generated tables as idna.unicode_version, and show it in idna --version.
• Add code, text, codepoint and position attributes to IDNAError so that the failed rule and the offending character can be identified without parsing the exception message.
• The deprecated transitional argument to encode() and uts46_remap() is now completely ignored, and gives a deprecation warning for the latter.
• Reject A-labels that are not the canonical Punycode encoding of their U-label.
• Fix CONTEXTJ violations raising IDNAError instead of InvalidCodepointContext.
• Consistently raise IDNAError for empty labels and non-ASCII bytes passed to label helper functions and the incremental codec.
• Add property-based tests, extended fuzzing targets, coverage measurement, and CI checks that the data tables match the generator output.
• Various code quality and tooling improvements.

Updates 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)

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

tags on Linux. (:issue:160)

Fixes for versions and specifiers:

Raise InvalidVersion instead of TypeError when Version is given a

non-string. (:pull:1319)
Raise InvalidVersion for non-string pre-release letters passed to

Version.from_parts. (:pull:1241)
Fix an AttributeError when hashing internally trimmed versions.

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

intersections. (:pull: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. (:pull:1232)
