Updates gunicorn from 26.0.0 to 26.2.0

Release notes

Sourced from gunicorn's releases.

gunicorn 26.2.0

Cleartext HTTP/2 lands, and an HTTP/2 security fix.

Cleartext HTTP/2 (h2c)

http2_cleartext accepts prior-knowledge, upgrade, both or off (the default). Prior knowledge serves a connection that opens with the HTTP/2 preface; upgrade honours an HTTP/1.1 Upgrade: h2c request. Both work on the gthread, gevent and asgi workers.

This is for deployments where TLS is terminated by a proxy that speaks HTTP/2 upstream, so the hop into gunicorn no longer drops to HTTP/1.1. Only peers in forwarded_allow_ips are considered; everyone else is served HTTP/1.x exactly as if the setting were off. Each mechanism is enabled separately, so turning one on does not turn the other on.

Do not expose a cleartext HTTP/2 port to the internet.

Security

HTTP2Request built its headers straight from the stream, so nothing the HTTP/1 path enforces applied over HTTP/2: the underscore and header_map policy, duplicate Host and Content-Type, control characters in values, and the forwarded_allow_ips trust gate. An untrusted client could set SCRIPT_NAME and forge HTTP_* entries in the WSGI environ, and decide wsgi.url_scheme through :scheme. Both request classes now share one policy mixin, and the scheme comes from the transport.

If you serve HTTP/2, this is the reason to upgrade.

Other HTTP/2 fixes

WSGI responses were buffered whole before anything was sent; they stream now. HEAD, 204 and 304 no longer carry a body. Events read while blocked on a flow-control window were discarded, losing requests and body data outright. sendfile() is refused on HTTP/2 responses rather than bypassing framing.

Request bodies dropped on Upgrade requests

On the ASGI worker with the fast parser, any request carrying an Upgrade header reached the application with an empty body, whatever the header's value and with HTTP/2 switched off entirely. Fixed in gunicorn_h1c 0.6.9, which the fast extra now requires.

Updates numpy from 2.5.0 to 2.5.3

Release notes

Sourced from numpy's releases.

v2.5.3 (Sep 6, 2026)

NumPy 2.5.3 Release Notes

The NumPy 2.5.3 is a patch release that fixes bugs discovered after the 2.5.2 release. Apart from the usual bug and maintenance work, there are a number of StringDType related fixes for problems discovered during the ongoing string work in the main branch.

This release supports Python versions 3.12-3.15

Changes

• Casting a fixed-width byte string array (np.bytes_) to StringDType now raises TypeError when the bytes are not valid UTF-8. Previously the invalid bytes were stored as-is and later caused undefined behavior in string operations.

  (gh-32296)

• MaskedArray._fill_value would become stale when ufuncs that change dtype left the result holding a fill_value typed for the old dtype. The mismatch was silent until something later called _check_fill_value, such as .view(), and then a TypeError would be raised. Now, when the copied fill_value is no longer valid for the new dtype, fall back to the default fill_value for that dtype instead of propagating the stale value. This may raise a ComplexWarning if the fill_value is complex and the new dtype is real.

Updates charset-normalizer from 3.4.7 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).

Version 3.4.9

3.4.9 (2026-07-07)

Fixed

• Regression in our fallback path leading to a decode error. (#771) We've yanked 3.4.8 as a result of that bug.

Version 3.4.8

3.4.8 (2026-07-06)

Updates click from 8.4.2 to 8.5.0

Release notes

Sourced from click's releases.

8.5.0

This is the Click 8.5.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecation, or introduce potentially breaking changes.

We encourage everyone to upgrade. You can read more about our Version Support Policy on our website.

PyPI: https://pypi.org/project/click/8.5.0/ Changes: https://click.palletsprojects.com/page/changes/#version-8-5-0 Milestone https://github.com/pallets/click/milestone/33

• Add built-in shell completion support for PowerShell (Windows PowerShell 5.1+ and pwsh 7+) alongside the existing bash, zsh, and fish completers. Use _FOO_BAR_COMPLETE=powershell_source foo-bar to generate the completion script. #2672 #3637
• Supported versions of Windows enable ANSI terminal styles by default. Colorama is no longer a dependency and is not used. #2986 #3505
• {class}Argument accepts a help parameter, and help output includes a Positional arguments section when argument help is available. #2983 #3473
• confirm() and prompt() strip ANSI color and style codes from the prompt when the output stream does not support them, matching echo(). This stripping was lost in 8.4.0 when #2969 began writing the prompt with input() directly. #3572 #3653
• {class}Path with allow_dash=True no longer triggers a BytesWarning, an error under python -bb, when checking a value against the - convention. #2877 #3642
• Add {func}custom_version_option, a --version option whose output is produced by a callback, covering cases {func}version_option intentionally does not. The feature set of {func}version_option is now frozen; see [discussion #3527](https://github.com/pallets/click/discussions/3527). #3581
• style() and secho() no longer silently drop the 256-color index 0 (black) passed as fg or bg, and now validate color arguments. Invalid colors raise a ValueError instead of a TypeError. #3677
• The automatic help option stores its value under the reserved name _click_default_help instead of help, so a parameter named help no longer breaks parsing. The new name is visible in {meth}Command.to_info_dict output. Parameters that overwrite each other's value trigger a warning: an argument sharing its name with another parameter, or any parameter claiming the reserved name. Options may still share a name to compete for the same value (feature switches). #2819 #3678
• unstyle and the ANSI handling behind help-text wrapping now strip the full CSI escape-sequence grammar. #3681
• Streamline Option flag handling: the flag-kind, type, lazy-default and validation steps in Option.__init__ move into focused helpers, and flag_value and default keep their unset sentinel at construction (resolved lazily on read) so is UNSET reliably tells a user-supplied value from an auto-derived one. Runtime behavior is unchanged, but {meth}Parameter.to_info_dict now resolves default=True on a feature switch to its flag_value, matching what the function receives at call

Updates idna from 3.18 to 3.20

Release notes

Sourced from idna's releases.

v3.20

• Update to Unicode 18.0.0.
• Better enforcement of the domain length limit in the incremental codec.
• Add support for Python 3.15.

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 joblib from 1.5.3 to 1.6.0

Changelog

Sourced from joblib's changelog.

Release 1.6.0 - 2026/08/31

• Fix caching of functions whose source cannot be retrieved, such as functions defined in a notebook cell. Their identity fell back to str(hash(func.__code__)), which is salted by PYTHONHASHSEED and so differed between processes. A worker reading the func_code.py written by another one concluded that the function had changed and wiped the whole cache directory for it, discarding results computed by its peers. func_code.py is also no longer rewritten in place, so a reader can no longer catch it half-written and draw the same conclusion. joblib/joblib#1694

• Drop python 3.9 support. The oldest supported Python version is now Python 3.10. joblib/joblib#1773

• Fix eval_expr (used to evaluate the pre_dispatch argument of Parallel) to raise a ValueError as documented instead of leaking a ZeroDivisionError for expressions that divide or take a modulo by zero. joblib/joblib#1810

• MemorizedResult now forwards mmap_mode to its store backend, so a cached array reconstructed from a location is memory-mapped as requested instead of being loaded fully into memory. joblib/joblib#1799

• Unvendor cloudpickle to more quickly benefit from maintenance releases of cloudpickle joblib/joblib#1775

• Fix Memory.cache for functions with a keyword-only argument that has a default declared before a keyword-only argument without a default. joblib/joblib#1731

• Fix behavior of filter_args on some precise cases. joblib/joblib#1800

• Fix a concurrency error that could happen with unordered generator. joblib/joblib#1789

• Fix: dump() now accepts any input os.PathLike object to be consistent with load. joblib/joblib#1812

• The documentation now uses pydata sphinx theme. Furthermore, optional dependencies test and docs have been added to pyproject.toml. joblib/joblib#1774

• Vendor loky 3.6.0

Release notes

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

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)
