Updates black from 26.3.1 to 26.5.1

Release notes

Sourced from black's releases.

26.5.1

Stable style

• Fix unstable formatting of annotated assignments whose subscript annotation contains an inline comment (e.g. x: list[ # pyright: ignore[...]) (#5130)
• Preserve inline comments (including # type: ignore) immediately before a # fmt: skip line, avoiding AST equivalence failures (#5139)

Packaging

• Correct the version in the published executables (#5137)

Documentation

• Add Neovim integration guide covering conform.nvim, ALE, and simple command approaches (#5124)

26.5.0

Highlights

• Add support for unpacking in comprehensions (PEP 798) and for lazy imports (PEP 810), both new syntactic features in Python 3.15 (#5048)
• Python 3.15 is now supported. Compiled wheels are not yet provided for Python 3.15, so performance may be slower than on existing Python versions. Wheels will be provided once Python 3.15 is later in its release cycle. (#5127)

Stable style

• Fix # fmt: skip being ignored in nested if expressions with parenthesized in clauses (#4903)
• Add syntactic support for Python 3.15 (#5048)
• Fix crash when an f-string follows a # fmt: off comment inside brackets (#5097)
• Preserve multiline compound statement headers when # fmt: skip is placed on the colon line (#5117)

Preview style

• Improve heuristics around whether blank lines should appear before, within and after groups of same-name decorated functions (such as @overload groups) in .pyi stub files (#5021)
• Fix blank lines being removed between a function and a decorated class in .pyi stub files (#5092)
• Prevent string merger from creating unsplittable long lines when a pragma comment (e.g. # type: ignore) follows the closing bracket (#5096)

Packaging

• Run CI on 3.15 (#5127)

Updates coverage from 7.14.0 to 7.14.1

Changelog

Sourced from coverage's changelog.

Version 7.14.1 — 2026-05-26

• Fix: the HTML report used typographic niceties to make file paths more readable by adding a small amount of space around slashes. Those spaces interfered with searching the page for file paths of interest. Now the report uses CSS to accomplish the same visual tweak so that searches with slashes work correctly. Closes issue 2170_.

• Add a 3.16 PyPI classifier <hugo-316_>_ since we test on the 3.16 main branch.

Updates click from 8.3.3 to 8.4.1

Release notes

Sourced from click's releases.

8.4.1

This is the Click 8.4.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/click/8.4.1/ Changes: https://click.palletsprojects.com/page/changes/#version-8-4-1 Milestone: https://github.com/pallets/click/milestone/32?closed=1

• get_parameter_source() is available during eager callbacks and type conversion again. #3458 #3484
• Zsh completion scripts parse correctly on Windows. #3277 # 3466
• Shell completion of Choice Enum values produces a valid completion result. #3015
• Fix empty byte-string handling in echo. #3487
• Fix closed file error with echo_via_pager. #3449

8.4.0

This is the Click 8.4.0 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/8.4.0/ Changes: https://click.palletsprojects.com/page/changes/#version-8-4-0 Milestone https://github.com/pallets/click/milestone/30

• ParamType typing improvements. #3371

  • :class:ParamType is now a generic abstract base class, parameterized by its converted value type.
  • :meth:~ParamType.convert return types are narrowed on all concrete types (str for :class:STRING, int for :class:INT, etc.).
  • :meth:~ParamType.to_info_dict returns specific :class:~typing.TypedDict subclasses instead of dict[str, Any].
  • :class:CompositeParamType and the number-range base are now generic with abstract methods.

• Refactor convert_type to extract type inference into a private _guess_type helper, and add :func:typing.overload signatures. #3372

• Parameter typing improvements. #2805

  • :class:Parameter is now an abstract base class, making explicit that it cannot be instantiated directly.
  • :attr:Parameter.name is now str instead of str | None. When expose_value=False, the name is set to "" instead of None.
  • The ctx parameter of :meth:Parameter.get_error_hint is now typed as Context | None, matching the runtime behavior.

• Split string values from default_map for parameters with nargs > 1 or :class:Tuple type, matching environment variable behavior.

Updates idna from 3.14 to 3.18

Changelog

Sourced from idna's changelog.

3.18 (2026-06-02)

• When decoding a domain, add a display argument that will pass through invalid labels rather than raising an exception.

3.17 (2026-05-28)

• Substantial 75% reduction in memory usage through new data structures and some optimization in processing speed.
• Added a general 1024-character input length cap to the public validation, conversion, and codec entry points. This is well above any legitimate domain or label and guards against pathological inputs.

3.16 (2026-05-22)

• Add a command-line interface (python -m idna, also available as the idna script). Encodes or decodes one or more domains supplied as arguments or on standard input, with options to select A-label or U-label output and control error handling.
• Raise the minimum supported Python version to 3.9
• Various code quality improvements

3.15 (2026-05-12)

• Enforce DNS-length cap on individual labels early in check_label, short-circuiting contextual-rule processing for oversized input while staying compatible with UTS 46 usage.
• Tidy core helpers: hoist bidi category sets to module-level frozensets (avoiding per-codepoint list construction), simplify length checks, and reuse the shared _unicode_dots_re from idna.core in the codec module.
• Use raise ... from err for proper exception chaining and switch internal string formatting to f-strings.
• Allow flit_core 4.x in the build backend.
• Expand the ruff lint set (flake8-bugbear, flake8-simplify, pyupgrade, perflint) and apply the surfaced fixes; pin lint CI to Python 3.14.
• Add Dependabot configuration for GitHub Actions.
• Convert README and HISTORY from reStructuredText to Markdown.
• Reference CVE-2026-45409 for the 3.14 advisory in place of the initial GHSA identifier.

Thanks to Felix Yan, Stan Ulbrych, and metsw24-max for contributions to this release.

Updates chardet from 6.0.0.post1 to 7.4.3

Release notes

Sourced from chardet's releases.

7.4.3

Patch release: fixes a crash when input contains null bytes inside a <meta charset> declaration.

Bug Fixes

• Fixed ValueError: embedded null character crash when input contained a <meta charset> declaration with a null byte in the encoding name (e.g. b'<meta charset="\x00utf-8">'). codecs.lookup() raises ValueError on embedded nulls, and lookup_encoding() was only catching LookupError. Also added defensive ValueError catches in _validate_bytes() and _to_utf8() for completeness. (#369, thanks @​DRMacIver for the report)

Full Changelog: chardet/chardet@7.4.2...7.4.3

7.4.2

Patch release: fixes a crash on short inputs and closes a bunch of WHATWG/IANA alias gaps.

Bug Fixes

• Fixed RuntimeError: pipeline must always return at least one result on ~2% of all possible two-byte inputs (e.g. b"\xf9\x92"). Multi-byte encodings like CP932 and Johab could score above the structural confidence threshold on very short inputs, but then statistical scoring would return nothing, leaving an empty result list instead of falling through to the fallback. (#367, #368, thanks @​jasonwbarnett)

Improvements

• Added ~90 encoding aliases from the WHATWG Encoding Standard and IANA Character Sets registry so that <meta charset> labels like x-cp1252, x-sjis, dos-874, csUTF8, and the cswindows* family all resolve correctly through the markup detection stage. Every alias was driven by a failing spec-compliance test, not speculative. (#366)
• Added a spec-compliance test suite covering Python decode round-trips for all 86 registry encodings, WHATWG label resolution, IANA preferred MIME names, and Unicode/RFC conformance (BOM sniffing, UTF-8 boundary cases, UTF-16 surrogate pairs). This is the test suite that would have caught the 7.4.1 BOM bug before release. (#366)

Full Changelog: chardet/chardet@7.4.1...7.4.2

7.4.1

Bug Fixes

• BOM-prefixed UTF-16/32 input now returns utf-16/utf-32 instead of utf-16-le/utf-16-be/utf-32-le/utf-32-be. The endian-specific codecs don't strip the BOM on decode, so callers were getting a stray U+FEFF at the start of their text. BOM-less detection is unchanged. (#364, #365)

Full Changelog: chardet/chardet@7.4.0...7.4.1

chardet 7.4.0 brings accuracy up to 99.3% (from 98.6% in 7.3.0) and significantly faster cold start thanks to a new dense model format.

What's New

Performance:

• New dense zlib-compressed model format (v2) drops cold start (import + first detect) from ~75ms to ~13ms with mypyc

Accuracy (98.6% → 99.3%):

• Eliminated train/test data overlap via content fingerprinting
• Added MADLAD-400 and Wikipedia as supplemental training sources
• Improved non-ASCII bigram scoring: high-byte bigrams are now preserved during training and weighted by per-bigram IDF
• Encoding-aware substitution filtering (substitutions only apply for characters the target encoding can't represent)
• Increased training samples from 15K to 25K per language/encoding pair

Bug fixes:

• Added dedicated structural analyzers for CP932, CP949, and Big5-HKSCS (these were previously sharing their base encoding's byte-range analyzer, missing extended ranges)

7.4.3 (2026-04-13)

Bug Fixes:

• Fixed ValueError: embedded null character crash when input contained a <meta charset> declaration with a null byte in the encoding name (e.g. b'<meta charset="\x00utf-8">'). codecs.lookup() raises ValueError on embedded nulls, and lookup_encoding() was only catching LookupError. Also added defensive ValueError catches in _validate_bytes() and _to_utf8() for completeness. (Dan Blanchard <https://github.com/dan-blanchard>_ via Claude, [#369](https://github.com/chardet/chardet/issues/369) <https://github.com/chardet/chardet/issues/369>_)

7.4.2 (2026-04-12)

Bug Fixes:

• Fixed RuntimeError: pipeline must always return at least one result on ~2% of all possible two-byte inputs (e.g. b"\xf9\x92"). Multi-byte encodings like CP932 and Johab could score above the structural confidence threshold on very short inputs, but then statistical scoring would return nothing, leaving the pipeline with an empty result list instead of falling through to the no_match_encoding fallback. (Jason Barnett <https://github.com/jasonwbarnett>_ via Claude, [#367](https://github.com/chardet/chardet/issues/367) <https://github.com/chardet/chardet/issues/367>, [#368](https://github.com/chardet/chardet/issues/368) <https://github.com/chardet/chardet/pull/368>)

Improvements:

• Added ~90 encoding aliases from the WHATWG Encoding Standard and IANA Character Sets registry so that <meta charset> labels like x-cp1252, x-sjis, dos-874, csUTF8, and the cswindows* family all resolve correctly through the markup detection stage. Every alias was driven by a failing spec-compliance test. (Dan Blanchard <https://github.com/dan-blanchard>_ via Claude, [#366](https://github.com/chardet/chardet/issues/366) <https://github.com/chardet/chardet/pull/366>_)
• Added a spec-compliance test suite covering Python decode round-trips for all 86 registry encodings, WHATWG web-platform label resolution, IANA preferred MIME names, and Unicode/RFC conformance (BOM sniffing, UTF-8 boundary cases, UTF-16 surrogate pairs). This is the test suite that would have caught the 7.4.1 BOM bug before release.
