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 cffi from 2.1.0 to 2.1.1

Release notes

Sourced from cffi's releases.

v2.1.1

What's Changed

• Minimize internal Python API usage for interpreter and thread state sampling where possible. Avoids breaking ABI change in Python >= 3.15.0b4 (python-cffi/cffi#269).

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 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)

Version 8.5.0

Released 2026-08-24

• 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. {issue}2672 {pr}3637

Updates dependency-groups from 1.3.1 to 1.3.2

Release notes

Sourced from dependency-groups's releases.

1.3.2

• Add support for Python 3.14 and 3.15
• Remove support for Python 3.8
• Correct the type of the dependency_groups parameter to resolve(), resolve_all(), and DependencyGroupsResolver().
• Raise a clear TypeError when an include-group value is not a string (was a cryptic TypeError from name normalization), and accept any Mapping for include items, not only dict.
• Fix a bug in which pip-install-dependency-groups failed when the resolved groups were empty. It now prints Nothing to install and exits normally.
• dependency-groups --list now respects the -o/--output option.
