v2.14.3 2026-11-04

v2.14.3 (2026-11-04)

What's Changed

Packaging

• Build wheels for GraalPy 3.13 by @​msimacek in #14136.

  The previous v2.14.2 release published GraalPy 3.11 wheels, which were not working due to a PyO3 version bump. A CI workflow issue made it so that the wheel wasn't tested before publishing. This is now fixed: starting in v2.14.3, we no longer publish GraalPy 3.11 wheels, and GraalPy 3.13 wheels are now published together with the existing 3.12 one.

Updates cbor2 from 6.1.5 to 6.2.0.post2

Release notes

Sourced from cbor2's releases.

6.2.0.post2

• Build Pyodide (pyemscripten) wheels for Python 3.14 (#351)

6.2.0

• Added the strict_hashable_types parameter to CBORDecoder, load and loads which, when enabled, restricts map keys and set elements to text strings and byte strings in order to prevent denial-of-service attacks via hash collisions (GHSA-p6xp-9h6j-r278)
• Documented decoding concatenated CBOR objects with EOF checks between objects (#30; PR by @​arindamsikder)
• Fixed CBOREncoder.encode_to_bytes() sharing the string reference namespace of the enclosing encode operation when called from a default hook (#356; PR by @​17krishna8)
• Fixed the encoder writing the repr() of a bytes regular expression pattern (tag 35) instead of the pattern itself, so the regular expression decoded back as the text pattern b'...' and no longer matched the same input (#355; PR by @​sahvx655-wq)
• Fixed shared references (tag 29) allowing the decoder to construct object graphs nested deeper than max_depth, which could crash the interpreter with a segmentation fault when such an object was hashed (as a map key or set member) (GHSA-55vx-2phh-7grr)
• Fixed mission conversion of date values (tags 100 and 1004) to JSON as ISO formatted strings (#358; PR by @​jadenfix)
• Fixed a PanicException on Python 3.10 when decoding a string-form datetime (tag 0) whose fractional seconds part contains a multi-byte Unicode numeric character, as the microsecond padding treated those as digits and then truncated the part on a byte index inside one of them (#354; PR by @​sahvx655-wq)
• Fixed the decoder accepting a set (tag 258) whose payload is not an array, folding a text string, byte string or map into a set of its characters, bytes or keys instead of rejecting it (#352; PR by @​sahvx655-wq)
• Fixed the decoder accepting a non-integer exponent or mantissa in a decimal fraction (tag 4) or a bigfloat (tag 5) (#350; PR by @​sahvx655-wq)

Commits

• 4ef9a50 Updated to the latest cibuildwheel action
• 5f63b56 Build pyemscripten wheels
• 2ad5850 Bumped up the version
• 1e709ca Require integer exponent and mantissa in tag 4 and tag 5 decoders (#350)
• da5033b Worked around Docker DNS lookup issue
• 2526221 Use host networking and fail on rustup errors
• 37ce899 reject non-array payloads in the set decoder (tag 258) (#352)
• a24e136 Isolate string references in encode_to_bytes from the outer namespace (#356)
• 2af101a Fixed PanicException on non-ASCII digits in a tag 0 datetime (#354)

Updates pytest from 9.1.1 to 9.2.0

Release notes

Sourced from pytest's releases.

9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.

Updates click from 8.5.0 to 8.5.1

Release notes

Sourced from click's releases.

8.5.1

This is the Click 8.5.1 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/8.5.1/ Changes: https://click.palletsprojects.com/page/changes/#version-8-5-1 Milestone: https://github.com/pallets/click/milestone/66

• Fix copy.deepcopy() and pickle on a Parameter, Option or Command. #3805
• A KeyboardInterrupt arriving while Command.main() reports an abort or an error, or while it exits, no longer escapes as an unhandled traceback. The command still exits with the intended code; only the message may be lost. #3802
• Add Option.get_help_spec(), which returns the option's left help column even when the option is hidden. Option.get_help_record() still returns None for hidden options, so help screens are unchanged. #3821
• The Positional arguments help section lists every argument of the command, not only the documented ones. An argument with no help gets an empty description, the same way an option with no help does. #3860
• Argument.get_help_record() always returns a tuple. It used to return None for an argument with no help. #3860
• Document which types are inferred from default, and what an unrecognized type callable does to a command-line value. #3036 #3808
• path_type narrows the converted value's type for convert and prompt. #3822 #3858
• Parameter accepts a new help argument, and Option and Argument inherit it. Parameter.to_info_dict() now reports help for every kind of parameter. #3861
• A command's short help no longer stops at an abbreviation such as vs. or e.g. inside the first sentence. A period ends the sentence only when it closes the text or the next word does not start in lowercase. #3865
• With show_envvar=True, an option's error message now prints all variables of an envvar sequence instead of the repr of the sequence. #3884
• An empty envvar, such as [] or "", shows the same help and error message as no envvar when show_envvar=True. The help screen used to show [env var: ]. #3884
• Align command's deprecated help text to options and arguments: do not translate the command's own help text, only the (DEPRECATED) label. #3901

• With show_envvar=True, an option's error message now prints all variables of an envvar sequence instead of the repr of the sequence. {pr}3884
• An empty envvar, such as [] or "", shows the same help and error message as no envvar when show_envvar=True. The help screen used to show [env var: ]. {pr}3884
• Align command's deprecated help text to options and arguments: do not translate the command's own help text, only the (DEPRECATED) label. {pr}3901

Release notes

Sourced from markdown's releases.

Release 3.11.3

Fixed

• Fix cases in new emphasis handling that did not handle long chains of tokens like they should (#1690).
• Fix quadratic-time parsing of many consecutive reference definitions, and of many consecutive footnote definitions in the footnotes extension.
• Support automatic links with URL schemes other than HTTP and FTP, such as <ssh://example.org> (#1244).
• Fix quadratic-time id generation in the toc extension when many headers share the same text.
• Ignore glossary abbreviations with empty definitions after inline elements, consistently with abbreviations before inline elements.
• Strip complete HTML tags with quoted > characters from toc labels and generated heading IDs.
• Fix quadratic-time regex backtracking in attr_list when a block ends with an unclosed attribute list followed by a long run of spaces, e.g. a line consisting only of { and some text with many trailing spaces (#1656).
• Fix quadratic-time regex backtracking in hash headers when a long run of # characters is followed by more text on the same line.
• Fix quadratic time when a document contains many unclosed HTML comments (<!-- with no matching -->).
• Fix regression in BacktickInlineProcessor where text could be lost when opening and closing backticks did not match (#1668).
• Escape the language name in the codehilite extension's non-Pygments output to maintain consistency with Pygments output.
• Preserve attributes without a value in the attr_list extension exactly as provided, rather than rendering them as key="key", so the same source renders consistently under both the html and xhtml output formats (#1501).
