Release notes

Sourced from pytest's releases.

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

9.1.0

pytest 9.1.0 (2026-06-13)

Removals and backward incompatible breaking changes

• #14533: When using --doctest-modules, autouse fixtures with module, package or session scope that are defined inline in Python test modules (not plugins or conftests) will now possibly execute twice.

  If this is undesirable, move the fixture definition to a conftest.py file if possible.

  Technical explanation for those interested: When using --doctest-modules, pytest possibly collects Python modules twice, once as pytest.Module and once as a DoctestModule (depending on the configuration). Due to improvements in pytest's fixture implementation, if e.g. the DoctestModule collects a fixture, it is now visible to it only, and not to the Module. This means that both need to register the fixtures independently.

Deprecations (removal in next major release)

• #10819: Added a deprecation warning for class-scoped fixtures defined as instance methods (without @classmethod). Such fixtures set attributes on a different instance than the test methods use, leading to unexpected behavior. Use @classmethod decorator instead -- by yastcher.

  See 10819 and 14011.

• #12882: Calling request.getfixturevalue() <pytest.FixtureRequest.getfixturevalue> during teardown to request a fixture that was not already requested is now deprecated and will become an error in pytest 10.

  See dynamic-fixture-request-during-teardown for details.

• #13409: Using non-~collections.abc.Collection iterables (such as generators, iterators, or custom iterable objects) for the argvalues parameter in @pytest.mark.parametrize <pytest.mark.parametrize ref> and metafunc.parametrize <pytest.Metafunc.parametrize> is now deprecated.

  These iterables get exhausted after the first iteration, leading to tests getting unexpectedly skipped in cases such as running pytest.main() multiple times, using class-level parametrize decorators, or collecting tests multiple times.

  See parametrize-iterators for details and suggestions.

• #13946: The private config.inicfg attribute is now deprecated. Use config.getini() <pytest.Config.getini> to access configuration values instead.

  See config-inicfg for more details.

• #14004: Passing baseid to ~pytest.FixtureDef or nodeid strings to fixture registration APIs is now deprecated. These are internal pytest APIs that are used by some plugins.

v3.16.0

2026-09-27

• #604: Fixed duplicate_iterators=True for async functions spied with mocker.spy.
• #611: Fixed async mock assertion introspection to use awaited arguments instead of the latest call's arguments.
• #606: mocker.resetall(return_value=True, side_effect=True) now also applies to non-callable mocks, such as those returned by mocker.create_autospec(SomeClass, instance=True). Previously both arguments were silently ignored for them.
• #547: Added SpyType for annotating mocker.spy results.

Updates torch from 2.14.0 to 2.14.1

Release notes

Sourced from torch's releases.

PyTorch 2.14.1 Release

This release is meant to fix the following regressions and silent correctness issues:

Silent correctness fixes

• Fix incorrect torch.linalg.lstsq solutions on MPS for complex batched underdetermined systems (#196113), fixed by #196128
• Fix non-orthogonal U and inaccurate small singular values from torch.linalg.svd on MPS for rank-deficient and ill-conditioned inputs (#196112), fixed by #196139 and #199063
• Update the CUDA 13.2 Linux binaries to CUDA 13.2.2 (#196351). This NVIDIA update resolves two critical issues that could produce incorrect results (CUDA 13.2.2 release notes):
  • cuBLAS: cublasLtMatmul() could ignore tensor-wide scaling for NVFP4 matrix multiplications (introduced in CUDA 13.2 Update 1)
  • Compiler: failed thread reconvergence could leave stale or corrupted register values in kernels with nested thread divergence (present since CUDA 12.8)

Regression fixes

• Fix torch.linalg.svd, torch.linalg.svdvals and torch.linalg.lstsq failing on MPS with a Metal pipeline-state error for inputs above 8192 elements (#195937), fixed by #195949 and #195950
• Fix internal assert in torch.svd(out=) on MPS for complex inputs (#195822), fixed by #195872

Updates mcp from 2.1.1 to 2.3.0

Release notes

Sourced from mcp's releases.

v2.3.0

pip install -U mcp. Docs: https://py.sdk.modelcontextprotocol.io/

Mostly fixes, plus three new options. A few things behave differently, so skim these first:

Behaviour changes

httpx2>=2.10.0 is now required (#3600)

• It was >=2.5.0. The new max_sse_event_size option needs it.
• Nothing to do unless you pin httpx2 below 2.10.

A tool with an invalid x-mcp-header annotation fails at registration (#3620)

• @mcp.tool(), add_tool and Tool.from_function raise InvalidSignature, naming the tool and the problem.
• Until now the server started, and 2026-07-28 clients silently dropped the tool from their listing.
• Refused: anything other than a plain str, int or bool parameter (so also str | None, float, lists and enums), a header name that isn't a valid token, and two names that differ only by case.
• For an optional header parameter, give the schema directly: Annotated[str | None, WithJsonSchema({"type": "string", "x-mcp-header": "Region"})] = None.

Empty _meta and params are no longer sent (#3628)

• On 2025-11-25 and earlier connections, 2.x sent "_meta": {} on every request. Some servers reject that. It is now left out, as in v1.
• ping and list requests without a cursor go out with no params member.
• On the receiving side ctx.meta is None rather than {}, and middleware sees ctx.params as None for a request without params.
• 2026-07-28 connections are unchanged.

initialize leaves out experimental when none is configured (#3614)

• It used to send "experimental": {}. server/discover already left it out.
• Client code reading capabilities.experimental on a legacy connection should handle None.

Mcp-Param-* validation looks the tool up by name (#3630)

• MCPServer no longer runs tools/list for every tools/call, so middleware no longer sees that extra request.
• The registered schema is what gets checked. Middleware that filters or rewrites tools/list no longer affects it.

An interactive OAuth login no longer counts against request timeouts (#3635)

• The timeout pauses while OAuthClientProvider waits on redirect_handler and callback_handler.
• This fixes Client(mode="auto") settling on 2025-11-25 when the login took longer than 10 seconds.
• A request timeout no longer ends a login nobody finishes. Put a limit inside callback_handler if you need one.

New

• max_sse_event_size= on streamable_http_client and StreamableHttpParameters. The default stays 1 MiB per SSE event; raise it, or pass None, for larger tool results (#3600).
• MCPServer(subscriptions=False) stops serving subscriptions/listen and advertises listChanged and subscribe as false (#3626).
• Server(get_tool_input_schema=...) lets a low-level server supply a tool's schema for header validation without running its tools/list handler (#3630).
• Client.call_tool re-lists the tools and retries once after a HeaderMismatch (-32020) rejection (#3627).

Fixes

• ctx: Context[AppState] works on prompts and resource templates, not only on tools (#3624).
• An explicit "structuredContent": null is checked against the output schema instead of being treated as missing (#3621).
• A progress_callback that raises no longer fails the call on an in-process Client(server) (#3623).
• Client OpenTelemetry spans record JSON-RPC error responses. With mode="auto", connecting to a server without server/discover now shows one ERROR span for the probe (#3629).
• stdio_client resolves the executable off the event loop on Windows (#3510).

Updates httpx2 from 2.12.0 to 2.13.1

Release notes

Sourced from httpx2's releases.

v2.13.1

Highlights

📤 Accurate file upload lengths

Passing a file as content= now calculates Content-Length from its remaining bytes, respecting the current file position (#1214).

🔐 Reliable proxy TLS and HTTP/2 negotiation

TLS hostname overrides now apply inside HTTP proxy tunnels without affecting the proxy's own TLS connection (#1223). HTTP/2 is advertised first when enabled, and HTTP/1.1 is omitted when disabled (#1155).

🧹 Clean WebSocket shutdown

The sync WebSocket keepalive thread now exits cleanly when a ping races with connection shutdown (#1228).

httpx2

Fixed

• Calculate Content-Length from the remaining bytes when a file is passed as content=, respecting its current position (#1214).
• Stop the sync WebSocket keepalive thread cleanly when a ping races with connection shutdown (#1228).

httpcore2

Fixed

• Honor the sni_hostname extension for TLS inside HTTP proxy tunnels without applying it to the proxy's TLS connection (#1223).
• Prefer HTTP/2 during TLS protocol negotiation when enabled, and stop advertising HTTP/1.1 when it is disabled (#1155).

Full Changelog: pydantic/httpx2@v2.13.0...v2.13.1

v2.13.0

Highlights

🔐 Reliable TLS verification controls

The CLI --no-verify flag now disables TLS certificate verification as intended, and --verify provides an explicit counterpart (pydantic/httpx2#1140, pydantic/httpx2#1186).

🧹 Safer async stream cleanup

Stopping a streamed response early no longer risks a nested async generator finalization error (pydantic/httpx2#1204).

httpx2

Changed

• Require brotlicffi 1.2.0.2 or later for the brotli extra on non-CPython implementations in pydantic/httpx2#1179

Updates ruff from 0.15.15 to 0.17.0

Release notes

Sourced from ruff's releases.

0.17.0

Release Notes

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.

Breaking changes

• Update the default and latest Python versions for 3.15 (#28792)

  Ruff now defaults to Python 3.11 instead of 3.10 when no Python version is configured through target-version or requires-python. When checking for syntax errors without a configured Python version, Ruff now defaults to Python 3.15 instead of 3.14.

• Update the default rule set (#28786)

  Several of the flake8-datetimez rules (DTZ001, DTZ005, DTZ006, DTZ007, DTZ011, DTZ012, and DTZ901) are no longer enabled by default, while undefined-local-with-nested-import-star-usage (F406), which corresponds to a syntax error, is now enabled by default.

• Update Rust crate quick-junit to 0.8.0 (#27295)

  JUnit output now uses a skipped attribute instead of disabled on <testsuite> elements and includes a skipped attribute on the root <testsuites> element.

• [flake8-import-conventions] Add datetime as dt as a conventional alias (ICN001) (#28790)

• Support Unicode dummy variable names (#28722)

  The default lint.dummy-variable-rgx now recognizes underscore-prefixed Unicode names, such as _次, as dummy variables.

• Update to Unicode 17 (#21229, #28784)

  Ruff now uses Unicode 17 data for identifier normalization and named character escapes ("\N{...}").

• Always show unsafe and display-only fixes in the CLI (#27810)

  The default full output format now shows unsafe fixes and suggestions requiring manual review, regardless of the unsafe-fixes setting. Actually applying unsafe fixes still requires explicit opt-in.

• Remove the Python dependency from conda-forge builds (conda-forge/ruff-feedstock#361)

  The conda-forge build no longer depends on Python, now supports linux-riscv64, win-arm64, and linux-ppc64le platforms, and now includes shell completions. However, no longer depending on Python means that python -m ruff and import ruff will no longer work. Use ruff directly from PATH instead. PyPI installations and those from the standalone installer are unaffected.

• Remove support for ruff-lsp (#28750)

  Support for ruff-lsp, the legacy Python language server deprecated in Ruff v0.9.5, has been removed. The Ruff VS Code extension now always uses the native language server; ruff.nativeServer is deprecated and ignored. See the migration guide.

Stabilization

The following rules have been stabilized and are no longer in preview:

• lazy-import-mismatch (TID254)
• lazy-import-immediately-resolved (TID255)
• os-path-commonprefix (RUF071)

Changelog

Sourced from ruff's changelog.

0.17.0

Released on 2026-10-09.

The executables in our macOS and Windows release archives and ruff wheels are now code-signed. macOS executables are signed with an Apple Developer ID certificate and notarized by Apple. Windows executables have timestamped Authenticode signatures from Azure Artifact Signing. This enables verification of the release publisher and binary integrity, supports publisher-based allowlisting, and should reduce security warnings and antivirus false positives.
