Updates haystack-ai from 2.20.0 to 3.3.0

Release notes

Sourced from haystack-ai's releases.

v3.3.0

⭐️ Highlight

⚡️ Faster SentenceWindowRetriever

SentenceWindowRetriever now queries the Document Store once per run or run_async call instead of once per retrieved document. Fewer calls mean lower latency and less load on the Document Store and outputs have not changed, so existing pipelines get faster without code changes.

⬆️ Upgrade Notes

• InMemoryDocumentStore.bm25_retrieval and InMemoryBM25Retriever with BM25L (the default) or BM25Plus now return only documents that contain at least one query term, with or without scale_score. Previously, documents without any query term were returned with a positive score and filled up top_k. As a result, retrieval can now return fewer than top_k documents, or none at all. The delta lower bound now applies only to query terms that occur in the document, as in the original BM25L/BM25+ definitions. So scores of matching documents are lower than before whenever the query has terms that a document does not contain. If you filter results with a fixed score threshold, re-check the threshold. BM25Okapi is not affected.

⚡️ Enhancement Notes

• TextCleaner.run now raises a clear TypeError when texts is not a list or any element is not a str, instead of failing later or producing unexpected results.

🔒 Security Notes

• Haystack now requires anyio>=4.14.2. anyio is installed transitively through httpx and openai; versions before 4.14.2 are affected by CVE-2026-63374 (GHSA-82r6-8w77-94w6).

🐛 Bug Fixes

• Fixed BM25 tokenization in InMemoryDocumentStore for Chinese, Japanese and Korean text. The default bm25_tokenization_regex now splits CJK characters into one token each, so bare-term queries can match words inside longer unspaced runs. Text is also NFC-normalized before tokenization, so composed and decomposed spellings produce the same tokens.

• Fix Pipeline.connect() raising TypeError: object of type 'ellipsis' has no len() when one of the sockets is annotated with Callable[..., T]. A Callable[..., T] now matches callables with any parameters, in both directions, as long as the return types are compatible.

• Fixed ChatPromptBuilder dropping content parts when the template is a list of ChatMessage objects. Only the first TextContent part was rendered, and every other part - additional texts, images, files -was removed from the rendered prompt without a warning. Template variables used in those dropped parts were not detected either, so they were not exposed as inputs. Now all TextContent parts are rendered and the remaining content parts are passed through unchanged.

• Fixed CompactionHook.close() and close_async() to release the token counter's resources as well as the compactor's. Previously, resources such as OpenAITokenCounter's HTTP client remained open after the hook or Agent was closed.

• ConfirmationHook no longer drops the messages that come after the last user or tool message when it rewrites the conversation, such as a system message added by another hook or an assistant answer followed by an on_exit reminder. Before, those messages were removed from the history the Agent sends to the model.

• DocumentToImageContent no longer raises a KeyError for the whole batch when a document points to a PDF page that cannot be converted, because the page is out of range or the PDF cannot be read. That document now gets None in image_contents, like other invalid documents, and the rest of the batch is still converted. The logged warnings now include the path of the PDF file.

• Fixed DOCXToDocument breaking a Markdown table when a cell contains a pipe or spans several paragraphs. A pipe was emitted as a column separator, and a cell's line break ended the row in the middle of it. Pipes are now escaped and line breaks inside a cell are collapsed to a space. The csv table format is unchanged: it already kept such cells intact by quoting them.

• Fixed DOCXToDocument dropping hyperlink addresses inside tables. With link_format set to markdown or plain, links in table cells were written as their display text only, while links in body paragraphs kept their address. Links in table cells are now formatted the same way, in both the markdown and csv table formats. The default link_format="none" output is unchanged.

• Fixed ConditionalRouter.from_dict mutating the caller's routes data in place: serialized output_type strings were deserialized directly inside the caller's dictionaries, so reusing the same serialized pipeline dict afterwards yielded already-deserialized type objects. from_dict now works on a copy and the caller's data is left untouched. BranchJoiner.from_dict received the same treatment.

• LinkContentFetcher no longer adds its timeout and follow_redirects defaults to the client_kwargs dictionary passed by the caller. The dictionary is now copied before the defaults are applied, so reusing one HTTP client configuration across components no longer leaks these defaults.

• Fix MetaFieldRanker to return no documents when missing_meta="drop" and all documents lack the ranking field or have a None value.

• MetaFieldRanker now treats a Document whose meta_field value is None the same as a Document that is missing the field, applying the missing_meta setting to it. Previously a single None value made sorting fail, so the ranker logged a warning and returned all Documents in their original order, ignoring missing_meta="drop" as well.

• MockTextEmbedder and MockDocumentEmbedder now accept non-positive dimension values when embedding or embedding_fn is provided, matching the documented behavior. The default deterministic embedding mode still requires a positive dimension.

• ChatMessage.from_openai_dict_format now accepts tool-call arguments that are already a dictionary instead of raising a TypeError. Some OpenAI-compatible servers send a parsed object rather than a JSON string.

• MetaFieldGroupingRanker now treats a group_by or subgroup_by value of None as missing, the same way it already treats sort_docs_by. Documents with None go to the end with the other ungrouped documents, instead of forming a group named "None" that also absorbed documents whose value was the string "None".

Updates pytest from 8.4.2 to 9.1.1

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.

Updates ruff from 0.16.7 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)

Mypy Release Notes

Next Release

Mypy 2.4

We've just uploaded mypy 2.4.0 to the Python Package Index (PyPI). Mypy is a static type checker for Python. This release includes new features, performance improvements and bug fixes. You can install it as follows:

python3 -m pip install -U mypy

You can read the full documentation for this release on Read the Docs.

Python 3.15 Support

Mypy 2.4 supports running on Python 3.15 and type checking most Python 3.15 features. This includes the new builtin sentinel type for sentinel values (PEP 661), which mypy now supports (see below for details). Lazy imports (PEP 810) and unpacking in comprehensions (PEP 798) are also supported. Closed TypedDicts (PEP 728) have been supported since mypy 2.2, but the extra_items TypedDict argument, also introduced in PEP 728, is still unsupported. Support for extra_items will be added in a future mypy release.

Native Parser Enabled by Default

Mypy now uses the new native parser by default. It's based on the Ruff parser, and it's significantly faster than the legacy parser, which uses the stdlib ast module. The native parser also has other benefits:

• You can target newer Python versions and use recent Python syntax even when running mypy on an older Python version. For example, you can use --python-version 3.15 when running mypy on Python 3.14.
• Stub files can use syntax that is newer than the target Python version. For example, stubs can use the PEP 695 generic class syntax (class Box[T]: ...) when running on or targeting Python 3.10.
• Parallel type checking requires the native parser.

The legacy parser is still available through --no-native-parser, or native_parser = False in the config file (native_parser = false under [tool.mypy] in pyproject.toml). We are planning to remove the legacy parser in early 2027. If you run into a problem with the native parser, please report it on the issue tracker.

Unlike the legacy parser, the native parser doesn't support type comments for variables defined by for and with statements. These type comments are silently ignored, and the types of the variables are
