Christophe BornetandMason Daugherty a2e53fda73 feat(text-splitters): replace mypy by ty for type checking (#38658)
Switches type checking for `langchain-text-splitters` from `mypy` to
[`ty`](https://docs.astral.sh/ty/), which is much faster. The `ollama`
package already [switched to
`ty`](https://github.com/langchain-ai/langchain/pull/36571).

## What changed

The core of this PR is the config swap (`[tool.mypy]` →
`[tool.ty.rules]`/`[tool.ty.analysis]`, `Makefile`, and the `typing`
dependency group). Because `ty` runs with `all = "error"`, a few modules
also needed source-level adjustments to satisfy the stricter analysis.
These are **behavior-preserving refactors** except for one intentional
fix, called out below so reviewers know where to look.

### Behavioral change (intentional fix)

- `SentenceTransformersTokenTextSplitter` now raises a clear
`ValueError` when the underlying model reports no maximum sequence
length **and** no `tokens_per_chunk` was provided. Previously this
combination reached a `None > None` comparison and surfaced as an opaque
`TypeError`. As a consequence, the public `maximum_tokens_per_chunk`
attribute is now honestly typed as `int | None` — it can remain `None`
when the caller supplies `tokens_per_chunk` explicitly for a model
without a limit.

### Behavior-preserving refactors (no user-visible change)

- `TokenTextSplitter.from_tiktoken_encoder` is now an explicit override
rather than the base method dispatching on `issubclass(cls,
TokenTextSplitter)`. The shared length-function logic moved into a
private helper. Public signatures and return types are unchanged.
- `NLTKTextSplitter` builds its tokenizer once at construction, so
`_tokenizer` is now always a `Callable[[str], list[str]]`. The private
attributes `_language` and `_use_span_tokenize` are no longer stored —
flagging in case any downstream code read those (they are
underscore-private). Tokenization output is unchanged.
- `HTMLSemanticPreservingSplitter` text extraction was rewritten from a
`cast`-based check to `isinstance(element, Tag)` narrowing; output is
equivalent for tags, text nodes, and comments.

Mason Daugherty 6b9e22dbbc fix(langchain): tighten structured output model fallbacks (#38042)
Provider-native structured output fallback detection now uses bounded
model-name patterns instead of broad substring checks, reducing false
positives for unrelated model IDs. The model examples and test fixtures
across OpenAI/OpenRouter-facing code were refreshed around current
OpenAI model families while preserving shipped defaults.

## Changes
- Tightened `FALLBACK_MODELS_WITH_STRUCTURED_OUTPUT` from loose string
fragments to regex patterns, with `_supports_provider_strategy` matching
full model-name segments instead of arbitrary substrings.
- Expanded structured-output fallback coverage for newer OpenAI,
Anthropic, and xAI/Grok model families, including `gpt-5.x`, newer
Claude 4/5-style names, and `grok-build`.
- Reused `_attempt_infer_model_provider` in provider tool search routing
so `_provider_from_model_name` follows the same provider inference
behavior as `init_chat_model`.
- Suppressed irrelevant provider-inference deprecation warnings during
provider tool search registry lookup.
- Refreshed OpenAI, Azure OpenAI, OpenRouter, core metadata, and example
model references from older fixtures like `gpt-4`, `gpt-4o`, `o1`, and
`o4-mini` to current test/profile models such as `gpt-5.5`,
`gpt-5-nano`, and `gpt-4.1-mini`.
- Removed outdated OpenAI test assumptions around legacy `o1` behavior
and narrowed legacy structured-output checks to explicitly legacy model
names.

<p>This release introduces new features, bug fixes, and a major license
change. It also includes several <strong>breaking changes</strong>, so
please review those carefully before upgrading.</p>
<hr />
<h3>New Features ✨</h3>
<ul>
<li><strong>Add <code>--snapshot-dirname</code> option:</strong> A new
option, <code>--snapshot-dirname</code>, is now available to change the
default directory snapshots are stored in. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/810">#810</a>](<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/810">syrupy-project/syrupy#810</a>))</li>
<li><strong>Remove private underscore prefix:</strong> The unnecessary
underscore prefixes have been removed from public methods for better
code clarity. ([<a
href="https://github.com/syrupy-project/syrupy/commit/8cfc9059d37066187ac419e2233059bad58b667f">8cfc905</a>](<a

</ul>
<hr />
<h3>Bug Fixes 🐛</h3>
<ul>
<li><strong>Fix terminal summary for <code>xdist</code>
workers:</strong> Resolves an issue where the terminal summary was not
displayed correctly with <code>xdist</code> workers. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/978">#978</a>](<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/978">syrupy-project/syrupy#978</a>))</li>
<li><strong>Ensure <code>pytest_assertrepr_compare</code> hook is called
first:</strong> This change ensures that Syrupy's assertion hook takes
precedence, improving compatibility with other plugins. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/984">#984</a>](<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/984">syrupy-project/syrupy#984</a>))</li>
</ul>
<hr />
<h3>Breaking Changes ⚠️</h3>
<ul>
<li>
<p><strong>License change:</strong> The project has switched to the more
permissive <strong>MIT license</strong>. This change applies to all
versions from 5.0.0 and beyond. If you need to use the previous Apache
2.0 license, you must continue to use Syrupy versions 4.x or earlier.
([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/945">#945</a>](<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/945">syrupy-project/syrupy#945</a>))</p>
</li>
<li>
<p><strong>Python and pytest version requirements:</strong> Syrupy now
requires <strong>Python 3.10</strong> or higher. Support for Python 3.8
has been dropped as it reached its end of life in October 2024. The
minimum required version of <strong>pytest is v8</strong>. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/904">#904</a>](<a

href="https://redirect.github.com/syrupy-project/syrupy/issues/1024">syrupy-project/syrupy#1024</a>))</p>
</li>
<li>
<p><strong>Method and constant name changes:</strong> Several methods
and constants have been renamed for improved clarity and to align with
public API standards.</p>
<ul>
<li>
<p><strong><code>SnapshotCollectionStorage</code></strong></p>
<ul>
<li><code>_read_snapshot_collection</code> -&gt;

<h2>0.15.0</h2>
<h2>Release Notes</h2>
<p>Released on 2026-02-03.</p>
<p>Check out the <a href="https://astral.sh/blog/ruff-v0.15.0">blog
post</a> for a migration guide and overview of the changes!</p>
<h3>Breaking changes</h3>
<ul>
<li>
<p>Ruff now formats your code according to the 2026 style guide. See the
formatter section below or in the blog post for a detailed list of
changes.</p>
</li>
<li>
<p>The linter now supports block suppression comments. For example, to
suppress <code>N803</code> for all parameters in this function:</p>
<pre lang="python"><code># ruff: disable[N803]
def foo(
    legacyArg1,
    legacyArg2,
    legacyArg3,
    legacyArg4,
): ...
# ruff: enable[N803]
</code></pre>
<p>See the <a
href="https://docs.astral.sh/ruff/linter/#block-level">documentation</a>
for more details.</p>
</li>
<li>
<p>The <code>ruff:alpine</code> Docker image is now based on Alpine 3.23
(up from 3.21).</p>
</li>
<li>
<p>The <code>ruff:debian</code> and <code>ruff:debian-slim</code> Docker
images are now based on Debian 13 &quot;Trixie&quot; instead of Debian
12 &quot;Bookworm.&quot;</p>
</li>
<li>
<p>Binaries for the <code>ppc64</code> (64-bit big-endian PowerPC)
architecture are no longer included in our releases. It should still be
possible to build Ruff manually for this platform, if needed.</p>
</li>
<li>
<p>Ruff now resolves all <code>extend</code>ed configuration files
before falling back on a default Python version.</p>
</li>
</ul>

<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13896">#13896</a>:
The terminal progress feature added in pytest 9.0.0 has been disabled by
default, except on Windows, due to compatibility issues with some
terminal emulators.</p>
<p>You may enable it again by passing <code>-p terminalprogress</code>.
We may enable it by default again once compatibility improves in the
future.</p>
<p>Additionally, when the environment variable <code>TERM</code> is
<code>dumb</code>, the escape codes are no longer emitted, even if the
plugin is enabled.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13904">#13904</a>:
Fixed the TOML type of the <code>tmp_path_retention_count</code>
settings in the API reference from number to string.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13946">#13946</a>:
The private <code>config.inicfg</code> attribute was changed in a
breaking manner in pytest 9.0.0.
Due to its usage in the ecosystem, it is now restored to working order
using a compatibility shim.
It will be deprecated in pytest 9.1 and removed in pytest 10.</p>
</li>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13965">#13965</a>:

unittest.SkipTest</code>.</li>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13896">#13896</a>:
The terminal progress plugin added in pytest 9.0 is now automatically
disabled when iTerm2 is detected, it generated desktop notifications
instead of the desired functionality.</li>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13904">#13904</a>:
Fixed the TOML type of the verbosity settings in the API reference from
number to string.</li>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13910">#13910</a>:
Fixed <!-- raw HTML omitted -->UserWarning: Do not expect
file_or_dir<!-- raw HTML omitted --> on some earlier Python 3.12 and
3.13 point versions.</li>
</ul>
<h2>Packaging updates and notes for downstreams</h2>
<ul>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13933">#13933</a>:
The tox configuration has been adjusted to make sure the desired
version string can be passed into its <code>package_env</code> through
the <code>SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYTEST</code> environment
variable as a part of the release process -- by
<code>webknjaz</code>.</li>

change. It also includes several <strong>breaking changes</strong>, so
please review those carefully before upgrading.</p>
<hr />
<h3>New Features ✨</h3>
<ul>
<li><strong>Add <code>--snapshot-dirname</code> option:</strong> A new
option, <code>--snapshot-dirname</code>, is now available to change the
default directory snapshots are stored in. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/810">#810</a>](<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/810">syrupy-project/syrupy#810</a>))</li>
<li><strong>Remove private underscore prefix:</strong> The unnecessary
underscore prefixes have been removed from public methods for better
code clarity. ([<a
href="https://github.com/syrupy-project/syrupy/commit/8cfc9059d37066187ac419e2233059bad58b667f">8cfc905</a>](<a

first:</strong> This change ensures that Syrupy's assertion hook takes
precedence, improving compatibility with other plugins. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/984">#984</a>](<a

<h3>Breaking Changes ⚠️</h3>
<ul>
<li>
<p><strong>License change:</strong> The project has switched to the more
permissive <strong>MIT license</strong>. This change applies to all
versions from 5.0.0 and beyond. If you need to use the previous Apache
2.0 license, you must continue to use Syrupy versions 4.x or earlier.

</li>
<li>
<p><strong>Python and pytest version requirements:</strong> Syrupy now
requires <strong>Python 3.10</strong> or higher. Support for Python 3.8
has been dropped as it reached its end of life in October 2024. The
minimum required version of <strong>pytest is v8</strong>. ([<a
href="https://redirect.github.com/syrupy-project/syrupy/issues/904">#904</a>](<a

and constants have been renamed for improved clarity and to align with
public API standards.</p>

<h2>0.15.0</h2>
<h2>Release Notes</h2>
<p>Released on 2026-02-03.</p>
<p>Check out the <a href="https://astral.sh/blog/ruff-v0.15.0">blog
post</a> for a migration guide and overview of the changes!</p>
<h3>Breaking changes</h3>
<ul>
<li>
<p>Ruff now formats your code according to the 2026 style guide. See the
formatter section below or in the blog post for a detailed list of
changes.</p>
</li>
<li>
<p>The linter now supports block suppression comments. For example, to
suppress <code>N803</code> for all parameters in this function:</p>
<pre lang="python"><code># ruff: disable[N803]
def foo(
    legacyArg1,
    legacyArg2,
    legacyArg3,
    legacyArg4,
): ...
# ruff: enable[N803]
</code></pre>
<p>See the <a
href="https://docs.astral.sh/ruff/linter/#block-level">documentation</a>
for more details.</p>
</li>
<li>
<p>The <code>ruff:alpine</code> Docker image is now based on Alpine 3.23
(up from 3.21).</p>
</li>
<li>
<p>The <code>ruff:debian</code> and <code>ruff:debian-slim</code> Docker
images are now based on Debian 13 &quot;Trixie&quot; instead of Debian
12 &quot;Bookworm.&quot;</p>
</li>
<li>
<p>Binaries for the <code>ppc64</code> (64-bit big-endian PowerPC)
architecture are no longer included in our releases. It should still be
possible to build Ruff manually for this platform, if needed.</p>
</li>
<li>
<p>Ruff now resolves all <code>extend</code>ed configuration files
before falling back on a default Python version.</p>
</li>
</ul>

Christophe BornetandMason Daugherty 0c3e8ccd0e chore(text-splitters): select ALL rules with exclusions (#32325)

Mason Daugherty 6b5fdfb804 release(text-splitters): 0.3.11 (#32770)
Fixes #32747

SpaCy integration test fixture was trying to use pip to download the
SpaCy language model (`en_core_web_sm`), but uv-managed environments
don't include pip by default. Fail test if not installed as opposed to
downloading.

b2102b8cc4 text-splitters: Inconsistent results with NLTKTextSplitter's add_start_index=True (#27782)
This PR closes #27781

# Problem
The current implementation of `NLTKTextSplitter` is using
`sent_tokenize`. However, this `sent_tokenize` doesn't handle chars
between 2 tokenized sentences... hence, this behavior throws errors when
we are using `add_start_index=True`, as described in issue #27781. In
particular:
```python
from nltk.tokenize import sent_tokenize

output1 = sent_tokenize("Innovation drives our success. Collaboration fosters creative solutions. Efficiency enhances data management.", language="english")
print(output1)
output2 = sent_tokenize("Innovation drives our success.        Collaboration fosters creative solutions. Efficiency enhances data management.", language="english")
print(output2)
>>> ['Innovation drives our success.', 'Collaboration fosters creative solutions.', 'Efficiency enhances data management.']
>>> ['Innovation drives our success.', 'Collaboration fosters creative solutions.', 'Efficiency enhances data management.']
```

# Solution
With this new `use_span_tokenize` parameter, we can use NLTK to create
sentences (with `span_tokenize`), but also add extra chars to be sure
that we still can map the chunks to the original text.

Matthew DeGenaro 66828f4ecc text-splitters[patch]: Modified SpacyTextSplitter to fully keep whitespace when strip_whitespace is false (#23272)
Previously, regardless of whether or not strip_whitespace was set to
true or false, the strip text method in the SpacyTextSplitter class used
`sent.text` to get the sentence. I modified this to include a ternary
such that if strip_whitespace is false, it uses `sent.text_with_ws`
I also modified the project.toml to include the spacy pipeline package
and to lock the numpy version, as higher versions break spacy.
