<h2>Bug fixes</h2>
<ul>
<li>
<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>:
Fixed quadratic-time behavior when handling <code>unittest</code>
subtests in Python 3.10.</p>

</ul>
<h2>Improved documentation</h2>
<ul>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/4492">#4492</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>
</ul>

<h2>v5.0.0</h2>
<h2>Syrupy 5.0.0</h2>
<p><em>(2025-09-28)</em></p>
<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="8cfc9059d3">8cfc905</a>](<a
href="8cfc9059d3</a>))</li>
</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">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/904">syrupy-project/syrupy#904</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> ->
<code>read_snapshot_collection</code></li>
<li><code>_read_snapshot_data_from_location</code> ->
<code>read_snapshot_data_from_location</code></li>
<li><code>_write_snapshot_collection</code> ->

<li><code>_get_file_basename</code> ->
<code>get_file_basename</code></li>
<li><code>_file_extension</code> -> <code>file_extension</code></li>
</ul>

<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/astral-sh/ruff/releases">ruff's
releases</a>.</em></p>
<blockquote>
<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 "Trixie" instead of Debian
12 "Bookworm."</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>
<h3>Stabilization</h3>

preview:</p>

<h2>9.0.2</h2>
<h1>pytest 9.0.2 (2025-12-06)</h1>
<h2>Bug fixes</h2>
<ul>
<li>
<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>:
Fixed quadratic-time behavior when handling <code>unittest</code>
subtests in Python 3.10.</p>
</li>
</ul>
<h2>Improved documentation</h2>
<ul>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/4492">#4492</a>:
The API Reference now contains cross-reference-able documentation of
<code>pytest's command-line flags
<command-line-flags></code>.</li>
</ul>
<h2>9.0.1</h2>
<h1>pytest 9.0.1 (2025-11-12)</h1>
<h2>Bug fixes</h2>
<ul>
<li><a
href="https://redirect.github.com/pytest-dev/pytest/issues/13895">#13895</a>:
Restore support for skipping tests via <code>raise
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>
</ul>
<h2>Contributor-facing changes</h2>
<ul>
<li><a

<a
href="https://redirect.github.com/pytest-dev/pytest/issues/13942">#13942</a>:
The CI/CD part of the release automation is now capable of
creating GitHub Releases without having a Git checkout on

<h2>v5.0.0</h2>
<h2>Syrupy 5.0.0</h2>
<p><em>(2025-09-28)</em></p>
<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="8cfc9059d3">8cfc905</a>](<a
href="8cfc9059d3</a>))</li>
</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

</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

</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> ->

<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 "Trixie" instead of Debian
12 "Bookworm."</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>

`pyproject.toml` files (even optional ones) unless you have explicit
permission to do so by a maintainer.
Summary
Fixes an issue where HTMLSemanticPreservingSplitter failed to preserve
elements nested inside non-container tags. With these changes, preserved
elements are now correctly detected and handled at any nesting depth.
Root Cause
`_process_element()` only recursed into a small set of hard-coded
container tags (`html`, `body`, `div`, `main`). For other tags, the
subtree was flattened into text, preventing nested preserved elements
(inside `<p>`, `<section>`, `<article>`, etc.) from being detected.
Fix
- Updated traversal logic in _process_element (html.py) to recursively
process child elements for any tag that contains nested elements
- Avoided duplicate text extraction
- Preserved correct placeholder ordering
- Treated leaf nodes as text only
Tests
Adds regression tests covering preserved elements nested inside
non-container tags, including:
- table inside section
- nested divs
- code inside paragraph
All existing tests pass (make lint, format, test, etc).
Breaking changes
None.
Fixes
Fixes#31569
Disclaimer
GitHub Copilot was used to assist with test case design in
test_text_splitters.py and documentation comments; all code logic was
manually implemented and reviewed.

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.
## Description
This PR adds support for custom header patterns in
`MarkdownHeaderTextSplitter`, allowing users to define non-standard
Markdown header formats (like `**Header**`) and specify their hierarchy
levels.
**Issue:** Fixes#22738
**Dependencies:** None - this change has no new dependencies
**Key Changes:**
- Added optional `custom_header_patterns` parameter to support
non-standard header formats
- Enable splitting on patterns like `**Header**` and `***Header***`
- Maintain full backward compatibility with existing usage
- Added comprehensive tests for custom and mixed header scenarios
## Example Usage
```python
from langchain_text_splitters import MarkdownHeaderTextSplitter
headers_to_split_on = [
("**", "Chapter"),
("***", "Section"),
]
custom_header_patterns = {
"**": 1, # Level 1 headers
"***": 2, # Level 2 headers
}
splitter = MarkdownHeaderTextSplitter(
headers_to_split_on=headers_to_split_on,
custom_header_patterns=custom_header_patterns,
)
# Now **Chapter 1** is treated as a level 1 header
# And ***Section 1.1*** is treated as a level 2 header
```
## Testing
- ✅ Added unit tests for custom header patterns
- ✅ Added tests for mixed standard and custom headers
- ✅ All existing tests pass (backward compatibility maintained)
- ✅ Linting and formatting checks pass
---
The implementation provides a flexible solution while maintaining the
simplicity of the existing API. Users can continue using the splitter
exactly as before, with the new functionality being entirely opt-in
through the `custom_header_patterns` parameter.

## Summary
- Removes the `xslt_path` parameter from HTMLSectionSplitter to
eliminate XXE attack vector
- Hardens XML/HTML parsers with secure configurations to prevent XXE
attacks
- Adds comprehensive security tests to ensure the vulnerability is fixed
## Context
This PR addresses a critical XXE vulnerability discovered in the
HTMLSectionSplitter component. The vulnerability allowed attackers to:
- Read sensitive local files (SSH keys, passwords, configuration files)
- Perform Server-Side Request Forgery (SSRF) attacks
- Exfiltrate data to attacker-controlled servers
## Changes Made
1. **Removed `xslt_path` parameter** - This eliminates the primary
attack vector where users could supply malicious XSLT files
2. **Hardened XML parsers** - Added security configurations to prevent
XXE attacks even with the default XSLT:
- `no_network=True` - Blocks network access
- `resolve_entities=False` - Prevents entity expansion -
`load_dtd=False` - Disables DTD processing -
`XSLTAccessControl.DENY_ALL` - Blocks all file/network I/O in XSLT
transformations
3. **Added security tests** - New test file `test_html_security.py` with
comprehensive tests for various XXE attack vectors
4. **Updated existing tests** - Modified tests that were using the
removed `xslt_path` parameter
## Test Plan
- [x] All existing tests pass
- [x] New security tests verify XXE attacks are blocked
- [x] Code passes linting and formatting checks
- [x] Tested with both old and new versions of lxml

**Description:**
Previously, when transitioning from a deeper Markdown header (e.g., ###)
to a shallower one (e.g., ##), the
ExperimentalMarkdownSyntaxTextSplitter retained the deeper header in the
metadata.
This commit updates the `_resolve_header_stack` method to remove headers
at the same or deeper levels before appending the current header. As a
result, each chunk now reflects only the active header context.
Fixes unexpected metadata leakage across sections in nested Markdown
documents.
Additionally, test cases have been updated to:
- Validate correct header resolution and metadata assignment.
- Cover edge cases with nested headers and horizontal rules.

### Description
Add keep_separator arg to HTMLSemanticPreservingSplitter and pass value
to instance of RecursiveCharacterTextSplitter used under the hood.
### Issue
Documents returned by `HTMLSemanticPreservingSplitter.split_text(text)`
are defaulted to use separators at beginning of page_content. [See third
and fourth document in example output from how-to
guide](https://python.langchain.com/docs/how_to/split_html/#using-htmlsemanticpreservingsplitter):
```
[Document(metadata={'Header 1': 'Main Title'}, page_content='This is an introductory paragraph with some basic content.'),
Document(metadata={'Header 2': 'Section 1: Introduction'}, page_content='This section introduces the topic'),
Document(metadata={'Header 2': 'Section 1: Introduction'}, page_content='. Below is a list: First item Second item Third item with bold text and a link Subsection 1.1: Details This subsection provides additional details'),
Document(metadata={'Header 2': 'Section 1: Introduction'}, page_content=". Here's a table: Header 1 Header 2 Header 3 Row 1, Cell 1 Row 1, Cell 2 Row 1, Cell 3 Row 2, Cell 1 Row 2, Cell 2 Row 2, Cell 3"),
Document(metadata={'Header 2': 'Section 2: Media Content'}, page_content='This section contains an image and a video:  '),

## Description
This pull request introduces a new text splitter,
`JSFrameworkTextSplitter`, to the Langchain library. The
`JSFrameworkTextSplitter` extends the `RecursiveCharacterTextSplitter`
to handle JavaScript framework code effectively, including React (JSX),
Vue, and Svelte. It identifies and utilizes framework-specific component
tags and syntax elements as splitting points, alongside standard
JavaScript syntax. This ensures that code is divided at natural
boundaries, enhancing the parsing and processing of JavaScript and
framework-specific code.
### Key Features
- Supports React (JSX), Vue, and Svelte frameworks.
- Identifies and uses framework-specific tags and syntax elements as
natural splitting points.
- Extends the existing `RecursiveCharacterTextSplitter` for seamless
integration.
## Issue
No specific issue addressed.
## Dependencies
No additional dependencies required.

This pull request updates the `HTMLHeaderTextSplitter` by replacing the
`split_text_from_file` method's implementation. The original method used
`lxml` and XSLT for processing HTML files, which caused
`lxml.etree.xsltapplyerror maxhead` when handling large HTML documents
due to limitations in the XSLT processor. Fixes#13149
By switching to BeautifulSoup (`bs4`), we achieve:
- **Improved Performance and Reliability:** BeautifulSoup efficiently
processes large HTML files without the errors associated with `lxml` and
XSLT.
- **Simplified Dependencies:** Removes the dependency on `lxml` and
external XSLT files, relying instead on the widely used `beautifulsoup4`
library.
- **Maintained Functionality:** The new method replicates the original
behavior, ensuring compatibility with existing code and preserving the
extraction of content and metadata.
**Issue:**
This change addresses issues related to processing large HTML files with
the existing `HTMLHeaderTextSplitter` implementation. It resolves
problems where users encounter lxml.etree.xsltapplyerror maxhead due to
large HTML documents.
**Dependencies:**
- **BeautifulSoup (`beautifulsoup4`):** The `beautifulsoup4` library is
now used for parsing HTML content.
- Installation: `pip install beautifulsoup4`
**Code Changes:**
Updated the `split_text_from_file` method in `HTMLHeaderTextSplitter` as
follows:
```python
def split_text_from_file(self, file: Any) -> List[Document]:
"""Split HTML file using BeautifulSoup.

**Description:**
With current HTML splitters, they rely on secondary use of the
`RecursiveCharacterSplitter` to further chunk the document into
manageable chunks. The issue with this is it fails to maintain important
structures such as tables, lists, etc within HTML.
This Implementation of a HTML splitter, allows the user to define a
maximum chunk size, HTML elements to preserve in full, options to
preserve `<a>` href links in the output and custom handlers.
The core splitting begins with headers, similar to `HTMLHeaderSplitter`.
If these sections exceed the length of the `max_chunk_size` further
recursive splitting is triggered. During this splitting, elements listed
to preserve, will be excluded from the splitting process. This can cause
chunks to be slightly larger then the max size, depending on preserved
length. However, all contextual relevance of the preserved item remains
intact.
**Custom Handlers**: Sometimes, companies such as Atlassian have custom
HTML elements, that are not parsed by default with `BeautifulSoup`.
Custom handlers allows a user to provide a function to be ran whenever a
specific html tag is encountered. This allows the user to preserve and
gather information within custom html tags that `bs4` will potentially
miss during extraction.
**Dependencies:** User will need to install `bs4` in their project to
utilise this class
I have also added in `how_to` and unit tests, which require `bs4` to
run, otherwise they will be skipped.

- **Description:**
This PR resolves an issue with the
`ExperimentalMarkdownSyntaxTextSplitter` class, which retains the
internal state across multiple calls to the `split_text` method. This
behaviour caused an unintended accumulation of chunks in `self`
variables, leading to incorrect outputs when processing multiple
Markdown files sequentially.
- Modified `libs\text-splitters\langchain_text_splitters\markdown.py` to
reset the relevant internal attributes at the start of each `split_text`
invocation. This ensures each call processes the input independently.
- Added unit tests in
`libs\text-splitters\tests\unit_tests\test_text_splitters.py` to verify
the fix and ensure the state does not persist across calls.
- **Issue:**
Fixes [#26440](https://github.com/langchain-ai/langchain/issues/26440).
- **Dependencies:**
No additional dependencies are introduced with this change.
- [x] Unit tests were added to verify the changes.
- [x] Updated documentation where necessary.
- [x] Ran `make format`, `make lint`, and `make test` to ensure

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.

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.

Thank you for contributing to LangChain!
**Description:** Noticed an issue with when I was calling
`RecursiveJsonSplitter().split_json()` multiple times that I was getting
weird results. I found an issue where `chunks` list in the `_json_split`
method. If chunks is not provided when _json_split (which is the case
when split_json calls _json_split) then the same list is used for
subsequent calls to `_json_split`.
You can see this in the test case i also added to this commit.
Output should be:
```
[{'a': 1, 'b': 2}]
[{'c': 3, 'd': 4}]
```
Instead you get:
```
[{'a': 1, 'b': 2}]
[{'a': 1, 'b': 2, 'c': 3, 'd': 4}]
```

#### Description
This MR defines a `ExperimentalMarkdownSyntaxTextSplitter` class. The
main goal is to replicate the functionality of the original
`MarkdownHeaderTextSplitter` which extracts the header stack as metadata
but with one critical difference: it keeps the whitespace of the
original text intact.
This draft reimplements the `MarkdownHeaderTextSplitter` with a very
different algorithmic approach. Instead of marking up each line of the
text individually and aggregating them back together into chunks, this
method builds each chunk sequentially and applies the metadata to each
chunk. This makes the implementation simpler. However, since it's
designed to keep white space intact its not a full drop in replacement
for the original. Since it is a radical implementation change to the
original code and I would like to get feedback to see if this is a
worthwhile replacement, should be it's own class, or is not a good idea
at all.
Note: I implemented the `return_each_line` parameter but I don't think
it's a necessary feature. I'd prefer to remove it.
This implementation also adds the following additional features:
- Splits out code blocks and includes the language in the `"Code"`
metadata key
- Splits text on the horizontal rule `---` as well
- The `headers_to_split_on` parameter is now optional - with sensible
defaults that can be overridden.
#### Issue
Keeping the whitespace keeps the paragraphs structure and the formatting
of the code blocks intact which allows the caller much more flexibility
in how they want to further split the individuals sections of the
resulting documents. This addresses the issues brought up by the
community in the following issues:
- https://github.com/langchain-ai/langchain/issues/20823
- https://github.com/langchain-ai/langchain/issues/19436

Update former pull request:
https://github.com/langchain-ai/langchain/pull/22654.
Modified `langchain_text_splitters.HTMLSectionSplitter`, where in the
latest version `dict` data structure is used to store sections from a
html document, in function `split_html_by_headers`. The header/section
element names serve as dict keys. This can be a problem when duplicate
header/section element names are present in a single html document.
Latter ones can replace former ones with the same name. Therefore some
contents can be miss after html text splitting is conducted.
Using a list to store sections can hopefully solve the problem. A Unit
test considering duplicate header names has been added.

## Description
This PR allows passing the HTMLSectionSplitter paths to xslt files. It
does so by fixing two trivial bugs with how passed paths were being
handled. It also changes the default value of the param `xslt_path` to
`None` so the special case where the file was part of the langchain
package could be handled.
## Issue
#22175
**Description:** Added extra functionality to `CharacterTextSplitter`,
`TextSplitter` classes.
The user can select whether to append the separator to the previous
chunk with `keep_separator='end' ` or else prepend to the next chunk.
Previous functionality prepended by default to next chunk.
