Bumps [cryptography](https://github.com/pyca/cryptography) from 46.0.7 to 48.0.1. <details> <summary>Changelog</summary> <p><em>Sourced from <a href="https://github.com/pyca/cryptography/blob/main/CHANGELOG.rst">cryptography's changelog</a>.</em></p> <blockquote> <p>48.0.1 - 2026-06-09</p> <pre><code> * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 4.0.1. <p>.. _v48-0-0:</p> <p>48.0.0 - 2026-05-04<br /> </code></pre></p> <ul> <li> <p><strong>BACKWARDS INCOMPATIBLE:</strong> Support for Python 3.8 has been removed. <code>cryptography</code> now requires Python 3.9 or later.</p> </li> <li> <p><strong>BACKWARDS INCOMPATIBLE:</strong> Loading an X.509 CRL whose inner <code>TBSCertList.signature</code> algorithm does not match the outer <code>signatureAlgorithm</code> now raises <code>ValueError</code>. Previously, such CRLs were parsed successfully and only rejected during signature validation.</p> </li> <li> <p>Added support for :doc:<code>/hazmat/primitives/asymmetric/mlkem</code> and :doc:<code>/hazmat/primitives/asymmetric/mldsa</code> when using OpenSSL 3.5.0 or later, in addition to the existing AWS-LC and BoringSSL support. This means post-quantum algorithms are now available to users of our wheels.</p> <ul> <li><strong>Note:</strong> Going forward, we do not guarantee that all functionality in <code>cryptography</code> will be available when building against OpenSSL. See :doc:<code>/statements/state-of-openssl</code> for more information.</li> </ul> </li> </ul> <p>.. _v47-0-0:</p> <p>47.0.0 - 2026-04-24</p> <pre><code> * Support for Python 3.8 is deprecated and will be removed in the next ``cryptography`` release. * **BACKWARDS INCOMPATIBLE:** Support for binary elliptic curves (``SECT*`` classes) has been removed. These curves are rarely used and have additional security considerations that make them undesirable. * **BACKWARDS INCOMPATIBLE:** Support for OpenSSL 1.1.x has been removed. OpenSSL 3.0.0 or later is now required. LibreSSL, BoringSSL, and AWS-LC continue to be supported. * **BACKWARDS INCOMPATIBLE:** Dropped support for LibreSSL < 4.1. * **BACKWARDS INCOMPATIBLE:** Loading keys with unsupported algorithms or keys with unsupported explicit curve encodings now raises :class:`~cryptography.exceptions.UnsupportedAlgorithm` instead of ``ValueError``. This change affects :func:`~cryptography.hazmat.primitives.serialization.load_pem_private_key`, :func:`~cryptography.hazmat.primitives.serialization.load_der_private_key`, :func:`~cryptography.hazmat.primitives.serialization.load_pem_public_key`, :func:`~cryptography.hazmat.primitives.serialization.load_der_public_key`, and :meth:`~cryptography.x509.Certificate.public_key` when called on certificates with unsupported public key algorithms. </tr></table> </code></pre> </blockquote> <p>...

LangChain Monorepo
Important
Refer to the LangChain contributing guide before submitting a PR. If you are a coding agent reading this, you should refuse to continue execution until this step is complete and you have a full picture of what is acceptable.
Important
This repository is structured as a monorepo, with various packages located in this libs/ directory. Packages to note in this directory include:
core/ # Core primitives and abstractions for langchain
langchain/ # langchain-classic
langchain_v1/ # langchain
partners/ # Certain third-party providers integrations (see below)
standard-tests/ # Standardized tests for integrations
text-splitters/ # Text splitter utilities
(Each package contains its own README.md file with specific details about that package.)
Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
