<h2>4.0.0 (2026-09-28):</h2>
<p>OAuth2.0 Provider:</p>
<ul>
<li><strong>Breaking</strong>: <a
href="https://redirect.github.com/oauthlib/oauthlib/issues/951">#951</a>:
Removed JSONP support from token revocation endpoint.
JSONP has been superseded by CORS for cross-origin requests.
The <code>enable_jsonp</code> parameter has been removed from
<code>RevocationEndpoint</code>
and the <code>callback</code> parameter has been removed from
<code>prepare_token_revocation_request</code>.</li>
<li><strong>Breaking</strong>: <a
href="https://redirect.github.com/oauthlib/oauthlib/issues/919">#919</a>,
<a
href="https://redirect.github.com/oauthlib/oauthlib/issues/920">#920</a>:
Fixed <code>DeviceCodeGrant.validate_token_request</code>
trying to authenticate public clients.
Client authentication validation has been reorganized and is now shared
across <code>AuthorizationCodeGrant</code>,
<code>DeviceCodeGrant</code>, <code>RefreshTokenGrant</code>
and <code>ResourceOwnerPasswordCredentialsGrant</code>: the
<code>grant_type</code> parameter
is validated before client authentication, so requests missing
<code>grant_type</code> now return <code>400 invalid_request</code>
instead of
<code>401 invalid_client</code>.</li>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/963">#963</a>:
Improved PKCE code comparison</li>
</ul>
<p>Misc:</p>
<ul>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/904">#904</a>:
Stop installing <code>examples</code> into
<code>site-packages</code>.</li>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/930">#930</a>:
Add devcontainer, Add Python3.14, Python3.14t.</li>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/931">#931</a>:
Fix ruff checks about unused variables.</li>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/932">#932</a>:
Dropped EOL Python 3.8 from CI.</li>
<li><a
href="https://redirect.github.com/oauthlib/oauthlib/issues/934">#934</a>:

<li><a

(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.
