I'm thrilled to announce the first release candidate for Starlette 1.0.</p> <p>Starlette was created in June 2018 by Tom Christie, and has been on ZeroVer for years. Today, it's downloaded almost <a href="https://pypistats.org/packages/starlette">10 million times a day</a>, serves as the foundation for FastAPI, and has inspired many other frameworks. In the age of AI, Starlette continues to play an important role as a dependency of the Python MCP SDK.</p> <p>This release focuses on removing deprecated features that were marked for removal in 1.0.0, along with some last minute bug fixes. It's a release candidate, so we can gather feedback from the community before the final 1.0.0 release soon.</p> <p>A huge thank you to all the contributors who have helped make Starlette what it is today. In particular, I'd like to recognize:</p> <ul> <li><a href="https://github.com/lovelydinosaur">Kim Christie</a> - The original creator of Starlette, Uvicorn, and MkDocs, and the current maintainer of HTTPX.

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.
