Last updated: February 25, 2026

What's New In This Refresh

• Updated embeddings guidance for Chroma 1.5.3.
• Replaced legacy vector store imports with from langchain_chroma import Chroma.
• Replaced deprecated adapter usage with ChromaLangchainEmbeddingFunction.
• Added a full runnable example: examples/langchain/python/embeddings_example.py
• Added example dependencies: examples/langchain/requirements.txt
• Documented a Chroma 1.5.3 query workaround for wrapped LangChain embeddings.

Guides

• Embeddings - use LangChain embedding models with Chroma collections and langchain_chroma.
• Retrievers - use LangChain retrievers with Chroma.
