# Zep Retriever - Vector Search Over Chat History with the Zep Long-term Memory Service More on Zep: https://github.com/getzep/zep Note: This PR is related to and relies on #4834. I did not want to modify the `pyproject.toml` file to add the `zep-python` dependency a second time. Co-authored-by: Daniel Chalef <daniel.chalef@private.org>

Langchain Message History support for the Zep long-term memory service: Memory persistence, summarization, vector search, and message enrichment.
More on Zep: https://github.com/getzep/zep
The ZepChatMessageHistory class supports chat message persistence and recall, message history summarization, and vector search. For search, we'll create a separate PR for a Retriever.
The class also exposes Zep's enriched message history, including message token counts, timestamps, and more. In future, this will include session and message-specific metadata.
Required dependency:
Before submitting
Notebook included. Integration testing requires standing up Zep and Postgres service containers in your project's GitHub CI. Let me know if this is feasible, and we'll share a recipe.
