I think we should call out that we depend on langchain_classic now, since it is a heavy dependency that might not be obvious why it ended up in a user's environment.

These same dependencies (or close to) already exist in langchain < 1.0. What I would mention is that. "Note: langchain_mongodb 0.8.0 depends on langchain_classic, so still has the heavy dependency set than langchain did before the v1 refactor."

[NoahStapp]

Is the updated wording sufficient?

Did you call out langchain-classic?

[NoahStapp]

The latest commit does.

LGTM!

Looking into the test failure for test_toolkit_response with error ValueError: Failed to parse aggregation pipeline: name '_id' is not defined.
