Namespaces and Pinecone v4

langchain depreciated namespace as a parameter. they claim it was in preparation for pinecone v4. I can’t find anything about namespaces being depreciated and no information on pinecone v4 either. Was this removal in langchain unwarranted or was a breaking change and an api update not communicated?

Apparently the namespace feature will be scraped from the new free starter plan. But i don’t know if it will be gone entirely. i hope not because i rely on this feature. i am using flowise, which uses langchain, and atm it still has namespaces as a parameter. i’m also wondering of the namespace feature will be scraped from existing free plan users.

We’ve reverted the change to langchain. Existing indexes are not impacted and namespaces will continue to remain part of our paid product.
