- [x] NatbotChain: move to community, deprecate langchain version. Update to use `prompt | llm | output_parser` instead of LLMChain. - [x] LLMMathChain: deprecate + add langgraph replacement example to API ref - [x] HypotheticalDocumentEmbedder (retriever): update to use `prompt | llm | output_parser` instead of LLMChain - [x] FlareChain: update to use `prompt | llm | output_parser` instead of LLMChain - [x] ConstitutionalChain: deprecate + add langgraph replacement example to API ref - [x] LLMChainExtractor (document compressor): update to use `prompt | llm | output_parser` instead of LLMChain - [x] LLMChainFilter (document compressor): update to use `prompt | llm | output_parser` instead of LLMChain - [x] RePhraseQueryRetriever (retriever): update to use `prompt | llm | output_parser` instead of LLMChain
