Example Code

from langchain.chains.summarize import load_summarize_chain
from langchain_core.prompts import PromptTemplate

def map_reduce(input_document):
    summary_chain = load_summarize_chain(
        llm = self.client,
        chain_type = "map_reduce",
        map_prompt = PromptTemplate(template=self.map_prompt, input_variables=["text"],
        combine_prompt = PromptTemplate(template=self.stuff_prompt, input_variables=["text"]
    )
    return summary_chain.invoke(input_document)

Description

I'm trying to use langchain library load_summarize_chain to load the map-reduce chain. This works as expected currently but I see that it uses MapReduceDocumentsChain,(from _load_documents in load_summarize_chain) which is deprecated and will be removed for v1.0. Is this something that will be addressed in v1.0 and adjusted to use LangGraph instead? Or is this something I need to address in my repository to keep it working once we upgrade to v1.0? This is also a similar situation to StuffChainDocumentsChain and the rest of the v0.0 chains.
