When will AWS Bedrock support anthropic.claude-3-5-sonnet-20241022-v2:0?

Is there an openai 1.x migration guide, I am currently in a trial-and-error mode, stepping onto landmines one after another, even after reading the openai 1.0 migration guide.

I am hitting an ImportError: cannot import name 'LLM' from 'llama_index.core.llms':

Traceback (most recent call last):
File "/Users/mingqxu/Projects/chat-sop/llindex_ingest.py", line 27, in <module>
from llama_index.vector_stores.faiss import FaissVectorStore

Is ColbertIndex gone? I haven't updated llama-index since v0.9.45post1 until today. I can't find ColbertIndex anymore.
