Issue: Compatibility issues with LangChain between different versions

[YingChen1996]

Issue you'd like to raise.

Hi, we frequently encounter breaking issues during development recently due to LangChain daily release. May I ask how do you plan to solve this problem in the future and recommend users to use LangChain with compatibility issues? Thanks!

For example, we import CallbackManager like this in langchaine version <=0.0.153 from langchain.callbacks.base import CallbackManager but in the latest version, the class has been moved to manager.py and break our test, we need update code to from langchain.callbacks.manager import CallbackManager to fix it
