Hi, thanks for your contribution! We fixed the langchain version because there might be unexpected changes in new versions. Changing to the latest version means we have to test all functions. Do you have suggestions on that? We'll appreciate that!

Agreed that the new langchain and pydantic version will break the Openagent code, I have made all the possible changes into openagent code in my local branch and tested the changes which seems working fine, happy to create a pull request for all the changes required.
We have to upgrade these new libs as lots of new features and modules being added recently in the lllm open source world , this will make openagent more attractive and easy to integration with other apps.
