Support langchain 0.2.* #792
Description
Description
Langchain 0.2.* has been released, but you require langchain-core = "^0.1.18" which is equal to langchain-core<0.2.0,>=0.1.18.
You should support the newest versions of langchain.
Why is this needed
The newer version of langchain has bugfixes and new features. You should allow your users to use the newest version of langchain, so they can benefit from these bugfixes and features.
Implementation details
Update your langchain requirements in pyproject.toml, then fix any bugs caused by breaking changes. (Probably easy, but who knows...)
End result
Users can install guardrails alongside langchain==0.2.0.
