Not sure what the situation is like now, but we stopped using LangChain last year because the rate of change in the library was huge. Whenever we needed to upgrade for a new feature or bug fix we’d be 20~ versions behind and need to work through breaking changes. Eventually we decided that it was easier to just write everything ourselves.

This is from the first half of 2023 or so; maybe things are more stable now, but looks like the Python implementation is still pre-v1.
