Original Pull Request: https://github.com/langchain-ai/langgraph/pull/3843

State: closed
Merged: Yes

LangGraph officially supported Python 3.13 back in October 2024:
https://changelog.langchain.com/announcements/langgraph-is-now-compatible-with-python-3-13

But why suggest restricting the version of Python at all? The app/agent owner will be in control of the runtime version anyway, so don't add unnecessary restrictions.

Note this example from Poetry: https://python-poetry.org/docs/pyproject/#requires-python

I did not refactor pyproject.toml to the newer Poetry 2 / uv format, but I can do that in a future PR if it will help... please don't let that block approval+merging this PR.
