## Problem The Poetry caret constraint `^0.115.0` in `sdk-python/pyproject.toml` resolves to `>=0.115.0,<0.116.0` for 0.x versions (per [PEP 440 / Poetry docs](https://python-poetry.org/docs/dependency-specification/#caret-requirements)). This blocks installation alongside any FastAPI release since **0.116.0 (June 2025)**. Current stable FastAPI is **0.129.0** — 14 minor versions ahead of the ceiling. ## Impact - Cannot `pip install copilotkit` in any project using FastAPI >=0.116.0 - Multiple users blocked (see #2771 comments) - Our production project has **~90 tests bypassed** with `COPILOTKIT_AVAILABLE = False` guards because of this ## Fix ```diff - fastapi = "^0.115.0" + fastapi = ">=0.115.0,<1.0.0" ``` This allows all current and future 0.x FastAPI releases while still capping at the upcoming 1.0 major version boundary, which may introduce breaking changes. ## Testing - The SDK uses standard FastAPI features (routing, dependency injection, middleware) that have been stable across all 0.11x–0.12x releases - No FastAPI APIs used by the SDK were deprecated or removed in 0.116.0–0.129.0 - `ag-ui-langgraph` (also in deps) uses `>=0.115.0` without an upper bound, so this change aligns the two constraints ## Note on `ag-ui-langgraph` `ag-ui-langgraph[fastapi]` also depends on FastAPI. Its constraint is already `>=0.115.0` (no ceiling), so this change to `copilotkit` is the only fix needed. Fixes #2771
