5.10.0

(feat): Generate CONTRIBUTING.md for Python SDKs.

5.9.2

(fix): Widen the generated pydantic-core constraint from >=2.18.2,<2.44.0 to >=2.18.2,<3.0.0, unblocking customers who need newer pydantic-core (e.g. 2.46.x, required by pydantic 2.13). The previous cap targeted 2.44.0’s missing wheels; that release is yanked on PyPI, so the explicit cap is no longer needed.
