Breaking Changes - Upgrade
This release adds support for Trio. ✨
It upgrades the version of Starlette to 0.15.0, now based on AnyIO, and the internal async components in FastAPI are now based on AnyIO as well, making it compatible with both asyncio and Trio.
You can read the docs about running FastAPI with Trio using Hypercorn.
This release also removes graphene as an optional dependency for GraphQL. If you need to work with GraphQL, the recommended library now is Strawberry. You can read the new FastAPI with GraphQL docs.
