-------------------

This release allows background tasks to be set with the ASGI integration. Tasks can be set on the response in the context, and will then get run after the query result is returned.

python
from starlette.background import BackgroundTask


strawberry.mutation
def create_flavour(self, info: strawberry.Info) -> str:
info.context["response"].background = BackgroundTask(...)

-------------------

This release caches attributes on the `Info` type which aren't delegated to the core info object.

-------------------

This releases fixes an issue where you were not allowed
to use duck typing and return a different type that the
type declared on the field when the type was implementing
an interface. Now this works as long as you return a type
that has the same shape as the field type.

-------------------

This release improves execution performance significantly by lazy loading
attributes on the `Info` type 🏎

-------------------

This release adds support for asynchronous hooks to the Strawberry extension-system.
All available hooks can now be implemented either synchronously or asynchronously.

It's also possible to mix both synchronous and asynchronous hooks within one extension.


python
from strawberry.extensions import Extension


class MyExtension(Extension):
async def on_request_start(self):
print("GraphQL request start")

def on_request_end(self):
print("GraphQL request end")
