subscribe breaking change in graphql version 3.3.0a3

[leszekhanusz]

It seems we don't need to use await anymore with the subscribe method since the latest 3.3.0a3 pre-release.

This causes current gql tests to fail with either:

• TypeError: object async_generator can't be used in 'await' expression
• TypeError: object ExecutionResult can't be used in 'await' expression

That new interface seems cleaner but could you please maybe indicate that breaking change in the release notes?

Thanks,

Right, this is a breanking change that is now mentioned in the release notes. It mirrors a similar change in GraphQL.js.
