Improve the Suspense implementation, which fixes edge-cases when Suspense is used with subscriptions, partially disabled, or used on the client-side. It has now been ensured that client-side suspense functions without the deprecated suspenseExchange and uncached results are loaded consistently. As part of this work, the Client itself does now never throw Suspense promises anymore, which is functionality that either way has no place outside of the React/Preact bindings, by @kitten (See #1123)

Use Record over object type for subscription operation variables. The object type is currently hard to use (see this issue), by @enisdenjo (See #1119)
Add support for TypedDocumentNode to infer the type of the OperationResult and Operation for all methods, functions, and hooks that either directly or indirectly accept a DocumentNode. See graphql-typed-document-node and the corresponding blog post for more information., by @kitten (See #1113)
Refactor useSource hooks which powers useQuery and useSubscription to improve various edge case behaviour. This will not change the behaviour of these hooks dramatically but avoid unnecessary state updates when any updates are obviously equivalent and the hook will furthermore improve continuation from mount to effects, which will fix cases where the state between the mounting and effect phase may slightly change, by @kitten (See #1104)
