Major Changes

• #12478 5ea6a45 Thanks @jerelmiller! - Remove variables from the result returned from useSubscription.

• #12476 6afff60 Thanks @jerelmiller! - Subscriptions now emit a SubscribeResult instead of a FetchResult. As a result, the errors field has been removed in favor of error.

• #12475 3de63eb Thanks @jerelmiller! - Unify error behavior on mutations for GraphQL errors and network errors by ensuring network errors are subject to the errorPolicy. Network errors created when using an errorPolicy of all will now resolve the promise and be returned on the error property of the result, or stripped away when the errorPolicy is none.

• #12475 3de63eb Thanks @jerelmiller! - client.mutate now returns a MutateResult instead of FetchResult. As a result, the errors property has been removed in favor of error which is set if either a network error occured or GraphQL errors are returned from the server.

  useMutation now also returns a MutateResult instead of a FetchResult.

• #12475 3de63eb Thanks @jerelmiller! - Mutations no longer report errors if the GraphQL result from the server contains an empty array of errors.

• #12476 6afff60 Thanks @jerelmiller! - Unify error behavior on subscriptions for GraphQL errors and network errors by ensuring network errors are subject to the errorPolicy. Network errors that terminate the connection will now be emitted on the error property passed to the next callback followed by a call to the complete callback.

• #12478 5ea6a45 Thanks @jerelmiller! - Remove deprecated onSubscriptionData and onSubscriptionComplete callbacks from useSubscription. Use onData and onComplete instead.

• #12476 6afff60 Thanks @jerelmiller! - GraphQL errors or network errors emitted while using an errorPolicy of ignore in subscriptions will no longer emit a result if there is no data emitted along with the error.

• #12476 6afff60 Thanks @jerelmiller! - Subscriptions no longer emit errors in the error callback and instead provide errors on the error property on the result passed to the next callback. As a result, errors will no longer automatically terminate the connection allowing additional results to be emitted when the connection stays open.

  When an error terminates the downstream connection, a next event will be emitted with an error property followed by a complete event instead.

Minor Changes

• #12487 b695e5e Thanks @phryneas! - Split out SSR-specific code from useQuery hook, remove RenderPromises

Patch Changes

• #12487 b695e5e Thanks @phryneas! - useQuery with ssr: false - previously, skip had a higher priortity than ssr: false while ssr: false had a higher priority than fetchPolicy: "standby" (which is roughly equivalent to skip).

  This priority has been adjusted so now both skip and fetchPolicy: "standby" have a higher priority than ssr: false and will return loading: false, while ssr: false will only come after those and will return loading: true if those are not set.

• #12475 3de63eb Thanks @jerelmiller! - Fix an issue where passing onError to useMutation would resolve the promise returned by the mutate function instead of rejecting when using an errorPolicy of none.

• #12475 3de63eb Thanks @jerelmiller! - Fix an issue where additional response properties were returned on the result returned from client.mutate, such as @defer payload fields. These properties are now stripped out to correspond to the TypeScript type.
