Major Changes

• #12222 d1a9054 Thanks @jerelmiller! - Drop support for React 16.

• #12224 51e6c0f Thanks @jerelmiller! - Remove deprecated partialRefetch option.

• #12211 c2736db Thanks @jerelmiller! - Remove the deprecated graphql, withQuery, withMutation, withSubscription, and withApollo hoc components. Use the provided React hooks instead.

• #12262 10ef733 Thanks @jerelmiller! - Remove itAsync test utility.

• #12304 86469a2 Thanks @jerelmiller! - The Cache.DiffResult<T> type is now a union type with better type safety for both complete and partial results. Checking diff.complete will now narrow the type of result depending on whether the value is true or false.

  When true, diff.result will be a non-null value equal to the T generic type. When false, diff.result now reports result as DeepPartial<T> | null indicating that fields in the result may be missing (DeepPartial<T>) or empty entirely (null).

• #12254 0028ac0 Thanks @jerelmiller! - Changes the default Accept header to application/graphql-response+json.

• #12223 69c1cb6 Thanks @jerelmiller! - Remove subscribeAndCount testing utility from @apollo/client/testing.

• #12300 4d581e4 Thanks @jerelmiller! - Moves all React-related exports to the @apollo/client/react entrypoint and out of the main @apollo/client entrypoint. This prevents the need to install React in order to use the core client.

  The following is a list of exports available in @apollo/client that should now import from @apollo/client/react.

  • ApolloConsumer
  • ApolloProvider
  • createQueryPreloader
  • getApolloContext
  • skipToken
  • useApolloClient
  • useBackgroundQuery
  • useFragment
  • useLazyQuery
  • useLoadableQuery
  • useMutation
  • useQuery
  • useQueryRefHandlers
  • useReactiveVar
  • useReadQuery
  • useSubscription
  • useSuspenseQuery

  The following is a list of exports available in @apollo/client/testing that should now import from @apollo/client/testing/react:

  • MockedProvider

• #12304 86469a2 Thanks @jerelmiller! - ### Changes for users of InMemoryCache

  cache.diff now returns null instead of an empty object ({}) when returnPartialData is true and the result is empty.

  If you use cache.diff directly with returnPartialData: true, you will need to check for null before accessing any other fields on the result property. A non-null value indicates that at least one field was present in the cache for the given query document.

  Changes for third-party cache implementations

  The client now expects cache.diff to return null instead of an empty object when there is no data that can be fulfilled from the cache and returnPartialData is true. If your cache implementation returns an empty object, please update this to return null.

• #12304 86469a2 Thanks @jerelmiller! - ### Changes for users of InMemoryCache

  cache.diff no longer throws when returnPartialData is set to false without a complete result. Instead, cache.diff will return null when it is unable to read a full cache result.

  If you use cache.diff directly with returnPartialData: false, remove the try/catch block and replace with a check for null.

  Changes for third-party cache implementations

  The client now expects cache.diff to return null instead of throwing when the cache returns an incomplete result and returnPartialData is false. The internal try/catch blocks have been removed around cache.diff. If your cache implementation throws for incomplete results, please update this to return null.

• #12211 c2736db Thanks @jerelmiller! - Remove the deprecated Query, Mutation, and Subscription components. Use the provided React hooks instead.

Patch Changes

• #12291 ae5d06a Thanks @phryneas! - Remove deprecated resetApolloContext export

• #12321 daa4f33 Thanks @jerelmiller! - Fix type of extensions in protocolErrors for ApolloError and the onError link. According to the multipart HTTP subscription protocol, fatal tranport errors follow the GraphQL error format which require extensions to be a map as its value instead of an array.
