8.0.0

Commits: v7.1.0...v8.0.0

Breaking

• Relay Compiler no longer relies on the graphql-js schema representation. And consumes only SDL file that represents the schema. This means that all custom implementations relay compiler runners that were depended on the specifics of the graphql-js may not work as expected. Specifically, custom Enum values are no longer available in the relay-compiler - as they cannot be expressed via SDL. Also, custom function parseValue, parseLiteral and serialize that can be defined for a graphql type via graphql-js primitives are not accessible in the relay compiler: this may break serialization of custom scalars. 860c23c
• Babel plugin no longer produces thunks: 490c89d
• Mutations are committed to unique root ids #2349. In mutation updaters, fields in the mutation will no longer be available in the store root returned from store.getRoot. Usages like store.getRoot().getLinkedRecord('create_comment_mutation') will break.
• Removed internally unused RelayRecordSourceProxy::commitPayload(). Note that this method was not part of the public interface.
• Signature of RelayStore.retain() changed to directly accept an OperationDescriptor. An operation descriptor to pass to RelayStore.retain()can be constructed usingcreateOperationDescriptoravailable inrelay-runtime`.

Added

• Allow language plugin to add schema extensions. #2935
• In relay-compiler we added support for variables in complex objects and arrays: 5da3be0
• isClientID helper is available to use in relay-runtime dac614c

Fixed

• Remove the clientMutationId requirement by creating a new root id for each executed mutation: #2349

• validateMutation correctly handles lists of scalar fields in the optimistic payloads: 56795ba

• DissalowIDAsAlias this validation had a bug, there it wasn't traversing LinkedFields, hence wasn't reporting violations in their selections. c4547f9

• RelayModernFragmentSpecResolver only holds on to fragment references as opposed to all props passed to product code to reduce amount of leaked memory when rendering in React concurrent mode.

• Fixed detecting whether the execution environment is a server: #2960

Misc

• Relay codebase is using explicit inexact objects: 4e2cc2f
• Added an options property on IEnvironment for attaching extra information to the environment instance
• Updated docs to consider Relay server specifications GraphQL best practices and not purely a Relay spec: #2603
• https://relay.dev has a new landing page redesign: #2953

Experimental

• Data Invalidation: Added new Data Invalidation primitives to allow marking data in the Relay Store as stale. When data is marked as stale, queries that reference that data will also be stale; stale queries will indicate to Relay that they need to be refetched the next time they are evaluated.
• Deprecate LazyLoadEntryPointContainer => LazyLoadEntryPointContainer_DEPRECATED: 08bde91
• Removed Unused types from RelayStoreTypes 76354e9
• usePreloadedQuery now takes an unstable UNSTABLE_renderPolicy like useLazyLoadQuery: fc1b88b
• useMutation Hook was added: 96d9703
• Export a JSResource Flow interface from Relay.
• Fixed subscribing to plural fragments with missing data when using useFragment.
