Commits: v1.7.0-rc.1...v2.0.0-rc.1
Breaking
- Relay now uses new Context API instead of Legacy Context API. Any consumers of Relay context using the Legacy context API will break.
- Although not officially supported, this change also breaks SSR with Relay: #2544. We will fix this issue in 2.0.0-rc.2.
- Removed experimental support for @deferrable directive
- Upgrade graphql to 14.0.0
- Upgrade react to 16.5.0
- relay-compiler: Rename inputFieldWhitelist to optionalInputFields.
Added
- Add 'severity' field to PayloadError in RelayNetwork interface.
- Add support for specifying missingFieldHandlers in the Relay environment. These handlers allow developers to provide a fallback for missing data for a query when environment.check() is called.
- Add support making GC scheduling configurable in the Relay environment.
- Allow passing a custom handler to @connection. This is useful for products that want to customize the way newly fetched items are merged into an existing connection.
Experimental
Added a new relay-experimental package which exposes a few experimental APIs.
- Add fetchQuery_UNSTABLE api to fetch and retain data outside of React.
- Add SuspenseQueryRenderer and SuspenseFragmentContainer. These are new versions of our containers that use Suspense to communicate loading states.
Fixed
- Fix incorrectly garbage collecting data during an optimistic update.
- Correctly fix double fetching with QueryRenderer in React Concurrent mode.
- Fix rendering sibling QueryRenderers that have the same query and variables.
Improved
- Upgrade build dependencies to Babel 7 and Webpack 4.
- Make generated Flow types for Input types exact objects.
- Simplify structure of network payloads.
- Rename RelayMarkSweepStore to RelayModernStore.
