Commits: v4.0.0...v5.0.0

Breaking

• react-relay containers no longer consume variables from React context, but instead from fragment owners passed through fragment refs. This means that if you have a custom QueryRenderer or other component that set Relay Context, setting variables on that context will no longer affect descendant components.

Added

• Expose ability to pass custom scalar configuration to compiler (#2745 by @alloy)
• Add relay-config package to manage compiler configs (#2746 by @alloy)

Improved

• Improved DX for working on Relay as non-FB dev (#2749 by @alloy)
• Added Support for getDataID() function: 311412b
• Updated Internal Testing Tools to explicitly mark fixtures that should throw: https://github.com/facebook/relay/commit/a6b388b598c18f83811699ef1eea00887b5d217
• Added Memoization for Compiler Transforms:
  • InlineFragmentTransfrom
  • FlattenTransform and ClientExtensionsTransform
  • SkipRedundantNodes
  • RelayGenerateTypeName
• Relay Testing Tools Update: Handle Arrays in MockResolvers
• Refetchable fragments are allowed on abstract types not directly implementing Node: 87930e1
• ID field is now automatically added to @refetchable fragments on types implementing Node: 3efecaa

Fixed

• Updated default compiler configuration to include files from __tests__ directories: 033a4bb
• Fixed a bug in flow type generation that fields on inline fragments with duplicated names are only included once: [088afdf](https://github.com/facebook/relay/commit/088afdf347582533b9956adbc5b2a5e37fe9cfaf)
• Deduplicate connection edges based on DataID (not just id field)
• Fixed a bug that mutations on viewer field “overwriting” existing fields in the store: Add hardcoded ID to viewer field

• Upgrade Docusaurus to 1.9.0
