Breaking

  • Arguments passed to the filters keyword for the @connection directive will now throw if they are invalid instead of being a no-op. [2dd7954]

Flow-related breaking changes:

  • Explicit type annotations are no longer needed for commitMutation [603ce54] and useMutation [051e469].
  • Records can no longer be modified directly and can only be passed to utility functions such as those in RelayModernRecord.js. [21a896c]
  • Added the babel-plugin-syntax-hermes-parser plugin, which switches Babel to use hermes-parser instead of @babel/parser, and enables full syntax support for Flow. [c320a89]
  • [1d95ce2] - Make React.Element fully opaque

TypeScript-related breaking changes:

  • Empty variables will now be typed as Record<PropertyKey, never> instead of as {} to represent an object without properties. [16910c9] (#4404)
  • Nullable fields will now yield a union of the actual type, null and undefined (T | null | undefined) instead of (T | null). To keep the old type generation behavior for now, you may set the typescriptExcludeUndefinedFromNullableUnion feature flag in the relay-compiler config as follows. Note the feature flag will be removed in a future release. [cc47bc9] (#4380) 
{
  "language": "typescript",
  "typescriptExcludeUndefinedFromNullableUnion": true
}

Experimental

Relay Resolvers are an experimental feature of Relay which allows you to model derived data, and soon client state, in your Relay graph. Since our last release we’ve put considerable work into stabilizing the feature. This includes bug fixes across our compiler, type generation, runtime and LSP (editor integration). In particular, contributors have fixed a number of bugs which made it impossible to use Relay Resolvers with TypeScript.

Documentation:

  • [bd95f00] - Updates RelayResolvers docs to include terse syntax and updates to the module resolution details
