Release Notes

v4.2.9

Compare Source

Patch Changes

• #​13364 2f383e7 Thanks @​atharv-sys32! - Fix a bug where GraphQL variable default values were not applied during cache reads when variables with defaults were explicitly set to undefined. This caused @include/@skip directives to throw "Invalid variable referenced" errors when the variable was passed as undefined instead of being omitted entirely.

• #​13367 2b39cc8 Thanks @​jerelmiller! - Fix an issue where some @export queries would not react to cache updates when the fields keyed by exported variables were updated.

v4.2.8

Compare Source

Patch Changes

• #​13349 501a33b Thanks @​jerelmiller! - Prevent the setTimeout in connectToDevtools that shows the devtools suggestion from firing when the user agent does not match Chrome or Firefox. This check was previously done inside the setTimeout which meant the timer was scheduled for environments where we'd never show the message anyways. For test environments, this could cause flaky tests when that setTimeout outlived the tests and ran after any virtual DOM was torn down and removed.

v4.2.7

Compare Source

Patch Changes

• #​13320 538c906 Thanks @​jerelmiller! - Cleanup some unused internals. Please file an issue if you notice anything change.

v4.2.6

Compare Source

Patch Changes

• #​13315 a406cc9 Thanks @​fallintoplace! - Prevent relay multipart subscriptions from issuing a fetch request after serializing the request body fails.

• #​13307 abd0781 Thanks @​wolfie! - Speed up cache writes by avoiding a full AST visit of every written field to detect @stream. The check now runs only when the result carries stream info, and only inspects the field node's own directives. As a result, fields that merely contain @stream on a nested field are no longer treated as streamed themselves and now overwrite existing lists like regular fields instead of merging chunk-wise.

v4.2.5

Compare Source

Patch Changes

• #​13302 bb75dd3 Thanks @​tpict! - Export KeyArgsFunction and RelayFieldPolicy types from public entrypoints.

v4.2.4

Compare Source

Patch Changes

• #​13281 e4df809 Thanks @​jerelmiller! - Fixes an issue where client.readFragment and client.readQuery ignored the optimistic option when passed in the options object.
