# Releases
## @apollo/client@4.2.9

### Patch Changes

- [#13364](#13364)
[`2f383e7`](2f383e7)
Thanks [@atharv-sys32](https://github.com/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](#13367)
[`2b39cc8`](2b39cc8)
Thanks [@jerelmiller](https://github.com/jerelmiller)! - Fix an issue
where some `@export` queries would not react to cache updates when the
fields keyed by exported variables were updated.
