Summary
This patch release adds a type‑safe `skipToken` for query skipping, fixes unhandled promise rejections and invariant handling, and switches to a named `equal` export from `@wry/equality`, which requires import updates.
⚠️ Breaking Changes
- The default export from "@wry/equality" was removed. Code that imported the equality function as a default import must be updated to use the named export `equal`.
Migration Steps
- Replace any default import of the equality helper from "@wry/equality" with a named import: `import { equal } from "@wry/equality";`.
- When skipping a query, replace `skip: true` with the `skipToken` value imported from "@apollo/client/react".
- Ensure that code handling the promise returned by `mutate` includes proper rejection handling or relies on the library's built‑in handling.
✨ New Features
- Added support for `skipToken` with `useQuery` to provide a type‑safe way to skip query execution instead of using `skip: true`.
🐛 Bug Fixes
- Prevent unhandled promise rejections from the promise returned by the `mutate` function of the `useMutation` hook.
- Fixed an issue where calling `invariant` from external libraries would throw when no dev error message handler was loaded.
