Native retry promises and hydration resolution
packages/query-core/src/retryer.ts, packages/query-core/src/hydration.ts
Replaces retryer thenables with native promises and local status tracking.
Framework hook and suspense integration
packages/react-query/..., packages/preact-query/..., packages/solid-query/src/useBaseQuery.ts
Removes render-time prefetch handling, willFetch, and experimental-option checks.
Adapter results and cross-framework validation
packages/lit-query/..., packages/react-query/src/__tests__/*, packages/preact-query/src/__tests__/*, packages/solid-query/src/__tests__/*, packages/svelte-query/tests/*, packages/query-core/src/__tests__/queryObserver.test.tsx
Removes promise fields, promise assertions, feature-flag setup, and promise-specific tests.
Documentation and release metadata
docs/framework/react/..., .changeset/quiet-flags-remove.md
Removes React useQuery().promise, React.use(), and render-prefetch documentation. Adds patch release metadata.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to ba0ca

The retry logic may fail strict TypeScript compilation because callback variables could be used before assignment. This should be fixed or explicitly accepted before merging.

@TkDodo it's been a long time since I last heard about this on bluesky. Has there been any updates on how, in the future, react will help supporting this?

I'm not sure if there have been any progress on making a transition compatible uSES hook.

this is a slightly different topic, but to fully support react transitions, we would need a concurrent compatible useStore hook from react. It doesn’t seem like we’re getting that though
