  1. This **feature release** updates our build tooling to TSDown and PNPM, adds official TypeScript 7 support, and includes a long list of bugfixes across RTK Query, `createAsyncThunk`, `createEntityAdapter`, and `combineSlices`.
  3. ## Changelog
  5. ### Build Tooling Updates
  7. We've fully modernizing modernized our build tooling across all of the Redux repos. That included switching from Yarn to PNPM, ESLint to Oxlint, Prettier to Oxfmt, and TSUp to TSDown.
  9. The part that matters for users is that we now build the package with [TSDown](https://tsdown.dev) instead of `tsup`. The package layout, `exports` definitions, and exported APIs are all unchanged from 2.12. We've checked the new build with `attw`, and verified that CJS and ESM entry points load in both dev and prod builds, and that the `legacy-esm` artifacts still target ES2017. The contents of the bundles do look a bit different (smaller CJS artifacts, slightly different helper output in the `legacy-esm` files). If you see any behavior differences that look build-related, please file an issue!
  11. This is also our first release published via the updated PNPM-based workflow, still using NPM Trusted Publishing. We've also added `pkg.pr.new` previews for every commit, so you can try out a PR build before it's released.
  13. ### Docs Updates
  15. We've shipped a new combined Redux libraries docs site! The core docs site at https://redux.js.org now contains the docs for _all_ of our libraries: Redux core and usage guides, Redux Toolkit, React Redux, and Reselect. The prior standalone docs sites for RTK, R-R, and Reselect now redirect to their respective sections of the combined docs. We've also done a major cleanup pass on the docs, deduplicating pages that had similarities (like the Next.js or RTK2 migration pages that lived in both the core and RTK docs), and updating outdated content (modernizing example code snippets, deleting dead links, and making RTK and hooks the default patterns shown). The RTK content now lives at https://redux.js.org/toolkit/ .
  17. ### TypeScript 7 Support
  19. TS 7.0 (the native Go port) is now out! We fixed the remaining type errors in RTK when checked by TS 7.0 and 7.1, and TS 7.0 is now part of our CI test matrix.
  21. Per our TS support policy of matching DefinitelyTyped's support window, we've also updated our support matrix to TS 5.6+. As always, RTK may still work with earlier versions, but we no longer test against them.
  23. ### RTK Query Fixes
  25. `useQueryState` (and thus `useQuery`) was passing a new inline selector to `useSelector` on every render, and also reading the store directly during render. The selector is now memoized, and the direct store read is gone. This also fixes a bug where `isSuccess` could flip from `false` to `true` on an unrelated re-render while a query was refetching after an error. `isSuccess` now correctly stays `false` in that case.
  27. `data` now reflects cache updates made via `updateQueryData` while a refetch is in flight, instead of showing the previous result.
  29. Polling now reads the current cache state when each poll fires, rather than the state at the time the poll was scheduled. This means `skipPollingIfUnfocused` respects focus loss that happens after scheduling, and polls stop if their cache entry was removed.
  31. We fixed a race where a duplicate query request rejected by the thunk condition could cause queued tag invalidations to run too early and be lost, leaving stale data in the cache.
  33. Tags with falsy ids like `0` now invalidate and clean up correctly.
  35. Lazy query hooks now re-subscribe correctly when effects restart while the hook state is preserved, such as with Fast Refresh or `<Activity>`.
  37. Infinite queries no longer trigger `onQueryStarted` when fetching past the end of the list, and the infinite query hook result type now includes the page error flags.
  39. `fetchBaseQuery` only treats a URL as absolute if it starts with a scheme.
  41. We also fixed an error when rehydrating state for an endpoint name that has no definition.
  43. ### Other Fixes
  45. `createAsyncThunk` no longer swallows aborts that happen before the `pending` action is dispatched, and now correctly sets `rejectedWithValue` when `rejectWithValue` is called with a falsy payload.
  47. `createEntityAdapter`'s `setAll` now keeps the last item when given duplicate IDs, matching `setMany`. The sorted adapter's `updateMany` now merges multiple updates for the same ID before applying them.
  49. `combineSlices` now keeps its internal state proxy cache per instance, so multiple combined reducers no longer interfere with each other.
  51. The immutability check middleware now handles circular references in state.
  53. The dynamic middleware now caches its composed middleware chains when the list of middleware hasn't changed.
