• 8.0.0-rc.1 - 2022-04-13
  

  This release candidate updates our peer deps to accept all React versions with hooks (16.8+, 17+, and 18+), as well as React Native (0.59+). (The code already worked, but the peer deps needed to be updated to match behavior and install correctly.)

  At this point, React-Redux v8 is feature-complete and stable. We still really want users to try this out and give us feedback before the final release! Barring any reported issues, we plan to release 8.0 as final within the next few days.

  What's Changed

  • Remove ts-ignore for initMergeProps by @ Methuselah96 in #1891
  • fix(deps): add optional peer deps into peerDependencies by @ kyletsang in #1893
  • Update peer deps for v8 by @ markerikson in #1895

  Full Changelog: v8.0.0-rc.0...v8.0.0-rc.1

• 8.0.0-rc.0 - 2022-04-10
  

  This release candidate removes the DefaultRootState type left over from the @ types/react-redux package. Additionally, we now have tests that exercise the serverState SSR behavior added in a previous beta.

  At this point, React-Redux v8 is feature-complete and stable. We still really want users to try this out and give us feedback before the final release! Barring any reported issues, we plan to release 8.0 as final within the next few days.

  Changelog

  Removal of the DefaultRootState type

  The @ types/react-redux package, which has always been maintained by the community, included a DefaultRootState interface that was intended for use with TS's "module augmentation" capability. Both connect and useSelector used this as a fallback if no state generic was provided. When we migrated React-Redux to TS, we copied over all of the types from that package as a starting point.

  However, the Redux team specifically considers use of a globally augmented state type to be an anti-pattern. Instead, we direct users to extract the RootState and AppDispatch types from the store setup, and create pre-typed versions of the React-Redux hooks for use in the app.

  Now that React-Redux itself is written in TS, we've opted to remove the DefaultRootState type entirely. State generics now default to unknown instead.

  Technically the module augmentation approach can still be done in userland, but we discourage this practice.

  SSR Tests

  We added a serverState prop to <Provider> in beta.2 to resolve hydration mismatch issues, but had only done some quick hands-on testing locally. We now have tests that cover that use case.

  What's Changed

  • Remove DefaultRootState type by @ markerikson in #1887
  • Add SSR test for serverState behavior by @ markerikson in #1888
  • Cleanup internal types in selectorFactory.ts by @ Methuselah96 in #1889

  Full Changelog: v8.0.0-beta.4...v8.0.0-rc.0

• 8.0.0-beta.4 - 2022-04-02
  

  This beta release switches the default entry point to use the useSyncExternalStore shim for compatibility with React 16.8+, and switches to a "/next" alternate entry point without the shim.

  At this point, React-Redux v8 is feature-complete and stable. We still really want users to try this out and give us feedback before the final release! We'd also like to add some additional tests around SSR behavior.

  We would like to release v8 as final within the next couple weeks now that React 18 is available.

  Changelog

  useSyncExternalStore Shim Usage

  React 18 adds the new useSyncExternalStore API. In previous betas, the plan was that React-Redux v8 would have a hard requirement on React 18. As a fallback, the betas provided a "/compat" entry point that included the uSES "shim", a userland implementation from the React team that provided compatibility with earlier React versions back to 16.8. That adds a few hundred bytes to the bundle size, so we wanted to keep the default size smaller.

  However, React Native will not support React 18 until the "New Architecture" is done. So, release React-Redux v8 with a hard React 18 requirement would immediately start breaking RN usage.

  After discussion with the React team, we've flipped the default behavior in v8. Now, the default entry point does rely on the uSES shim. This increases final bundle size slightly (about 600b minified compared to v7.x). However, this ensures that React-Redux v8 is compatible with React 16.8+/17 out of the box, enabling users to upgrade to v8 right away even if they aren't using React 18. It also ensures continued RN compatibility.

  For users who would like to strip out the shim, this release switches to having a "/next" entry point that directly imports useSyncExternalStore from React, with no shim. You can alias "react-redux": "react-redux/next" in your bundler to use that instead.

  What's Changed

  • Remove unused useCallback import by @ bobaekang in #1883
  • Swap useSyncExternalStore shim behavior and update React deps by @ markerikson in #1884

  Full Changelog: v8.0.0-beta.3...v8.0.0-beta.4

• 8.0.0-beta.3 - 2022-02-06
  

  This beta release fixes a regression with unsubscribe performance in useSelector, and does some minor internal cleanup in connect.

  At this point, React-Redux v8 is likely feature-complete and stable. We still really want users to try this out and give us feedback before the final release! We'd also like to add some additional tests around SSR behavior.

  The tentative plan is to do a final review of the code and behavior after React 18 goes final, then release React-Redux v8 final shortly after that.

  Changelog

  useSelector Unsubscribe Performance

  In 2019, we fixed a a reported issue with useSelector unsubscriptions showing quadratic performance, due to use of a single listeners array in our Subscription class. The fix was to switch to using a linked list to track subscribers.

  When we reworked useSelector to use useSyncExternalStore for v8, we passed store.subscribe directly and stopped subscribing via a Subscription instance, thinking that we might no longer need Subscription any more. However, Subscription is still used by <Provider>, so it won't be removed from the bundle anyway, and the switch to using store.subscribe regressed the unsubscription performance because it does still use a listeners array as well.

  We've switched back to having useSelector subscribe to the Subscription instance from <Provider>, and verified that this re-resolves the unsubscription performance behavior. We've also added a perf test to ensure that we capture this intended behavior and don't accidentally regress on this again in the future.

  Internal Cleanup

  We've removed a couple additional references to the removed pure option in connect, and tweaked some of the types to remove a legacy signature for Provider that is no longer relevant.

  What's Changed

  • test: Adjust type tests to be compatible with React 18 typings by @ eps1lon in #1868
  • Switch back to Subscription in useSelector to fix unsubscribe perf by @ markerikson in #1870
  • Cleanup more code after pure removal by @ Andarist in #1859

  Full Changelog: v8.0.0-beta.2...v8.0.0-beta.3

• 8.0.0-beta.2 - 2021-12-22
  

  This beta release makes several fixes to the TypeScript types for v8, fixes several dev dependencies that were accidentally listed as dependencies, and adds initial React 18 SSR support.

  Changelog

  TypeScript Fixes

  The initial TS conversion effort ported a chunk of the typetests from the React-Redux v7 types in DefinitelyTyped. We've ported over the remainder of the typetests, which uncovered a few bugs and missing types (such as the useStore hook not being generic).

  Those issues are now fixed, and after some additional tweaks all of the typetests are now passing. This means that existing TS usage of React-Redux v7 should be able to work entirely as-is with v8.

  React 18 SSR Support

  The new React 18 useSyncExternalStore hook accepts a function to supply the current state when called, which is normally the Redux store.getState method. However, a mutable store like Redux could change before or during an initial hydration render (such as a manual store.dispatch() before calling hydrateRoot(), or React components dispatching actions during the mount process). To avoid that, useSyncExternalStore also requires that you provide a getServerSnapshot function that can return a consistent single state value. uSES will use that all the way through the initial hydration render, and then check to see if any further updates are needed based on the latest state after the hydration render is complete.

  The Provider component now accepts an optional serverState prop. If you're doing SSR, serialize your Redux store state on the server and pass that in to Provider as <Provider store={store} serverState={window.initialServerState}>, similar to how you would initialize a Redux store with that value.

  We've updated both useSelector and connect to use the serverState value if it exists and pass that to useSyncExternalStore. This has been only briefly tested so far, but it appears to correctly eliminate hydration mismatch warnings.

  We would really like more users to try this out and give us feedback!

  Huge thanks to @ Ephem for providing an SSR example to work with, and @ acdlite for the API idea.

  Dependency Updates

  React-Redux now expects React 18 RC as a peer dep.

  Several test libraries were accidentally added as dependencies in the previous betas, so they would get installed in user projects as well. Those have been moved back to devDependencies as intended.

  What's Changed

  • fix: Add types to ensure that there will be no compilation errors when struct: false by @ duan602728596 in #1851
  • Port remaining v7 typetests and improve v8 types by @ markerikson in #1855
  • Add initial SSR support for React 18 and React-Redux v8 by @ markerikson in #1835

  Full Changelog: v8.0.0-beta.1...v8.0.0-beta.2

• 8.0.0-beta.1 - 2021-11-20
  

  This beta bugfix release fixes incorrect initialization of the useSyncExternalStore hook from beta.0 that caused it to crash on startup. Sorry!

  npm i react-redux@next

  yarn add react-redux@next


  What's Changed

  • Rework uSES init to not rely on module initialization order by @ markerikson in #1845

  v8.0.0-beta.0...v8.0.0-beta.1

• 8.0.0-beta.0 - 2021-11-19
  Read more
• 8.0.0-alpha.1 - 2021-11-02
• 8.0.0-alpha.0 - 2021-10-03
• 7.2.8 - 2022-04-01
  

  This release fixes a bug in the 7.x branch that caused <Provider> to unsubscribe and stop updating completely when used inside of React 18's <StrictMode>. The new "strict effects" behavior double-mounts components, and the subscription needed to be set up inside of a useLayoutEffect instead of a useMemo. This was previously fixed as part of v8 development, and we've backported it.

  Note: If you are now using React 18, we strongly recommend using the React-Redux v8 beta instead of v7.x!. v8 has been rewritten internally to work correctly with React 18's Concurrent Rendering capabilities. React-Redux v7 will run and generally work okay with existing code, but may have rendering issues if you start using Concurrent Rendering capabilities in your code.

  Now that React 18 is out, we plan to finalize React-Redux v8 and release it live within the next couple weeks. Per an update yesterday in the "v8 roadmap" thread, React-Redux v8 will be updated in the next couple days to ensure support for React 16.8+ as part of the next beta release. We would really appreciate final feedback on using React-Redux v8 beta with React 18 before we publish the final version.
