Full Changelog: reduxjs/react-redux@v7.2.8...v7.2.9
v7.2.8Compare Source
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 auseLayoutEffectinstead of auseMemo. 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.

v7.2.7Compare Source
This release updates React-Redux v7's peer dependencies to accept React 18 as a valid version, only to avoid installation errors caused by NPM's "install all the peer deps and error if they don't match" behavior.

Just a quick fix for a Yarn install warning. Sorry about the noise!
Changes
workspacesfrom our package.json to silence a Yarn warning (@timdorr)v7.2.5Compare Source
This release shrinks the size of our internal
Subscriptionclass, and updatesuseSelectorto avoid an unnecessary selector call on mount.Changes
Subscription Size Refactor
Our internal
Subscriptionimplementation has been written as a class ever since it was added in v5. By rewriting it as a closure factory, we were able to shave a few bytes off the final bundle size.useSelectorMount OptimizationA user noticed that
useSelectorhad never been given an early "bail out if the root state is the same" check to match howconnectworks. This resulted in a usually-unnecessary second call to the provided selector on mount. We've added that check.Entry Point Consolidation
We've consolidated the list of exported public APIs into a single file, and both the
index.jsandalternate-renderers.jsentry points now re-export everything from that file. No meaningful change here, just shuffling lines of code around for consistency.Other Updates
React-Redux v8 and React 18 Development
With the announcement of React 18, we've been working with the React team to plan our migration path to keep React-Redux fully compatible with React's upcoming features.
We've already migrated the React-Redux main development branch to TypeScript, and are prototyping compatibility implementation updates. We'd appreciate any assistance from the community in testing out these changes so that we can ensure React-Redux works great for everyone when React 18 is ready!
Internal Tooling Updates
Our
masterbranch now uses Yarn v2 for package management, is built with TypeScript, and we've made CI updates to test against multiple TS versions.The
7.xbranch has also been updated to use Yarn v2 for consistency.These only affect contributors to the React-Redux package itself.
Changelog
v7.2.4Compare Source
This release drops our dependency on the core
reduxpackage by inliningbindActionCreators, and tweaksuseSelectorto ensure that selectors aren't run an extra time while re-rendering.Changelog
Redux Dependency Removal
React-Redux has always imported the
bindActionCreatorsutility from the corereduxpackage for use inconnect. However, that meant that we had to have a peer dependency onredux, and this was the only reason we actually required thatreduxbe installed. This became more annoying with the arrival of Redux Toolkit, which has its own dependency onreduxinternally, and thus users typically saw peer dependency warnings saying that "reduxisn't listed as a dependency in your app".Code reuse across separate packages is a great thing, but sometimes the right thing to do is duplicate code. So, we've inlined
bindActionCreatorsdirectly into React-Redux, and we've completely dropped the dependency on Redux. This means that React-Redux will no longer produce a peerDep warning when used with Redux Toolkit, and<Provider>andconnectreally only need a Redux-store-compatible value to work right.useSelectorFixesUsers reported that
useSelectorwas re-running selector functions again unnecessarily while rendering after a dispatch. We've tweaked the logic to ensure that doesn't happen.useSelectoralso now has checks in development to ensure thatselectorandequalityFnare functions.Changes
v7.2.3Compare Source
This release improves behavior in
useSelectorby returning the existing reference if the newly returned selector result passes the equality check, and adds a hard dependency on the@types/react-reduxpackage to ensure TS users always have the typedefs installed.Changes
useSelectorResults ReuseIssue #1654 reported that
useSelectorwas returning new references from a selector even if the equality comparison function returnedtrue. This is because the equality check was only ever being performed during the action dispatch process.We now run the equality comparison against the value calculated by the selector while rendering, and return the existing reference for consistency if the old and new values are considered equal. This should improve some cases where further derived values where being recalculated unnecessarily.
TS Types Now Included
React-Redux has always been written in plain JS, and the typedefs maintained by the community in DefinitelyTyped. We plan on eventually rewriting the library in TypeScript in a future React-Redux v8 release, but until then the types can stay in DT.
However, having to always manually install
@types/react-reduxis annoying, and some users have gotten confused by that. This release adds a hard dependency on@types/react-redux, so that if you installreact-redux, you automatically get the types as well. This should simplify the process for TS users.Docs Updates
We've made several docs updates recently:
We are currently working on a new React-Redux tutorial that will teach the React-Redux hooks as the primary approach, based on the "UI and React" page in the Redux docs "Fundamentals" tutorial.
