Bumps react-redux from 6.0.1 to 7.2.2.

Release notes

Sourced from react-redux's releases.

v7.2.2

This release allows you to use React Redux with React 17 without a warning when installing. That's about it.

Shameless self-promotion: Check out my new startup, Spaceship 馃殌. We're building the Continuous Delivery system of the future.

Changes

v7.2.1

This release improves useSelector value display in the React DevTools, fixes a potential race condition, and fixes a couple additional minor issues.

useSelector DevTools Display

The React DevTools normally show custom hooks with their inspected name (such as "Selector" for useSelector), and any calls to core hooks inside. This is not always informative, so React has the useDebugValue hook to allow custom hooks to specify what value should be shown instead.

useSelector now calls useDebugValue to specifically show the current selected value instead of its internal hooks usage.

Bug Fixes

This release has a few different bug fixes:

  • A potential race condition when dispatching actions from child components in the commit phase vs selecting data in a parent
  • Removed an excess new object creation when forcing a re-render
  • Our internal prop name for a forwarded ref is now reactReduxForwardedRef to avoid a rare situation where someone else might be passing down a field named forwardedRef
  • Fixed a typo in a useSelector error message

Changes

v7.2.0

This release fixes two bugs, an algorithmic problem with unsubscribing components and a memory leak with connect. It also has optimizations for production bundle size, and adds a couple small improvements to developer readability while debugging.

Bug Fixes

connect in v7 is implemented using hooks, and the hooks usage captures numerous values from the surrounding scope. We received a PR informing us that the way we were capturing these values would likely result in a copy of the first version of its props being kept alive indefinitely.

This memory leak has been fixed by extracting a custom hook that receives all the necessary values as arguments, so that they're not captured via closure.

We also received a PR letting us know that the unsubscribe logic had a quadratic algorithm in it, as removing a subscriber would use an indexOf(listener) check to remove that callback. If there were a large number of subscribers, that line's runtime would increase rapidly, causing slowdowns.

This algorithm has been replaced with tracking subscribers via a linked list, which drastically improves the runtime of this section of the code even with large numbers of subscribers.

Thanks to @鈥媗arrylin28 and @鈥媤urstbonbon for finding these bugs and submitting PRs to fix them!
