Snyk has created this PR to upgrade redux from 4.0.5 to 4.1.0.

ℹ️ Keep your dependencies up-to-date. This makes it easier to fix existing vulnerabilities and to more quickly identify and fix newly disclosed vulnerabilities when they affect your project.

The recommended version is 2 versions ahead of your current version.
The recommended version was released 21 days ago, on 2021-04-24.

Release notes

Package name: redux

4.1.0 - 2021-04-24

This release shrinks our bundle size via error message extraction, updates several error messages for clarity, and optimizes our list of runtime dependencies.

Overall, version 4.1 shrinks from 2.6K min+gz to 1.6K min+gz thanks to these changes.

Be sure to check out the Redux Toolkit 1.6 alpha containing our new "RTK Query" data fetching APIs! It also includes Redux 4.1 as a dependency.

Error Message Extraction and Improvements

We now extract all of our error messages from production builds in order to save on bundle size, using a technique inspired from React's error code extraction. The error messages will still show as normal in development, but in production they will reference a specific numeric error code and provide a link to a Redux docs page that has the full error message.

An example of this is: https://redux.js.org/errors?code=5 , which shows the "can't subscribe while reducers are executing" error.

The error code extraction saves about 800 bytes out of a production build.

Thanks to @ andrewmcgivery for doing all the hard work on implementing the error extraction!

We've also updated many of our error messages to provide additional details at runtime about what happened, especially runtime type checks such as "actions must be plain objects". They now provide a more specific type for the unexpected value, such as indicating promise or function:

    expect(() => store.dispatch(() => {})).toThrow(
      /the actual type was: 'function'/
    )
<span class="pl-en">expect</span><span class="pl-kos">(</span><span class="pl-kos">(</span><span class="pl-kos">)</span> <span class="pl-c1">=&gt;</span> <span class="pl-s1">store</span><span class="pl-kos">.</span><span class="pl-en">dispatch</span><span class="pl-kos">(</span><span class="pl-k">new</span> <span class="pl-v">Date</span><span class="pl-kos">(</span><span class="pl-kos">)</span><span class="pl-kos">)</span><span class="pl-kos">)</span><span class="pl-kos">.</span><span class="pl-en">toThrow</span><span class="pl-kos">(</span>
  <span class="pl-pds"><span class="pl-c1">/</span>the actual type was: 'date'<span class="pl-c1">/</span></span>
<span class="pl-kos">)</span></pre></div>

Dependency Updates
We've updated the list of runtime dependencies for Redux:

We inlined the symbol-observable polyfill. This shrinks bundle size by a few bytes,
We've removed the legacy loose-envify dependency, which was only ever needed by Browserify users. If you still happen to be using Browserify, please review your build settings and see if you need to make any updates.
We now explicitly depend on @ babel/runtime to extract some additional helpers out of our bundle. It's likely that your app already is pulling in those helpers anyway, so that removes some potential duplication.

Typing Tweaks
We've merged fixes for a couple edge cases in the 4.x TS typings related to state types.
Changes

v4.0.5...v4.1.0

4.1.0-alpha.0 - 2021-04-04
This pre-release for 4.1.0 shrinks our bundle size via tooling updates, and updates several error messages for clarity. This is all the changes we plan to have for 4.1, so if feedback looks good, we'll release 4.1.0 shortly.

Changelog Summary

The 4.1.0 release will have a more complete changelog, but summarizing:
- Shrinks our bundle sizes by extracting error messages from production builds and replacing them with error codes (similar to React). Thanks to @ andrewmcgivery for implementing this!
- Inlines the symbol-observable polyfill
- Drops the legacy loose-envify dependency
- Externalizes the @ babel/runtime helpers
- Fixed a TS typedef to work better with TS 4.3
We've also updated the error messages to clarify what's happening, provide more details when runtime type checks fail, and link to relevant documentation.

v4.0.5...v4.1.0-alpha.0
4.0.5 - 2019-12-24
This release includes a memory leak fix, and a fix for removing reducers with replaceReducer and combineReducers.

There are also some TypeScript changes, which require version 3.5 or higher. This also removes our DeepPartial type, which wasn't intended to be a public API. If you need this type, you can find an equivalent of likely higher quality in the utility-types package.

Speaking of TypeScript, we are done with converting the code to TypeScript on master and are looking to get some TS improvements in before launching 5.0. If you're interested in helping, feel free to submit a PR with anything you'd like to contribute.

Changes
- Clear current listeners on store unsubscribe (#3475 by @ dmitrysteblyuk)
- Fix for combineReducers when replaceReducers removes a reducer (#3490 by @ anubhavgupta)
- TypeScript: Add strict type inference overload for combineReducers (#3484 by @ ChrisAckerman)
- TypeScript: Preloaded state is now selectively partial (instead of deeply partial) (#3485 by @ ChrisAckerman)
