Hey @kaidjohnson thanks for opening this PR! A couple of things:

1. This is going to be a Breaking change, so please open this PR against the release/4.0.0 branch instead of master 🙏

2. Since 4.0.0 wont have a /dist directory lets remove those changes for now

3. Lets move redux from dependencies to devDependencies in package.json and then add redux as a peer dependency too:

  "peerDependencies": {
    "redux": "^3.0.0"
  },

4. Instead of having it as globals let make it part of externals you can checkout rollups guide on peer Dependencies.

5. You will need to add the externals to the umd build, however since we moved the dependency to peerDependencies it will break es/cjs builds, so you would have to modify that external to accept what it currently does + redux.

6. We are going to start enforcing conventional commits (chore: setup standard-version #180, chore: lint commit messages #181) so please change your commit to follow the standard.
   Eg: something like:

chore(build): Make redux a peerDependency

BREAKING CHANGE: Redux is not going to be part of the umd bundle anymore

Let me know if you have any questions or need help with any of the points stated above.

Looks like release/4.0.0 already includes redux as an external, so the issue should be resolved already on that branch. Fantastic! And thanks for the quick response :)
