4.0.0-beta.0 (2021-07-14)

The primary goal for v4 release is to bring these libraries to newest possible versions:

• react 15.7.0 -> 17.0.2
• react-dom 15.7.0 -> 17.0.2
• redux 3.7.2 -> 4.1.0
• react-redux 4.4.10 -> 7.2.4

We see this release as a breaking change given we will be dropping support for any older versions of React and Redux.
