v4.2.1

This bugfix release removes the isMinified internal check to fix a compat issue with Expo. That check has added in early 2016, soon after Redux 3.0 was released, at a time when it was still less common to use bundlers with proper production build settings. Today that check is irrelevant, so we've removed it.

What's Changed

• Remove minified check by @trajano in #4454
