Version 7: Connected components are objects instead functions

[radeno]

With react-redux 6 connected component was returned as function. eg:

ƒ Connect(props)

Instead version 7 returns it as object because react hooks:

{$$typeof: Symbol(react.memo), type: ƒ, compare: null, WrappedComponent: ƒ, displayName: "Connect(Component)", …}

I think this should be noted for developers with PropTypes module for type checking.

i came to report the same thing, it actually breaks react-router for anyone that hasnt made the jump to v4

[timdorr]

This is because we use React.memo on the component. As a workaround, you can set the pure option to false, which comes with a performance penalty.

@timdorr We dont have any contra arguments. But it is breaking change and should be noted

[markerikson]

This is not a breaking change to our public APIs.

As of React 16.6, special component types like React.memo() are objects, not functions. Any code that assumed a React component can only be a function is wrong, and has been wrong since 16.6 came out.

I'll update the release notes accordingly, but this is an incorrect assumption on the part of the other libraries.

We handle this correctly in React Router 5, FWIW.
