v5.1.0

The biggest fix is for connect() being used with React's newer forwardRef, memo, and lazy APIs.

We also have begun a complete rewrite of our docs for React Redux. Check them out! Many thanks to those who contributed: @markerikson, @sveinpg, @wgao19, @BTMPL, @pyliaorachel, @dagstuan, @Kerumen, and @carloluis (sorry if I forgot someone!). Docs are a great way to get started contributing to open source, so open a PR today! Check #1001 to see what else needs to be done.

We're also looking at overhauling Redux's documentation. Check out reduxjs/redux#2590 for the latest there.
