v4.0.0
Redux 4 is here! 🎉
If you're a React user, this is going to be a lot like going from 15 to 16. Not a lot of user-facing changes, but some interesting improvements under the hood.
The major changes (#1342) are around our TypeScript definitions, bundled CommonJS and ES builds, throwing if you subscribe or getState from a reducer, and a bunch of other smaller things. The full changes are listed below.
Enjoy!
