This release brings a few changes that, while aimed at making the developer experience better, should have no noticeable impact on your apps.
- In development,
combineReducers()now checks the state shape on every invocation instead of just once. This makes it easy to discover issues like #715 where you post-process the state fromcombineReducers()and then wonder why something you added to it has disappeared after the next action. This change has no effect in production, and you’re unlikely to hit it in development either, as post-processing state from isn't a very common pattern. (, )
