This bugfix release fixes a few minor issues and bits of behavior, including updating the React-Redux peer dep to ^8.0.2 final, stable sorting in createEntityAdapter.updateMany and some initial state handling in createSlice.

Changelog

React-Redux Peer Dep

We'd previously published an RTK build that accepted React-Redux v8 beta as a peer dep (for use with RTK Query). Since React-Redux v8 is out now, we've updated the peer dep to ^8.0.2.

Entity Adapter Updates

Previously, applying updates via createEntityAdapter.updateMany caused sorting order to change. Entities that had the same sorting result should have stayed in the same order relative to each other, but if one of those items had any updates, it would sort to the back of that group. This was due to items being removed from the lookup table and re-added, and since JS engines iterate keys in insertion order, the updated item would now end up compared later than before.

We've reworked the implementation of updateMany to avoid that. This also ended up fixing another issue where multiple update entries targeting the same item ID would only have the first applied.

createSlice Initial State

createSlice now logs an error if initialState is undefined. This is most commonly seen when users misspell initialState. It also has better handling for values that can't be frozen by Immer such as primitives.

RTK Query

Several assorted improvements, including TS types for BaseQuery and checking if the body can actually be safely stringified.

What's Changed

• Add Missing Else to enhanceEndpoints Function

• Check initial state is draftable before using immer to freeze it.

• Check that body isJsonifiable before stringify

• Respect BaseQuery meta types when enhancing

• Throw new error when initial state is undefined

• Rewrite updateMany to ensure stable sorting order

• Bump React-Redux peer dep
