Summary

This version mainly comes with type improvement for middleware. It's tricky implementation-wise. Please report issues and let's look for solutions or workarounds. It has renamed and deprecated types: UseStore 👉 UseBoundStore A new subscribeWithSelector middleware is added, deprecating the equivalent feature in core.

Migrating to subscribeWithSelector middleware

Previously, you could do this:

const useStore = create(...)
useStore.subscribe(callback, selector, equalityFn)

which is deprecated and replaced with:

const useStore = create(subscribeWithSelector(...))
useStore.subscribe(selector, callback, { equalityFn }) // selector is not optional
