Full Changelog: v4.0.0-rc.0...v4.0.0-rc.1

v4.0.0-rc.0

Long-awaited zustand v4!

We started working on #550 at Aug 31 2021. It's been more than 7 months!

Release status

Although this release is v4.0.0-rc.0, we treat this as a normal release. While we might make some changes before the final one, the stability of this release should be same as other releases like v3.7.*.

No breaking changes in JavaScript API

Most notably, this release is backward compatible with the latest v3 API. Some features deprecated in v3 are removed in v4. It's highly recommended to update to latest v3, before upgrading to v4, and check any deprecation messages.

Big rewrite in TypeScript

Zustand code in JS is surprisingly small, and its value is actually in TypeScript. Although it is very tricky to support mutation nature of zustand middleware, @devanshj did a great job to support types as much as possible. There are some breaking changes in types from v3. Please refer ./docs/typescript.md and ./docs/v4-migration.md.

Your feedback is necessary

As always, feedback is welcome, and even necessary this time because otherwise nothing happens. Please try v4 and open issues and discussions (discussions are preferable if you are not sure which).

Full Changelog: v3.7.0...v3.7.1

v3.7.0

This release is to prepare for v4 release, which will include some breaking changes. Especially typing store with middleware will be changed.

It also fixes some small typing issues and improves UMD/SystemJS bundling. Oh, and last but not least, vite users don't need to set NODE_ENV anymore.
