v2.0.0

🎉 🎉 🎉 Jotai v2 is here! 🍾 🍾 🍾

Backward compatible for JS users without async atoms

Async atom behavior is revisited and changed. TypeScript types are changed and improved.

New Store API

Exposes createStore which opens up new usages. With its power, it can be misused. Let's look for best practice. Feedback is appreciated.

v1.11.0

This includes the pre-release of Jotai v2 API. See RFC #1514.
The v2 API in the pre-release is technically considered unstable, but it's highly recommended to try it before v2. Unless we get any feedback, we don't know what to improve and it will be finalized as is.
Please check the migration guide: https://github.com/pmndrs/jotai/blob/v1.11.0/docs/guides/migrating-to-v2-api.mdx
Feel free to open a new discussion for questions, ideas and so on.

This version has a little breaking change, which is the minimal version of node >=12.20.0 for server side usage.

Full Changelog: v1.10.0...v1.11.0

v1.10.0

We moved integrations to separate packages. They are peer dependencies now and you would need to install them to keep using the features. Eventually, soon they are deprecated and will be removed in jotai v2.0.0. There are no feature differences at this point, so the migration should be easy. Let us know if something goes wrong.

• feat(valtio,zustand,redux,xstate,immer,optics): move integrations to peer deps by @dai-shi in #1573
