That wraps up the major updates! We've covered significant changes, but there's more to explore. We strongly recommend reviewing the full changelog for a detailed understanding before upgrading your projects. Thank you for following along, and happy coding with Effector 23!

`undefined` no longer results in skipped store updates. Want the old behavior back? Simply enable it with `skipVoid: true`. Also, note that if `$store.map(fn)` returns undefined during app initialization, it will now throw an error. 🧵 [8/]

You can read more about function purity in the our Glossary: effector.dev/en/explanation/… 🧵 [7/]

Stricter Function Purity Calling events or effects from functions deemed 'pure' by Effector now triggers runtime errors. Additionally, triggering derived events also results in runtime errors. 🧵 [6/]

The `previous` argument in `.map()` removed We've made a substantial change: the second argument in `$store.map` is now removed. This shift means that derived stores no longer maintain an internal state, leading to cleaner and more predictable state management. 🧵 [5/]

/fork and /scope modules are obsolete The `effector/fork` module has been removed and its functionality is now fully integrated into the core effector package. Plus, `effector-react/scope` is no longer required as all hooks in the main package support scope operations. 🧵 [4/]

New Type Definitions Say hello to `EventCallable`, `StoreWritable`, `UnitTargetable`. These new types distinctly mark writable stores and callable events, streamlining your use of derived units by clearly defining their intended interactions. 🧵 [3/]

Performance Up by 10% Experience a noticeable boost in your business logic workflows. 🧵 [2/]
