Hey Reader,

Reanimated 4 is finally stable - and you can finally use CSS for animations!

In this week’s video, I walk you through the major changes:

• New CSS Animations & Transitions APIs
• How they compare to the old useSharedValue approach
• What to know about compatibility with the New Architecture
• And the new Worklets package that changes how we write animations

Beyond that, we've got a big release from Maestro, a new Drawpad package, and I wrote up some React Native Performance Tips ⚡️

PS: Get ready for Expo SDK 54 - I'll update you on everything important next week!

Keep building & keep shipping.
