React Native runs fine on Apple TV, which does not have a web browser or web views at all. Please don’t spread false information. Source: I am one of the maintainers of React Native for TV platforms.

Expo SDK 57 will be the easiest upgrade you've ever made. One command. No breaking changes. And boom, you're on React Native 0.86. It's also the first step toward a new release cadence we're considering: optional, non-breaking upgrades between the big SDKs: try.expo.dev/bluesky-sdk57

I’m not sure what that has to do with React Native… in any language it’s pretty easy to build a flow that takes you to a dead end with no return path (not that I’ve ever inadvertently done that 😃)

The 1.6-MW pilot system is among a growing number of initiatives to put solar over waterways. The approach could generate gigawatts of power nationwide.

there's a lot of exciting things going on in SDK 54, but the less exciting changes will hopefully make your upgrade smoother and your everyday DX with dependencies more stable 💕 All kinds of reliability improvements land in SDK 54! small thread about those 🧵
