Although I barely write code now, I still run commit and push handful of times, since 15+ tool calls to do it by an agent seems like a waste to me.

Diagnose and debug errors faster with issues and replays from Sentry in Expo With the new Sentry integration in EAS you can view crash reports & session replays for your Expo app deploymentsβ€”so you can fix issues fast, with full context.

Debugging in React Native got easier today.

We now have an official integration with @sentry.io so you can see errors and replays directly in your EAS Deployments.

No more digging through logs or guessing at app state.
