Super important improvements! Congratulations to Alex, Ruslan and Moti for bringing it the final mile!

Intersection Observers (Canary) Continuing our expansion of Web APIs in React Native, we've added IntersectionObserver, which allows you write code responding to layout intersections.

Web Performance APIs as stable As introduced in 0.82, React Native now implements new performance APIs from Web, such as PerformanceObserver, performance.mark/measure, and high resolution timings — now enabled by default.

New iOS build options We now offer an experimental flag to compile out the Legacy Architecture, as well as to debug your precompiled binaries on iOS.
