React Native: Cleaning Up Old Assumptions
Today's activity centers on removing dead configuration and closing correctness gaps left over from earlier architecture decisions — from New Architecture flags to rendering edge cases on Android and iOS. Several fixes also tighten validation logic that was silently accepting bad input.

Good morning. It's September 12th, and today's React Native activity is largely about tidying up after the New Architecture transition and tightening validation that's been too permissive.
Start with cleanup. Commit ca2e11a strips deprecated flags off the Default New Architecture Entry Point on Android — Turbo Modules, Fabric, and bridgeless are always on now, so keeping getters like fabric-enabled around was just dead configuration. PR 58488 does the iOS equivalent, removing the unused…
Second theme: validation gaps that let bad input through silently. Commit e0224fd hardens Performance Observer so invalid option combinations — like empty entry types, or entry types paired with buffered — now fail before a native observer is even registered, instead of misbehaving quietly. PR 58496 fixes the same…
Third theme: rendering correctness on both platforms. PR 58490 fixes iOS clipping so non-uniform border radii — like three rounded corners and one square — render correctly instead of UIKit forcing a uniform radius. On Android, PR 58493 and PR 58494 both address the same elevation-and-opacity artifact: shadows…
What to watch: if you call any of the removed New Architecture APIs, update…
That…
