React Native: Inspector Shutdown Hardening and iOS Stall Fix
The dominant pattern is lifetime and shutdown hardening across the inspector, transport, and dispatcher, paired with iOS responsiveness fixes. The highest-impact change caps display-phase work to once per run loop turn, cutting a worst-case main-thread block from about 146 to under 15 milliseconds.

Good morning, it's October 12th, 2026.
The clear signal today is lifetime and shutdown hardening across the inspector stack, alongside a standout iOS performance fix that caps main-thread stalls.
First, inspector and debugger reliability. Commit eec38e3 fixes DevTools staying open but unresponsive after its React Native instance is destroyed, by sending a disconnect when a page is removed and closing the debugger connection with an explicit page-removed reason. Pull request 58996 extends that work, retaining…
Second, iOS responsiveness and interface parity. Pull request 58642 bounds display-phase event handling to once per run loop turn, after finding one animation commit could trigger eleven blocking JavaScript round trips. In testing with a virtualized list, the worst main-thread block fell from about 146 milliseconds…
Finally, smaller developer experience touches: pull request 59007 declares the queue microtask global for TypeScript, pull request 59002 exposes Android 13 line-break controls for CJK text, and commit 0373754 scopes the internal stack-frame filter to the React Native package so unrelated libraries are no longer hidden.
What's next: watch for validation of the new…
