React's server renderer now supports nested View Transition animations during Suspense reveals, closing a gap that forced SSR apps to choose between progressive enhancement and smooth animations.

In brief

React Fizz now supports nested enter/exit ViewTransition animations on streaming servers. Opens up actual choreographed sequences during server rendering. that's the kind of thing that sounds impossible until someone ships it.
React DOM now scrolls to text siblings of empty Fragments instead of the parent. Small fix, enormous UX win if you've debugged scroll-to-element behaviors in complex layouts.
Fizz's stack overflow recovery now extends to retries. Basically: when streaming chokes on deep recursion, it can now bounce back instead of crashing the whole request.

The Fizz streaming renderer shipped support for nested parentEnter/parentExit View Transitions [1], emitting vt-parent-enter and vt-parent-exit annotations during streaming so the client picks them up correctly on hydration. This matters because Suspense reveals are core to modern SSR patterns, and animations have been out of reach until now. The same PR uncovered a fragile spot in React's fragment handling [2]: when a Fragment has no children, React was only checking HostComponent siblings before scrolling to parents, missing HostText nodes and risking focus landing on document.ownerDocument.activeElement. The fix reuses existing heuristics and hardened the code by encoding state node types explicitly. That same burst of activity exposed a gap in Fizz's stack overflow recovery [3]: the trampoline catches overflows in extremely deep trees and spawns continuation tasks, but retries weren't covered, leaving a TODO test case that just landed in CI. React Native's Flow definitions got the modern Node.js treatment [4] with node: alias support, so prefixed and unprefixed imports resolve to the same types going forward.
