Fix

Nested TypeScript 'this' parameter handling reverted

A change that made the Rust-based compiler bail out on nested TypeScript 'this' parameters was reverted after landing.

Fix

Cache signal aborts when debug objects retained

Server rendering now aborts the cache signal if debug objects keep references alive, preventing stale cached data.

Fix

Finished renders no longer retained by callers

Both Flight and Fizz were fixed so a completed render can be garbage-collected even if the caller still holds onto a signal.

Fix

Fragment refs detached during mutations

Fragment reference objects are now properly disconnected from the tree when elements are removed or changed.

Fix

Fragment listeners scoped correctly

'once' event listeners on Fragments now fire once per Fragment rather than once per child element.

Fix

Fragment listeners attach to text children

Event listeners on a Fragment ref now also cover committed plain-text children.

Fix

Fragment focus blurs portaled targets

When content rendered into a portal loses its place in the tree, focus is properly blurred.

Fix

Fragment removeEventListener fixed

Removing an event listener from a Fragment no longer accidentally drops other tracked listeners.

Fix

Hidden Activity trees skip metadata hoisting

Metadata is no longer hoisted out of trees hidden by <Activity>, preventing incorrect behavior.

Fix

Conditional use warning enabled experimentally

A warning for conditionally calling the use() hook is now enabled on the experimental release channel.

Fix

DevTools error reporting deduplicated

Duplicate error reports from DevTools are now collapsed so issues aren't reported multiple times.

Fix

Fixed hang updating dehydrated boundary in hidden tree

Updating a server-rendered boundary inside a hidden tree no longer causes the app to freeze.

Fix

Blur focused descendants in Fragment refs

When a focused element inside a Fragment goes away, focus is properly cleared.
