Good morning, it's September 30th, 2026, and this is React Daily.
The throughline today is resilience in streaming server rendering, with two targeted fixes for what happens when the client and server get out of sync.
First, completed segments that arrive after their placeholder is gone. In pull request 37711, the complete segment handler would crash trying to read the parent of a missing node. That can happen when a client render after a failed hydration clears the container, removing streaming nodes that have not finished yet.…
Second, aborted prerenders resuming in the wrong place. Pull request 37710 addresses a case where an abort interrupts a retried render deep inside a tree. The segment was reset to the retry start, but the key path and child index stayed at the inner child, so the resume would render only that child into the…
Outside streaming, two smaller but useful changes. DevTools profiling will now survive client-side route changes, in pull request 37708. Chrome reports soft navigations as navigation events, which DevTools treated as full reloads, clearing state and stopping profiles. It now listens to the committed navigation event…
And the compiler gets a cleanup in…
