Good morning, it's Monday, October 12th, 2026, and this is React Daily.
The throughline this weekend is renderer safety when work is interrupted, with two narrow fixes preventing a crash and preserving error recovery.
The first case involves two roots on one page and a delayed suspense reveal. If that reveal is throttled and deferred to a set timeout, and the other root commits in the meantime with pending passive effects that synchronously update the first root — through the sync external store hook or a synchronous flush — the…
The second case involves error recovery during server rendering hydration, reported in issue 37809. Previously, the concurrent error recovery logic disabled recovery whenever a synchronous retry reported suspended at the shell, even when the retry had only paused for selective hydration and nothing had suspended in…
What's next is validation on main: watch multi-root suspense behavior and shell hydration with selective hydration and concurrent errors.
