Good morning, it's Thursday, November 12th, 2026, and this is React Daily.
Volume today is dominated by a coordinated DevTools security cleanup, while the sharpest runtime fixes close two server streaming leaks.
First, the cleanup. Nearly twenty open pull requests update or remove vulnerable DevTools dependencies. For example, PR 38215 raises webpack past DOM clobbering and related advisories, and PR 38209 moves the development server from version four to five to clear a cluster of high-severity issues. PR 38204 moves…
Second, streaming reliability. PR 38186 fixes Flight streams hanging after a synchronous abort. If a render or prerender aborted while serializing async values, tasks for iterables, streams and large binary objects registered abort listeners too late, leaving reads pending and the stream open forever. The fix checks…
