Next Js Daily: Cache Components Hardening and a Turbopack Deadlock Fix
A cluster of PRs from David Ilie tightened up edge cases in Cache Components around dynamic params, route handler prerendering, and error handling, while Turbopack landed a fix for a real deadlock in its task scheduler. Several documentation corrections rounded out the day.

Good morning, it's August 9th. Here's your Next JS briefing.
Today's biggest signal is a concentrated push to harden Cache Components, alongside a serious concurrency fix in Turbopack.
Start with Cache Components. Several PRs from David Ilie close gaps in how prerendering behaves. PR 96987 adds support for "dynamic params false" so it actually works with Cache Components across pages, layouts, and route handlers. PR 96979 stops a route handler's prospective prerender the moment it reads…
Related: PR 96994 ensures that if page regeneration from a stale cache throws, users see the app's actual global error page instead of a raw plain-text five-hundred — keeping error UX consistent even when caching fails.
Second theme: concurrency correctness in Turbopack. Commit fb3535d fixes a real deadlock in the "scope and block" scheduling primitive — jobs were sometimes assigned exclusively to worker threads that could get starved on constrained runtimes, causing builds to hang indefinitely. The fix routes every job through one…
Smaller but useful: PR 96999 fixes a Turbopack build crash when a traced file path is actually a symlinked directory, and PR 96985 improves image optimizer error messages…
