Good day, it's July 5th, 2026, and this is Next.js Daily.
The clear thread today is Cache Components maturing on two fronts: correctness and configuration, while a separate effort quietly lays groundwork for faster dev refreshes.
First, correctness. Dan Abramov's PR 95485 brings static export support to Cache Components, surfacing uncached data and dynamic API usage as explicit errors in both dev and prod, rather than letting them fail silently in an exported build. Companion PR 95493 fixes a subtler bug: when developers set cache life…
Second, dev-server responsiveness. Hendrik Liebau's PR 95462 introduces a new experimental flag, server components HMR cancellation, as pure plumbing — no behavior change yet, defaulting to off. It threads through the runtime config, the edge and Node render paths, and CI test shards, setting the stage for PR 95486,…
A smaller but practical fix: PR 95497 stops Turbopack's persistence layer from trying to fsync a read-only directory handle on Windows, which was silently disabling on-disk caching and memory eviction for every dev session on that platform. And PR 95498 tightens up import.meta.glob so parent-relative patterns…
What to remember: if you use…
