Good morning, it's August 12th, 2026, and this is Next.js Daily.
The clearest signal today: several long-standing correctness bugs in routing and runtime initialization got fixed, and they share a common root cause — state that was assumed static but wasn't.
Start with optimistic routing. Andrew Clark's PR 97128 fixes an infinite prefetch loop triggered by a specific combination: a proxy rewriting URLs for hidden-locale i18n, plus a fully dynamic catch-all route. The router kept retrying prefetches without checking whether the response actually matched what it expected.…
On the Turbopack side, Josh Story's PR 97215 fixes a runtime initialization race where the shared browser runtime could execute before any async chunk existed, silently stalling client bootstrap and hydration. Similarly, PR 97194 from SnowingFox cleans up a case where deleted App Router routes left stale manifest…
Caching showed up twice too. Luke Sandberg's PR 96941 trims how many old Turbopack cache versions get retained during local development, adding a three-day TTL to curb disk usage. Separately, woohyun-park's PR 97175 addresses stale exports from optimized local barrel files — useful for installed packages,…
