Next.js Daily: Turbopack's Efficiency Push and the Instant Navigation Insights

Good morning. It's July 8th, and this is Next.js Daily.
The clearest throughline in the codebase today is Turbopack getting smarter about doing less work. Luke Sandberg landed a trio of related changes: PR 95137 skips a persistence cycle when too little compilation work has happened to justify it, PR 95213 adds an "auto" eviction mode so the cache doesn't restore and…
The second theme is the Partial Prefetching insight system maturing. Aurora Scharff's PR 95365 adds a new Instant insight that fires when a route reads params or search params outside Suspense, blocking the shared App Shell extraction, with two fix paths: stream it or explicitly allow a blocking route. A same-day…
Rounding out the day: React was upgraded again in PR 95581, and the CI team, led by Benjamin Woodruff, split up two of the slowest test suites in PRs 95553 and 95555 to reduce retry cost.
What to remember: if you're touching cache-related Turbopack config, expect new eviction and persistence thresholds to change default behavior. And if you're building routes under Partial Prefetching, the insight system is actively being tuned — expect wording and rule pages to keep shifting.
That's the briefing. Back tomorrow.
