Good morning, it's August 22nd, and this is Next.js Daily.
The clearest thread today is a push to get partial prefetching behavior exactly right, alongside a broad Turbopack maintenance effort touching bundle size, storage, and code cleanliness.
On the prefetching side, several fixes converge on the same root issue: precedence and edge cases in when content should be included or excluded from prefetches. PR ninety-seven seven twenty-two fixes a bug where a page explicitly setting prefetch to force-disabled could still ship a runtime prefetch stream, because…
On the Turbopack side, Tobias Koppers is landing export-name mangling for smaller bundles, in PR ninety-seven six seventy-two and a follow-up in ninety-seven six seventy-five that extends mangling to the default export. This is opt-in and experimental for now. Meanwhile, Luke Sandberg's storage work — a new options…
Separately, PR ninety-seven six eighty-seven removes generated error codes entirely, citing recurring git conflicts — native error codes and names remain available.
What's next: watch for the mangle-export-names option graduating past experimental, and expect more prefetching precedence fixes as the partial…
