Good morning, it's Saturday, November 7th, 2026, and this is Next.js Daily.
The lead signal is weight loss. The production server was loading code it never uses, and a new batch of work strips it out, while Turbopack gets correctness fixes and Cache Components gets a header bug fix.
First, server startup. Contributor Timer opened a series linked to startup profiling, proposing to load dependencies only when needed. In pull request 101323, a route handler using cookies or headers from next slash headers pulled in the full app page runtime, nearly 700 kilobytes of render code it should never…
Second, Turbopack reliability and boundaries. Pull request 101152 fixes a Pages Router HMR bug where adding or removing a re-export left stale content on screen after Fast Refresh reported success. Page entries will now stay whole instead of splitting. Supporting that, 101291 replaces Next.js-specific entry kinds in…
Third, caching correctness and guidance. Pull request 100960 stops pre-rendered Link headers from duplicating on every revalidation with Cache Components enabled, where config headers and preload headers accumulated. Matching docs work in 101224 tells developers to read window dot…
