Good morning. It's July 13th, and today's commits tell a story of tightening edges around Next dot js's build outputs, especially for the Vercel adapter.
The clearest theme is adapter output correctness. Niklas Mischkulnig landed two related fixes: PR 95264 corrects Pages router 404 handling, where prerendered 404 pages weren't emitting the handler the adapter actually needs for runtime rendering with revalidate or server-side props. PR 95681 fixes a related bug…
Second theme: Turbopack precision. Several PRs target subtle correctness issues rather than features. Harshalj2108's fix for tree-shaking re-exports, PR 95746, addresses severe bundle bloat in libraries like viem and wagmi that use star re-exports — previously bundling hundreds of unused chains. Sokra's PR 95579…
Third, build reliability got attention: Luke Sandberg's PR 95692 makes the experimental TypeScript CLI checker actually stop when a build is interrupted, escalating to a hard kill since the native compiler ignores graceful termination signals. Eps1lon also forked the navigation-testing-lock module in PR 95611 to…
Worth noting: request insights continues its five-part rollout, with PR 93977 adding a diagnose command…
