Good morning. This is your Next.js Daily weekly recap for March 8th through 15th, 2026.
Thirty-six pull requests merged with 99 additional commits this week, delivering substantial performance and infrastructure improvements.
**Major Features**
The team shipped prefetch inlining with size-based hints, generating bundling decisions at build time to optimize segment loading. This includes server-side infrastructure for measuring gzip sizes and deciding which segments should be bundled versus fetched separately.
Partial fallback handling received significant upgrades. The system now promotes generic shells only to the most specific prerendered version rather than jumping directly to fully concrete routes. A new `remainingPrerenderableParams` field limits partial fallback upgrading to shells that can still benefit from…
Scroll restoration was simplified with a new shared ScrollRef model on CacheNode, replacing the complex segment-path-matching system. This fixes a regression where server action refresh calls incorrectly scrolled pages to the top.
