Good morning. This is your Next.js weekly recap for June 1st through 8th, 2026.
50 pull request activity items and 30 additional commits this week focused on performance predictability and memory efficiency.
The headline story is Partial Prefetching becoming a configurable global feature. Previously experimental behavior is now controllable through a new partial prefetching config option. The default Link behavior now prefetches only App Shells rather than full page data, making the performance cost model more…
Turbopack saw substantial memory optimization work this week. The effects eviction system was completed, enabling proper memory cleanup for build outputs that previously accumulated in RAM during long development sessions. The new three-phase state machine handles effect emission, capture, and application with…
React integration remained active with two version upgrades and debugging improvements. The React debug channel now persists through IndexedDB rather than session storage, reducing hydration blocking. Node streams became the default configuration, streamlining the development pipeline.
Infrastructure reliability saw focused attention on cache handler tracing fixes,…
