Today’s work is dominated by Turbopack build infrastructure for very large apps, with a separate, high-visibility fix to the Next Image sizing warning.
First, scale and memory. A series of changes tied to large App Router builds aims to cut peak memory and main-thread stalls. One open change, PR 101529, returns freed memory to the operating system immediately after project shutdown, after observations of a large generated app staying near twelve to thirteen…
Second, correctness developers will notice. The merged Image fix, PR 101349, reworks the development sizing warning to compare rendered aspect ratio against the loaded image’s intrinsic dimensions, and only when object fit is fill. That removes false positives for correctly cropped images and fractional vector…
Finally, reliability cleanup. Fixes address scope-hoisted imports of missing exports, smarter did-you-mean suggestions that skip already-imported names, unused web-worker URL handling, and a run of flaky-test repairs around navigation, prefetch collection, source maps, and overlay errors.
What’s next: watch the open build-output and memory-release changes, which…
