First theme is doing more with less memory. Pull request 101344 releases unused capacity in task storage by tightening how lazy fields, aggregation edges, and empty collections hold onto space. On a large test app, total task storage dropped from about 6.5 gigabytes to about 5.6 gigabytes with no CPU regression.…
Second theme is Turbopack correctness at scale. Pull request 101387 fixes module merge order under scope hoisting, so side-effectful modules no longer run early. Pull request 101374 adds an experimental, off-by-default option to defer evaluation of side-effect-free server modules until first use. And pull request…
