Good morning. It's September 11th, and today's commits tell a story about cache correctness under pressure.
The biggest thread runs through durable use-cache. Niklas Mischkulnig shipped a wrapper refactor in PR 98559, walking back part of an earlier approach because it broke error stack traces. That sets up a companion fix, PR 98558, for a nastier bug: environment variables changing between cache warmup and final…
The second theme is static shell and navigation correctness. Hendrik Liebau's PR 98512 fixes a mismatch between what "next dev" validates and what production actually builds for partial static shells with dynamic route segments — dev was flagging errors that production correctly allowed. His companion fix, PR 98511,…
On the tooling side, Sebastian Silbermann removed two broken CI pipelines — the Turbopack test manifest job, unused since PR 81170, and the Test Examples workflow, which had been silently failing due to a Playwright version mismatch. That's overdue cleanup, not new capability, but it reduces false signals in CI.
Worth a mention: Jimmy Miller's PR 97203 makes Turbopack lazily compile client-side dynamic imports in development, deferring work until the browser…
