Next.js 16.3.0 Turbopack build fails on Linux distributions with glibc 2.28 because @next/swc-linux-x64-gnu is compiled against GLIBC_2.29; Webpack fallback works but is not automatic.
The @next/playwright instant() helper removes the next-instant-navigation-testing cookie for all origins in a shared Playwright BrowserContext, instead of only the application URL it is controlling. This breaks multi-origin test scenarios where app B's testing cookie is deleted when instant() is called for app A.
Batching router.prefetch calls for multiple slugs of a PPR route in the same tick causes the first-scheduled sibling to be deferred by the 4-request bandwidth cap. When bandwidth frees, the sibling incorrectly resolves against the fallback route entry populated by other completed prefetches instead of fetching its own per-URL segment. Subsequent prefetches become permanent no-ops, forcing full dynamic navigation for the affected slug.
