The release also replicates production prefetch shells for instant navigations during development, narrowing the gap between dev and production behavior. A companion [canary.67](/release/rel_qJ9bQDtIKckGVviXS6C0d-next-js-v16-3-0-canary-67-fixes-imageresponse-local-fonts-and-navigation) carried identical fixes, while [canary.66](/release/rel_zkad17_KF5VdFnuCiJGt4-next-js-v16-3-0-canary-66-reverts-legacy-ppr-codepaths-adds-prefetching-warning) reverted legacy PPR codepath removal and wired a Partial Prefetching warning into Insights for the dev overlay. Just before that, [canary.63](/release/rel_K4e2_njGlxid12bDU5pZP-next-js-v16-3-0-canary-63-introduces-isr-fallback-shells-for-prefetch-requests) introduced ISR fallback shells served during prefetch requests — a meaningful change for pages that combine ISR with the new caching model. The [canary.61](/release/rel_p0azHEI3VRjZ9CGXTyrtz-next-js-v16-3-0-canary-61-adds-global-opt-in-for-cached-navigations-runtime) release added a global opt-in for the runtime stage of Cached Navigations and enabled static prerendering of metadata image routes under Cache Components, while also removing legacy PPR codepaths entirely. Meanwhile, [canary.65](/release/rel_zkX6bXqDOvipFGmXpw0j5-next-js-v16-3-0-canary-65-keeps-resolved-cache-life-for-zero-memory-caches-in) fixed an edge case where `cacheMaxMemorySize: 0` caches were losing their resolved cache life in dev, and [canary.62](/release/rel_Z6MOgE9HHaqFWvq0roO8E-next-js-v16-3-0-canary-62-fixes-false-positive-cache-components-detection) corrected a false-positive detection of `export const dynamic` in Cache Components. ### Expo expands device support [Expo Orbit v2.8.0](/release/rel_ox07uaKiz8O3mIJ73X_tI-v2-8-0) added support for physical iPhones on both Windows and Linux, closing a long-standing gap for developers who test on Apple hardware outside macOS. It also introduced Wi-Fi pairing for Android devices, streamlining wireless debugging. Separately, the [EAS CLI v20.4.0](/release/rel_Yg1oJxZ6q_ENhZQlTFA8K-v20-4-0) added a `observe:session` command for inspecting events by session ID and fixed a channel-auto-creation bug that blocked `eas update --channel` when the channel had no branches. [Maestro testing](/release/rel_0-6uyysLGio2wz-YQSz7z-maestro-testing-insights-clearer-results-and-faster-retries) gained a new insights dashboard that visualizes test-run history across the team, making flaky test identification and regression tracking more accessible. ### SvelteKit and Svelte patch releases [SvelteKit 2.67.0](/release/rel_f8iQYDMnqhnpNj3UnzQNn-sveltejs-kit-2-67-0) added `prerender.handleInvalidUrl` to give developers control over which invalid URLs halt prerendering, and fixed optional form schema fields for projects using `exactOptionalPropertyTypes`. The [adapter-node 5.5.6](/release/rel_d7ZIz3LngIr-pWKsDtI8L-sveltejs-adapter-node-5-5-6) resolved a circular dependency between server initialization and hook retrieval that caused app crashes on startup, and corrected root directory resolution on the server. Svelte [5.56.4](/release/rel_luYsH4CMBmjFbpva90JjF-svelte-5-56-4) fixed three reactivity issues: `{@const}` declarator end positions now include wrapping parentheses, the `searchParams` subscriber no longer fires needlessly when only the URL path changes, and optional parameters in `
