- Use the `willUnload` property to find out if the navigation will result the app being unloaded (full page reload/closing/leaving to another page). ([#6813](https://github.com/sveltejs/kit/pull/6813))
- `__data.json` requests now use the Vary header, which allows one cached response for each variation of the x-sveltekit-invalidated header, ensuring we cache matching responses for all invalidation scenarios ([#7532](https://github.com/sveltejs/kit/pull/7532))
- Linking to `<a name="hash">` tags is now supported ([#7596](https://github.com/sveltejs/kit/pull/7596))

- Throwing redirects in the `handle` hook is now supported ([#7612](https://github.com/sveltejs/kit/pull/7612))
- A fallback component will now be added automatically for layouts without one ([#7619](https://github.com/sveltejs/kit/pull/7619))

- The new `preload` function within the `resolve` hook determines what files should be added to the <head> tag to preload it ([Docs](https://kit.svelte.dev/docs/hooks#server-hooks-handle), [#4963](https://github.com/sveltejs/kit/pull/4963), [#7704](https://github.com/sveltejs/kit/pull/7704))
- `version` is now available via `$app/environment` ([#7689](https://github.com/sveltejs/kit/pull/7689), [#7694](https://github.com/sveltejs/kit/pull/7694))
- `handleError` can now return a promise ([#7780](https://github.com/sveltejs/kit/pull/7780))
