 ## What's new in SvelteKit
 - Param matchers allow you to check if a url parameter matches before rendering a page - replacing the need for fallthrough routes for this purpose ([Docs](https://kit.svelte.dev/docs/routing#advanced-routing-matching), [#4334](https://github.com/sveltejs/kit/pull/4334))
 - Explicit redirects can now be handled directly from endpoints ([#4260](https://github.com/sveltejs/kit/pull/4260))
+- `svelte-kit sync` ([#4182](https://github.com/sveltejs/kit/pull/4182)), TypeScript 4.6 ([#4190](https://github.com/sveltejs/kit/pull/4190)) and Vite 2.9 were released - adding non-blocking dependency optimization and experimental CSS source maps in dev mode as well as a number of bug fixes contributed by the SvelteKit team ([#4468](https://github.com/sveltejs/kit/pull/4468))
