+description: 'Improved Remote Functions, sv create from playgrounds and experimental async SSR'
+author: Dani Sandoval
+authorURL: https://dreamindani.com
+---
+
+There were lots of improvements to remote functions this month - including new batching tools and improved performance via lazy discovery. For more info, check out the Docs and PR links in each bullet. Async SSR also has a new config flag for those who would like to try it out while it's still experimental.
+
+We've got a hefty showcase this month too, so let's dive in!
+
+## What's new in Svelte, SvelteKit and Svelte CLI (sv)
+
+- The `event` property is now included on popstate, link and form navigation (**[email protected]**, [#14307](https://github.com/sveltejs/kit/pull/14307))
+- The `%sveltekit.version%` placeholder can now be used in `app.html` to easily include the current SvelteKit version in the output (**[email protected]**, [Docs](https://svelte.dev/docs/kit/project-structure#Project-files-src), [#12132](https://github.com/sveltejs/kit/pull/12132))
+- You can now create projects from the from the Svelte playground with `npx sv create --from-playground <url>` (**[email protected]**, [#662](https://github.com/sveltejs/cli/pull/662))
+- Experimental async SSR is available in Svelte v5.39.3 and SvelteKit v2.43.0 or higher. You can opt-in via the `experimental.async` option. When this is enabled, it's possible to use `await` anywhere in your app, without wrapping it in a boundary with a pending snippet. You can find more information in the SvelteKit PR ([#14447](https://github.com/sveltejs/kit/pull/14447), Svelte PR is [#16748](https://github.com/sveltejs/svelte/pull/16748))
+
+### Remote Functions
+
+- The remote function `query.set()` can now be called on the server and `query.refresh()` promises will now be automatically resolved on the server (**[email protected]**, [Docs](https://svelte.dev/docs/kit/remote-functions), [#14304](https://github.com/sveltejs/kit/pull/14304), [#14332](https://github.com/sveltejs/kit/pull/14332))
+- `query.batch` has been added to remote functions - letting you batch requests that happen within the same macrotask (**[email protected]**, [Docs](https://svelte.dev/docs/kit/remote-functions#query.batch), [#14272](https://github.com/sveltejs/kit/pull/14272))
+- Lazy discovery of remote functions improves detection and tree shaking for functions defined in `node_modules` (**[email protected]**, [#14293](https://github.com/sveltejs/kit/pull/14293))
+- Remote form functions have been enhanced with schema support, `input` and `issues` properties (**[email protected]**, [Docs](https://svelte.dev/docs/kit/remote-functions#form), [#14383](https://github.com/sveltejs/kit/pull/14383))
