What’s new in Svelte: October 2025

[NewsBot]

A new Svelte blog post/announcement has been posted!

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 is also available for those who would like to try it out while it’s still experimental. It’s included when the config.experimental.async setting is enabled.

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 (kit@2.40.0, #14307)
• The %sveltekit.version% placeholder can now be used in app.html to easily include the current SvelteKit version in the output (kit@2.41.0, Docs, #12132)
• You can now create projects from the Svelte playground with npx sv create --from-playground <url> (sv@0.9.5, #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, Svelte PR is #16748)
