We just published an advisory for CVE-2025-32388, a moderate severity XSS vulnerability in SvelteKit. Please update to `@sveltejs/[email protected]`. The vulnerability affects applications that iterate over all search parameters inside a server `load` function. More details in the advisory 👇

you can now use .ts files in the playground: svelte.dev/playground/7... caveat: only supports erasable syntax (www.typescriptlang.org/docs/handboo...). under the hood this uses bloomberg.github.io/ts-blank-spa... (note that typechecking/intellisense are TODO)

If you're using SvelteKit (or Svelte+Vite without SvelteKit) then we recommend updating your Vite version. Note that the vulnerability only exists if you're doing `vite dev --host` (or `server.host: true`) on an untrusted network, which you're probably not. But update anyway

Aside from Advent of Svelte, we've also been shipping a bunch of minor bugfixes and improvements. For example, `if` blocks are now treeshakeable — if you have a condition that can be known statically, like `{#if BROWSER}`, then dead code will be eliminated by a minifier
