| 8 | +With [Async Svelte](https://github.com/sveltejs/svelte/discussions/15845) and its companion [Remote Functions](https://github.com/sveltejs/kit/discussions/13897) officially out in the world, there's a lot of updates to share! |
| 9 | + |
| 10 | +Be sure to check out the showcase for videos from Rich, Paolo, and Stanislav about all the brand new features in Svelte. |
| 11 | + |
| 12 | +Let's dive into the highlights... |
| 13 | + |
| 14 | +## What's new in Svelte, SvelteKit, Language Tools and CLI (sv) |
| 15 | + |
| 16 | +- Remote functions can be called anywhere in your app, but always run on the server, and as such can safely access server-only modules containing things like environment variables and database clients (**kit@2.27.0**, [Docs](https://svelte.dev/docs/kit/remote-functions), [#13986](https://github.com/sveltejs/kit/pull/13986)) |
| 17 | +- `getAbortSignal` returns an `AbortSignal` that aborts when the current derived or effect re-runs or is destroyed (**svelte@5.35.0**, [Docs](https://svelte.dev/docs/svelte/svelte#getAbortSignal), [#16266](https://github.com/sveltejs/svelte/pull/16266)) |
| 18 | +- A new `parent` property has been added to the `__svelte_meta` properties that are added to elements at dev time - useful for debugging nested hierarchies (**svelte@5.35.1**, [#16255](https://github.com/sveltejs/svelte/pull/16255)) |
| 19 | +- `await` is now supported in components when using the `experimental.async` compiler option (**svelte@5.36.0/extensions@109.10.0**, [Docs](https://svelte.dev/docs/svelte/await-expressions), [#15844](https://github.com/sveltejs/svelte/pull/15844)) |
| 20 | +- There are now types for the `params` prop and `page` attributes in page/layout components (**kit@2.24.0, kit@2.26.0 & extensions@109.10.0**, [#13999](https://github.com/sveltejs/kit/pull/13999) / [#13864](https://github.com/sveltejs/kit/pull/13864)) |
| 21 | +- SvelteKit's `read` now works in edge environments where `fs.readFile` isn't available such as in Cloudflare's workers, Netlify, and Vercel's edge functions (**kit@2.25.0**, [#13859](https://github.com/sveltejs/kit/pull/13859)) |
| 22 | +- The `resolve(...)` and `asset(...)` helpers have been added for resolving paths (**kit@2.26.0**, [#13864](https://github.com/sveltejs/kit/pull/13864)) |
| 23 | +- Support for modern SvelteKit prop typings has been added to VS Code snippets (**extensions-109.10.0**, [#2796](https://github.com/sveltejs/language-tools/pull/2796)) |
| 24 | +- The new `vite.addPlugin` simplifies adding a plugin on various vite config styles (**sv@0.8.20**, [#633](https://github.com/sveltejs/cli/pull/633)) |
| 25 | +- vite-plugin-svelte is out with support for vite7, rolldown-vite and [more](https://github.com/sveltejs/vite-plugin-svelte/blob/main/packages/vite-plugin-svelte/CHANGELOG.md) |
| 26 | + |
