+description: 'Svelte CLI Community Add-ons, TypeScript 6.0 support in SvelteKit'
+author: Dani Sandoval

+---
+
+This month we got a ton of improvements to SvelteKit's remote functions, TypeScript 6.0 support and the experimental release of community plugins in the Svelte CLI.
+
+Svelte was also [featured in ThoughtWorks Technology Radar](https://www.thoughtworks.com/radar/languages-and-frameworks/summary/svelte)!
+
+Big month, bigger showcase... so let's dive in!
+
+## What's new in SvelteKit
+
+- SvelteKit now supports TypeScript 6.0 (**2.56.0**, [Docs](https://devblogs.microsoft.com/typescript/announcing-typescript-6-0/), [#15595](https://github.com/sveltejs/kit/pull/15595))
+- `form` fields can now specify a default value using `field.as(type, value)`, reducing boilerplate for pre-populated forms (**2.56.0**, [Docs](https://svelte.dev/docs/kit/remote-functions#form-Fields), [#15577](https://github.com/sveltejs/kit/pull/15577))
+- Remote function transport now uses `hydratable`, enabling richer data types in query results (**2.56.0**, [#15533](https://github.com/sveltejs/kit/pull/15533))
+- Form `submit` now returns a `boolean` to indicate submission validity for enhanced form remote functions (**2.57.0**, [Docs](https://svelte.dev/docs/kit/remote-functions#form-enhance), [#15530](https://github.com/sveltejs/kit/pull/15530))
+- **Remote Function Breaking Changes (2.56.0)**
+  - Client-requested query refreshes must obtain permission from the server ([#15562](https://github.com/sveltejs/kit/pull/15562))
+  - Stabilize remote function caching by sorting object keys ([#15570](https://github.com/sveltejs/kit/pull/15570))
+  - Add `run()` method to queries, disallow awaiting queries outside render ([#15533](https://github.com/sveltejs/kit/pull/15533))
+  - Isolate command-triggered query refresh failures per-query ([#15562](https://github.com/sveltejs/kit/pull/15562))
+  - `requested` now requires `limit` and yields `{ arg, query }` entries rather than validated args ([#15739](https://github.com/sveltejs/kit/pull/15739))
+
+Looking for more details on the many bug fixes and performance optimizations from this month? Check out the SvelteKit / Adapter [CHANGELOGs](https://github.com/sveltejs/kit/tree/main/packages).
+
+## What's new in Svelte and Svelte Dev Tools
+
+- Community add-ons are now available in `sv` as an experimental feature (**sv@0.1.0**, [Docs](https://svelte.dev/docs/cli/community), [#1020](https://github.com/sveltejs/cli/pull/1020))
+- The `sv` and `sv-utils` packages are now separate in the CLI package - leading to a more explicit public API and a deprecation pass for old features (**sv@0.2.0**, [Docs](https://svelte.dev/docs/cli/sv), [#1046](https://github.com/sveltejs/cli/pull/1046))
+- `sv` will now more reliably detect if Vitest v3 is installed when configuring projects (**sv@0.15.2**, [#1073](https://github.com/sveltejs/cli/pull/1073))
+- Types for `TweenOptions`, `SpringOptions`, `SpringUpdateOptions` and `Updater` are now available as exports from `svelte/motion` (**svelte@5.55.0**, [Docs](https://svelte.dev/docs/svelte/svelte-motion), [#17967](https://github.com/sveltejs/svelte/pull/17967))
