Svelte 4 is out and folks have been building! There’s a bunch of new showcases, libraries and tutorials to share. So let’s get right into it…

What’s new in Svelte (#What’s-new-in-Svelte)The big news this month was the release of Svelte 4.0! You can read all about it in the Announcing Svelte 4 post (/blog/svelte-4). From performance fixes and developer experience improvements to a brand new site, docs and tutorial (/blog/svelte-dev-overhaul)… this new release sets the stage for Svelte 5 with minimal breaking changes.

If you’re already on Node.js 16, it’s possible you won’t see any breaking changes in your project. But be sure to read the migration guide (/docs/svelte/v4-migration-guide) for all the details.

For a full list of all the changes to the Svelte compiler, including unreleased changes, check out the CHANGELOG (https://github.com/sveltejs/svelte/blob/master/packages/svelte/CHANGELOG.md).

What’s new in SvelteKit (#What’s-new-in-SvelteKit)This month there were lots of awesome bug fixes (https://github.com/sveltejs/kit/blob/master/packages/kit/CHANGELOG.md), so be sure to upgrade to the latest version! There are also a few new features to mention:

• The new event.isSubRequest boolean indicates whether this is a same-origin fetch request to one of the app’s own APIs during a server request (1.21.0, Docs (/docs/kit/@sveltejs-kit#RequestEvent), #10170 (https://github.com/sveltejs/kit/pull/10170))

• A new config option, config.kit.env.privatePrefix will set a private prefix on environment variables. This defaults to ‘’ (1.21.0, Docs (/docs/kit/configuration), #9996 (https://github.com/sveltejs/kit/pull/9996))

• VERSION is now exported and accessible via @sveltejs/kit. This can be used for feature detection or anything else that requires knowledge of the current version of SvelteKit (1.21.0, Docs (/docs/kit/@sveltejs-kit#VERSION), #9969 (https://github.com/sveltejs/kit/pull/9969))

For adapter-specific changes, check out the CHANGELOGs in each of the adapter directories.
