+description: "Svelte Summit Spring is coming... and page endpoints are here!"

+
+Just announced: [Svelte Summit Spring](https://www.sveltesummit.com/) will be taking place on April 30, 2022. The 5th Virtual Svelte Conference is [looking for speakers](https://www.sveltesummit.com/#speakers) and [sponsors](https://www.sveltesummit.com/sponsors)... so it's time to dust off those proposals!
+
+Also, some long-requested features were added to SvelteKit this month... including page endpoints! This change in how the `load` function works makes it easier to fetch data required for basic pages, redirect from POST responses and handle 404s and other errors.
+
+More on that and other new features and fixes below!
+
+## What's new in SvelteKit
+- The docs are now searchable and multipage with type definitions and hoverable code examples - Check them out at [kit.svelte.dev/docs](https://kit.svelte.dev/docs/)
+- Page endpoints significantly decrease the boilerplate needed when loading a page ([Issue](https://github.com/sveltejs/kit/issues/3532), [PR](https://github.com/sveltejs/kit/pull/3679), [Docs](https://kit.svelte.dev/docs/routing#endpoints-page-endpoints))
+- Application versioning and update detection support lets you determine what to do when a route fails to load after an app update ([Issue](https://github.com/sveltejs/kit/issues/87), [PR](https://github.com/sveltejs/kit/pull/3412), [Docs](https://kit.svelte.dev/docs/configuration#version))
+- A new option in `npm init svelte@next` will now set up Playwright automatically for testing ([PR](https://github.com/sveltejs/kit/pull/4056))
+
+
+**Breaking Changes**
+- The `target` option is no longer available. Instead, the `init` script hydrates its `parentNode` ([#3674](https://github.com/sveltejs/kit/pull/3674))
+- App-level types now live in the `App` namespace which allows you to type global types like `Stuff` or `Session` ([#3670](https://github.com/sveltejs/kit/pull/3670))
+- `JSONString` is now `JSONValue` ([#3683](https://github.com/sveltejs/kit/pull/3683))
+- `createIndexFiles` has been removed — it is now controlled by the `trailingSlash` option ([#3801](https://github.com/sveltejs/kit/pull/3801))
+- SvelteKit will no longer exclude root-relative external links from prerendering, which will cause 404s if these URLs are intended to be served by a separate app. Use a custom [`prerender.onError`](https://kit.svelte.dev/docs/configuration#prerender) handler if you need to ignore them ([#3826](https://github.com/sveltejs/kit/pull/3826))
+
+
+## New in Language Tools
+- Accessing properties in markups has been improved in the Svelte language tools ([105.12.0](https://github.com/sveltejs/language-tools/releases/tag/extensions-105.12.0)) - working around some known issues with autocomplete ([#538](https://github.com/sveltejs/language-tools/issues/538) / [#1302](https://github.com/sveltejs/language-tools/issues/1302))
