I am literally so jazzed to exist in the near future when everything has meshed together and exited the experimental phase.
today we landed a @svelte.dev feature i'm pretty stoked about — we call it 'forking', and it lets you run state changes offscreen and later choose whether to commit them (e.g. user hovers on a link, preload data in case they click)

Super excited to announce the experimental release of asynchronous SSR in Svelte! github.com/sveltejs/sve...

`await` expressions in your Svelte components can now be rendered on the server, meaning you don't need to render them inside boundaries with a `pending` snippet. Next up, streaming SSR!
Async SSR · sveltejs svelte · Discussion #16784
The Svelte team has been hard at work on asynchronous rendering, with client-side support and remote functions as our first two efforts. It’s time for the third: SSR. Background There are three cor...

It's finally out! SvelteKit users: update your Sentry SDK to 10.8.0 or later to get those nice traces. All courtesy of @ell.iott.dev and @svelte.dev.

(Please let me know if I broke your app in the process)
SvelteKit observability just got 10x better, and we’re here for it
SvelteKit now supports full observability and tracing, with Sentry SDK compatibility from v10.8.0. See how to set up server-side instrumentation.

OpenTelemetry tracing is live in SvelteKit! Huge s/o to @stracke.tech for all the help along the way. SvelteKit can now emit OTEL spans for all of its serverside constructs. It also provides an instrumentation file to easily set up trace exports. svelte.dev/blog/sveltek...
Introducing integrated observability in SvelteKit
SvelteKit apps can now emit OpenTelemetry traces and reliably set up observability instrumentation using instrumentation.server.ts

h/t @dummdidumm.bsky.social -- insane work getting this put together
hard to overstate how excited i am about this RFC — @dummdidumm.bsky.social is doing incredible work. this raises the bar for data fetching in frameworks, and unlocks some very cool new use cases for SvelteKit. we have a lot more ideas that will build on top of this work

@khromov.se has been doing amazing work in the AI space for Svelte -- what a champion!
👀 What if every AI model could have updated Svelte 5 documentation? I created an experimental MCP server, give it a try! It's free and open source.
