We just released a number of security patches across the Svelte ecosystem. If you use SvelteKit, the Vercel adapter for SvelteKit, Svelte, or devalue, you should upgrade. The Vercel OSS Bug Bounty paid out over $14,000 for these reports!

It's official, you can now get paid up to $10,000 for finding security issues in Svelte and SvelteKit! Big thanks to both the security team at Vercel and the Svelte maintainers' group for coming together to make this possible. Learn more: vercel.com/blog/the-ver...

We've released fixes for 5 CVEs affecting the Svelte ecosystem. Please upgrade your apps! Read the post to learn if you're affected: svelte.dev/blog/cves-af...

awed by the svelte community's creativity. no-one does high-concept mischief quite like @kenthropic.com

Advent of Svelte day 3 is all about attachments, the new much more powerful and flexible alternative to actions! And the demo is just so beautiful 🧡 advent.sveltesociety.dev/2025/3

Really thankful today for @rich-harris.dev, @dummdidumm.bsky.social, and all of the rest of the @svelte.dev team. Four years ago, when I discovered Svelte and SvelteKit, I never could have known that working on them full time would be paying the bills.

After way too many rounds of review, `hydratable` is out! This new low-level Svelte API isn’t one you’ll find yourself reaching for often, but it’s extremely useful to libraries. During SSR, function results are serialized alongside your HTML…

Crazy things I somehow managed to get past Rich's review and into @svelte.dev core this year: - Introduced the first yield* into the svelte core - Introduced a variable called `pickled_awaits` that makes me happy every time I see it Stay tuned for whatever other ridiculous things I can get in

vercel recently shipped a feature called workflows, for long-running durable tasks vercel.com/blog/introdu... as of this week you can use workflows with your sveltekit apps. docs here: useworkflow.dev/docs/getting...

I am literally so jazzed to exist in the near future when everything has meshed together and exited the experimental phase.

not my normal content, but i just need you all to know i delivered liquid lacquer to the mask maker in silksong on my first try. this might be my life’s greatest accomplishment and i’m unsure i’ll ever see this high again

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!

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)

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...

h/t @dummdidumm.bsky.social -- insane work getting this put together

Want to make a meaty-but-not-too-big contribution to Svelte Core? We just loosely specced out a new feature, jump in! github.com/sveltejs/sve...

@khromov.se has been doing amazing work in the AI space for Svelte -- what a champion!
