Why yes, leasing office, I would just love to attend the amazing event you've planned with soda and cheap snacks so that I can be ambushed by whatever insane internet/insurance/dentist's office sales team you've decided to foist upon our complex today

Just merged a relatively significant set of changes to remote functions, especially `query`. It's fairly likely your next upgrade will break your app if you're doing anything decently advanced, but the errors should be pretty helpful/descriptive.

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!

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

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

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)

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...
