What's new in Svelte: October 2023

Reactions to Runes and SvelteKit +server fallbacks

Svelte 5 isn't out yet (you can, however, preview it now), but that doesn't mean we don't get a sneak peek! Most notably are Runes - a simpler way to manage reactive variables in Svelte code. There's lots of links the showcase section for deeper dives on all things Runes, but let's talk about what else been released this month...

What's new in Svelte & Language Tools

What's new in SvelteKit

  • +server.js now has a catch-all handler that handles all unimplemented valid server requests. Just export a fallback function! (1.25.0, Docs, #9755)

That's all for the new features! If you're looking for other patches and performance updates, check out the SvelteKit CHANGELOG. You can also find adapter-specific CHANGELOGs in each of the adapter directories.
