What's new in Svelte: November 2023

Svelte Summit on Nov 11 and better DevEx for all!

Mark your calendars! Svelte Summit Fall is on November 11th. Join us on YouTube and in the Discord for hours of Svelte-focused fun ๐ŸŽฅ

Every month, maintainers within the Svelte ecosystem fix bugs, improve performance and bring new features to Svelte, SvelteKit and the tooling around them. This month's releases brings an improved developer experience with better block folding, inferred types and configuration for use:enhance.

Let's take a closer look ๐Ÿ‘€...

What's new in Svelte & Language Tools

  • Svelte 4.2.2 cleans up a few element-specific features (Release Notes)
  • Extensions 107.12.0 improves block folding for functions, if statements and more (Release Notes, PR)

What's new in SvelteKit

  • Route parameter types will now be inferred from the applicable matcher's guard check ([email protected], Docs, #10755)
  • The new invalidateAll boolean option lets you turn on and off the invalidateAll() form function within the enhance callback ([email protected], Docs, #9476)
  • The output of the project creation wizard will now reflect which package manager you're using ([email protected], #10811)

For a complete list of bug fixes and performance updates, check out the SvelteKit CHANGELOG. You can also find adapter-specific CHANGELOGs in each of the adapter directories.
