What's new in Svelte: June 2024

Better `bind`s, migration tooling and a new comparison rune

The maintainers have been hard at work getting the Svelte 5 Release Candidate ready for release. In this month's newsletter, you'll find highlights from the pre-release CHANGELOG and a host of items from our community showcase.

Let's dive in!

What's new in Svelte

  • bind: is now disallowed on component exports in runes mode and has much better types to tell if a prop is $bindable (5.0.0-next.113, 114 and 125, Docs, #11238, #11225 and #11498)
  • Tons of work on the migrate tool to make migrating to Svelte 5 syntax easier (5.0.0-next.116, 136 and 137, Docs, #11334, #11659, #11704)
  • MathML is now supported (5.0.0-next.120, Docs, #11387)
  • The Svelte Inspector is now supported (5.0.0-next.125, Docs, #11514)
  • The $ rune lets you compare values or check if an object exists within a deeply reactive object/array (5.0.0-next.134, Docs, #11613)
  • The rootDir compiler option makes filenames relative to simplify development in monorepos or complex folder structures (5.0.0-next.135, #11627)
