5.0.0

Svelte CSF 5.0 is here

It brings support for Svelte 5, and major improvements to the Svelte CSF syntax, including

• ✂️ Snippet-based API for stories
• 🔬 Smaller bundle size
• 🛟 Type-safe stories and meta definitions
• 📚 Improved documentation and examples

Please checkout our Migration Guide to upgrade from earlier versions of the Svelte CSF addon. You can use the Legacy API flag to gradually migrate your stories to the new syntax. The biggest breaking change is that it now requires Svelte 5.
