## Source excerpt

Welcome back to the "What's new in Svelte" series! This month, we're covering new features & bug fixes, last month's Svelte Summit and some stand-out sites and libraries... New features & impactful bug fixes Destructuring Promises now works as expected by using the {#await} syntax (3.29.3, Example) Slot forwarding (released in 3.29.0) should no longer hang during compilation (3.29.3, Example) Better typings for the get function in svelte/store and on lifecycle hooks (3.29.1) What's going on in Sapper? Sapper got some new types in its preload function, which will make typing easier if you are using TypeScript. See the Sapper docs on how to use them. There also were fixes to preload links in exported sites. Route layouts got a few fixes too - including ensuring CSS is applied to nested route layouts. You can also better organize your files now that extensions with multiple dots are supported. (0.28.10) For all the features and bugfixes see the CHANGELOGs for Svelte and Sapper. Svelte Summit was Svelte-tacular! Rich Harris demoed the possible future of Svelte development in a talk titled "Futuristic Web Development". The not-yet-public project is called SvelteKit (name may change) and will bring a first-class developer experience and more flexibility for build outputs. If you want to get the full sneak-peek, check out the video. 17 speakers made the best of the conference's virtual format... From floating heads to seamless demos, Svelte developers from every skill level will find something of interest in this year's YouTube playlist Community Showcase Svelte Lab showcases a variety of components, visualizations and interactions that can be achieved in Svelte. You can click into any component to see its source or edit it, using the site's built-in REPL svelte-electron-boilerplate is a fast way to get up and running with a Svelte app built in the desktop javascript framework, Electron React Hooks in Svelte showcases examples of common React Hooks ported to Svelte. gurlic
