+### New from Sapper!

 Sapper 0.28.9 just came out. The highlights from it include much better support for CSP nonces, asset preload support for exported pages, and error details are now available in the `$page` store on error pages.
 
 In addition, Sapper's CSS handling has been rewritten over the course of recent releases in order to fix existing CSS handling bugs, refactor the CSS handling to occur entirely within a Rollup plugin, and remove the need internally to register CSS in the routing system. Congrats and thank you to the folks working on Sapper for all their solid work!

 Sapper got some new types in its `preload` function, which will make typing easier if you are using TypeScript. See the [Sapper docs](https://sapper.svelte.dev/docs#Typing_the_function) 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**)
