vNext and Layouts?

I started looking at the possibility of updated an app from v1 to v2. I don’t see any documentation on how to handle Layouts in v2. Are layouts supported in v2?

Could you elaborate what you mean by layout?

I think Brian is asking about router layouts: Router Configuration | Aurelia

Sorry, been away for a while. Yes exactly, router layouts.

I found this vNext router documentation when searching for “layout”.
Maybe you can a clue from there:

The <au-viewport> element is where all of the routing magic happens, the outlet. It supports a few different custom attributes which allow you to configure how the router renders your components. It also allows you to use multiple viewports to create different layout configurations with your routing.
