Sketch 90

What's new in this version:

New:
- Overlays in prototypes: You can now turn any Artboard into an Overlay and create interactions like sheets, popovers and modals in your prototypes. You can set the position of an Overlay relative to the screen it appears on or the layer that links to it. You can even ‘stack’ multiple Overlays, choose how they interact with each other, apply background styling, and even block background interactions. You can view prototypes with overlays on the Mac, web and our new iPhone app (but they will not work in the Mirror).
- Prototyping improvements: Along with Overlays, we’ve added a Prototype tab to the Inspector for all Prototyping-related controls. Switch to this new tab to see all prototype interactions in a document. Switching back to the Design tab will hide them until you select a layer. When you switch to the Prototype tab and select a layer, you’ll see a new + icon instead of the middle-right grab handle, click and drag on this to start creating a new prototype interaction.
- Auto-download Libraries: You can now set Libraries to automatically download whenever an update is available, so you can skip to the good part (reviewing and updating your Components). You’ll find the option for this in the Libraries Preferences pane.

Improved:
- You can now drag images into Sketch and drop them onto existing image layers, or layers with image fills, to replace them
- We’ve improved the how we handle dashed outside borders as well as the PDF export quality of outside borders
- You can move your selection between documents in the Workspace window with the arrow keys on your keyboard
- You can now apply Background Blurs to semi-transparent bitmap image layers
- We've simplified the items for creating and applying masks in both the contextual and menu bar menus
- We now support the webp image format when you add a folder of images as a Data source
- The ⌥ modifier now works when resizing a line too, scaling it from the center like other elements
