Basic SVG support! You can now export documents and shape layers as simple SVG files. SGA: If there are no shape layers in your image, then the SVG export option will be grayed out. Additionally, this is a pure vector export - any bitmap operations like layer filters or masks are ignored for SVG export.
Taptic feedback for snapping guides (requires OS X 10.11 El Capitan or later).
New preference to have a little tick when snapping guides. For those of you without a fancy taptic trackpad, this one is for you. Turn it on under the Guides preferences - "Audible snaps".
If you've got an Illustrator file that has PDF compatibility turned on for it- Acorn will now open it up like it would a PDF file, allowing you to pick what resolution you'd like to open it as.
