Just shipped a 1.8.15 bugfix release. Full release notes here:http://framerjs.tumblr.com/post/98811245487/framer-studio-1-8-15
You can get it by selecting “Check for Updates…” from the Framer Studio menu, or upgrade your current project by selecting File > Update Framer.
Min-Sang Choi I improved the 2d property to get rounded corners and masking to work again. You can now just set layer.force2d and it will work. Will add to the new docs soon.
thanks Koen for the speedy turnaround!
