  • Improved the tutorial experience for easier learning and better support for future content.

Bug Fixes

Is Mask AI supposed to work as a plugin to Lr? Under preferences I can either select GPU or CPU. My installation has defaulted to CPU but I gave a GPU with 4 gig ram on board my iMac. Why has it not selected GPU?
