Acorn 6.6
The main new features are with the Shape Processor. If you’re not already familiar with the shape processor, it’s a neat ability Acorn has to take shapes on vector layers and pipe them through a series of actions, similar to how Automator or Acorn’s bitmap filters work. Only instead of working on pixels, the processors will alter the shapes by scaling them or moving them around, or changing colors or blend modes. There’s even a processor which will generate shapes for you—so if you want your canvas to fill up with hundreds of stars, you can do that.
Acorn 6.6 adds new processors which let you set the stroke, fill, and blend mode of your processed shapes. You can now also flip your shapes and even shift colors.
