 * Masks! The `png` and `svg` commands can be used as if they are a mask, so you can color the icon with any color you like. Can be handy for switching to black-and-white, or for reusing the same image but different colors across cards.
 * Gradients! Can now specify linear or radial gradients anywhere you specify colors. See README and `samples/gradients.rb` for more details.
 * Number padding! `save_png` will now pad zeros on the filenames for friendlier sorting. You can also specify your own with `count_format` using the classical format string from Ruby's `Kernel::sprintf` (mostly just C-style format strings). Default: `'%02d'. The `prefix:` option is still there too.
