v0.27.0

New features:

• Gradients are supported, as long as you're using Prawn 2.2.0+

Fixes:

• element's width and height now default to 100% as per spec and modern browser implementation
• Better error handling for invalid paths
• Don't 'fill' when drawing a single-dimensional line; this renders wrongly in Adobe Acrobat
• Allow generic font names to be mapped

Constraints:

• Minimum ruby version has been bumped up to 2.1.0.
