- fabric.Text has now strokeDashArray support (only native support) - fabric.Text.fill = null should now work - Fix save/restore context in render methods => setLineDash affected drawBorder/drawControls - Add strokeLineCap (default "butt"), strokeLineJoin (default "miter") and strokeMiterLimit (default 10) - Add support for fabric.Object#fromElement for strokeDashArray (and other stroke properties) - Add @default tag to properties (JSDoc 3) - strokeDashArray now only works if stroke property is defined - Add trokeLineCap (default "round"), strokeLineJoin (default "round") to fabric.BaseBrush - Updated unit tests
