v0.6.0 - CLI reads from stdin if no input file is passed. - In arc_to_cubic, use the arc's end point as the last bezier segment's end point; they must be exactly the same. - Added round_floats method; do not automatically round in svg_meta.path_segment (#65, #68). - Snap points very near subpath start to the subpath start, to make sure closed paths are really closed. Do a late absolute() in topicosvg to ensure end-point snapping occurs. This means picosvg will now produce absolute coordinates all the time (#73). - Drop 'enable-background' attribute, it's deprecated (#80). - Apply clip paths *after* ungrouping to fix clipped+stroked paths (#77, 82).
