v3.0.4

Includes various bug fixes for existing plugins and a new optimization. Also splits removeXMLNS, which removed XLink, into two separate plugins, removeXMLNS and removeXlink.

What's Changed

Default Behavior

• removeXMLNS, no longer removes the XLink (xmlns:xlink) namespace. If that is desirable, you should enable the new removeXlink plugin, which does more while being safer. By @TrySound and @SethFalco in #1535

Bug Fixes

• convertPathData, ignore instances where transform applied via style tag. By @SethFalco in #1830
• inlineStyles, inline properties with the same specificity in the order that they appear in the stylesheet. By @SethFalco in #1831
• inlineStyles, don't remove class or id from node if it's traversed in another CSS selector. By @SethFalco in #1832 and #1836
• Don't trim pre elements in foreignObject. By @SethFalco in #1796
• Don't crash when encountering @-webkit-keyframes in <style> node. By @SethFalco in #1826

SVG Optimization

• convertPathData, convert to z command if going back to initial position, or drop z if redundant. By @KTibow in #1822
• inlineStyles, when inlining a CSS property that's already declared in a presentation attribute of the node, drop the attribute. By @SethFalco in #1829
• removeXlink, new plugin that removes the XLink (xmlns:xlink) namespace and migrates from XLink attributes to the SVG 2 equivalent. Disabled by default. By @TrySound and @SethFalco in #1535
