svg/svgo v3.0.4 on GitHub

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

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

Bug Fixes

Convert Path Commands, ignore instances where transform applied via style tag. By @SethFalco in #1830
Inline Styles, inline properties with the same specificity in the order that they appear in the stylesheet. By @SethFalco in #1831
Inline Styles, 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

Convert Path Commands, convert to z command if going back to initial position, or drop z if redundant. By @KTibow in #1822
Inline Styles, when inlining a CSS property that's already declared in a presentation attribute of the node, drop the attribute. By @SethFalco in #1829
Remove XLink, 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
