  • Fixed bug in “convertStyleToAttrs” plugin with converting styling properties to non-existent attributes (which are normally removed later by removeUnknownsAndDefaults).

  • New optimization: circular curves now being converted to arcs. A notable improvement for circles within paths.
  • New plugin “minifyStyles” which minifies <style> elments content with CSSO by @strarsis (svgo still doesn't understand its content)
  • New plugin “removeStyleElement” (disabled by default) by @betsydupuis.
  • Fixed issues wuth parsing numbers with exponent fraction (could happen with high precision >= 7).
