Changes for Web developers

CSS

  • The {{cssxref("text-decoration-line")}} property, still prefixed, now consider 'blink' as a valid property, though it doesn't blink the content at all ({{bug("812995")}}).
  • The non-standard {{cssxref("-moz-text-blink")}} property has been removed ({{bug("812995")}}).
  • Support for the {{cssxref("image-orientation")}} property, in its CSS Images & Values Level 4 version, that is with the from-image keyword and EXIF support, has been added ({{bug(825771)}}).

HTML

No change.

JavaScript

No change.

Interfaces/APIs/DOM

  • Make the last argument (doctype) to {{domxref("DOMImplementation.createDocument")}} optional ({{bug(909859)}}).
  • implement the new {domxref("element.classList")}} specification which permits adding/removing several classes with one call ({{bug(814014)}}).

MathML

  • Inconsistent renderings of {{MathMLElement("mmultiscripts")}},  {{MathMLElement("msub")}}, {{MathMLElement("msup")}} and {{MathMLElement("msubsup")}} have been unified and the error handling of these elements has been improved ({{bug("827713")}}).

SVG

No change.
