CSS

• Unsere experimentelle Implementierung der CSS Schriftarten Level 3 schreitet voran. Neu implementierte Funktionen sind:
  • Der Fallback Algorithmus von font-variant-position, erstellt synthetische Alternativen für fehlende Glyphen, basierend auf den subscript and superscript metrics supplied by the font (Bug 1024804).
  • Das layout.css.font-features.enabled wurde entfernt, was beudeutet, dass die folgenden Eigenschaften standartmäßig aktiviert sind :
    • The CSS Font Level 3 version of font-variant which is now a shorthand property.
    • The longhand properties font-variant-caps, font-variant-numeric, font-variant-position, font-variant-east-asian, font-variant-ligatures, and font-variant-alternates.
    • The properties font-kerning and font-synthesis
    • The properties font-feature-settings and font-language-override are unprefixed. The prefixed version are still available for some time to ease transition.
• To reflect the latest specification changes, the value auto has been renamed in main-size on the flex-basis property. The shorthand flex keep an auto value, but it is a synonym of 1 1 main-size (Bug 1032922). The value used for the longhand flex-basis when omitted in the shorthand is now  0%, and the one for flex-growth is now 1, both different than their initial value.
• The value auto has been added to min-width and min-height with a different behavior than the last time (Bug 984711 and Bug 1015474).
• An experimental implementation, disabled by default, of the filter functional values of the filter property have been implemented. It is controlled by the layout.css.filters.enabled pref. (Bug 948265)

HTML

Keine Veränderungen.

JavaScript

• The ES6 syntax for computed property names on object literals has been implemented (Bug 924688).
  • This includes getter and setter method names as well (Bug 1048384) and can also be used with destructuring.
• The ES6 shorthand syntax for defining methods on objects has been implemented (Bug 924672).
• The ES6 Object method Object.assign() has been implemented (Bug 937855).
• ES6 template strings and the String.raw() method are now supported (Bug 1038259, Bug 1039774).
• A new ES6 object WeakSet has been added (Bug 792439).
• ES6 Symbols (only available in the Nightly channel) have been updated to conform with recent specification changes (Bug 1042602):
  • When trying to convert a symbol to a number, a TypeError will be thrown now.
  • When using loose equality, Object(sym) == sym returns true now.
• The experimental TypedArray.prototype.move() method (only available in former Nightly and Aurora channels) has been replaced with the now implemented standard ES6 TypedArray.prototype.copyWithin() method (Bug 1021379).
• In strict mode, setting a duplicate property name in object literals will no longer throw a SyntaxError as per ES6 specification (Bug 1041128).

Interfaces/APIs/DOM

• The Element.matches() method has been added; it does what the non-standard mozMatchesSelector() was doing (Bug 886308).
• The searchParams property has been added to the Location interface, available via the document.location and window.location properties (Bug 1037715).
• The Performance.now() method is now available to Web workers (Bug 908390).
• The non-standard interface MozNamedAttrMap has been renamed to the standard NamedNodeMap and Element.attributes has been adapted to use it (Bug 1055467).
• The non-standard methods and properties of Window.crypto have been removed (Bug 1030963). Only methods and properties defined in the standard WebCrypto API are left.
