+
+<h3 id="CSS">CSS</h3>
+
+<ul>
+ <li>Our experimental implementation of CSS Fonts Level 3 progresses. Newly implemented features are:
+  <ul>
+   <li>the fallback algorithm of {{cssxref("font-variant-position")}}, creating synthetic alternates for missing glyphs, based on the subscript and superscript metrics supplied by the font ({{bug(1024804)}}).</li>
+   <li>The <code>layout.css.font-features.enabled</code> preference has been removed, meaning the following properties have been activated by default:
+    <ul>
+     <li>The CSS Font Level 3 version of {{cssxref("font-variant")}} which is now a shorthand property.</li>
+     <li>The longhand properties {{cssxref("font-variant-caps")}}, {{cssxref("font-variant-numeric")}}, {{cssxref("font-variant-position")}}, {{cssxref("font-variant-east-asian")}}, {{cssxref("font-variant-ligatures")}}, and {{cssxref("font-variant-alternates")}}.</li>
+     <li>The properties {{cssxref("font-kerning")}} and {{cssxref("font-synthesis")}}</li>
+     <li>The properties {{cssxref("font-feature-settings")}} and {{cssxref("font-language-override")}} are unprefixed. The prefixed version are still available for some time to ease transition.</li>
+    </ul>
+   </li>
+  </ul>
+ </li>
+ <li>The value <code>auto</code> has been added to {{cssxref("min-width")}} and {{cssxref("min-height")}} with a different behavior than the last time ({{bug(984711)}} and {{bug(1015474)}}).</li>
+ <li>An experimental implementation, disabled by default, of the filter functional values of the {{cssxref("filter")}} property have been implemented. It is controlled by the <code>layout.css.filters.enabled</code> pref ({{bug(948265)}}).</li>
+ <li>Fixed starting of CSS transitions that start together with changes to {{cssxref("display")}}, {{cssxref("position")}}, {{cssxref("overflow")}}, and similar properties ({{bug(625289)}})</li>
+</ul>
+
+<h3 id="HTML">HTML</h3>
+
+<p><em>No change.</em></p>
+
+<h3 id="JavaScript">JavaScript</h3>
+
+<ul>
+ <li>The ES6 syntax for <a href="/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#Computed_property_names">computed property names on object literals</a> has been implemented ({{bug(924688)}}).
+
+  <ul>
+   <li>This includes <a href="/en-US/docs/Web/JavaScript/Reference/Functions/get">getter</a> and <a href="/en-US/docs/Web/JavaScript/Reference/Functions/set">setter</a> method names as well ({{bug(1048384)}}) and can also be used with <a href="/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#Computed_object_property_names_and_destructuring">destructuring</a>.</li>
+  </ul>
+ </li>
+ <li>The ES6<a href="/en-US/docs/Web/JavaScript/Reference/Functions/Method_definitions"> shorthand syntax for defining methods</a> on objects has been implemented ({{bug(924672)}}).</li>
+ <li>The ES6 <code>Object</code> method {{jsxref("Object.assign", "Object.assign()")}} has been implemented ({{bug(937855)}}).</li>
+ <li>ES6 <a href="/en-US/docs/Web/JavaScript/Reference/template_strings">template strings</a> and the {{jsxref("String.raw()")}} method are now supported ({{bug(1038259)}}, {{bug(1039774)}}).</li>
+ <li>A new ES6 object {{jsxref("WeakSet")}} has been added ({{bug(792439)}}).</li>
+ <li>ES6 <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol">Symbols</a> (only available in the Nightly channel) have been updated to conform with recent specification changes ({{bug(1042602)}}):
+  <ul>
+   <li>When trying to convert a symbol to a number, a <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypeError" title="The TypeError object represents an error when a value is not of the expected type."><code>TypeError</code></a> will be thrown now.</li>
+   <li>When using loose equality, <code>Object(sym) == sym</code> returns <code>true</code> now.</li>
+  </ul>
+ </li>
+ <li>The experimental {{jsxref("TypedArray.prototype.move()")}} method (only available in former Nightly and Aurora channels) has been replaced with the now implemented standard ES6 {{jsxref("TypedArray.prototype.copyWithin()")}} method ({{bug(1021379)}}).</li>
+ <li>In <a href="/en-US/docs/Web/JavaScript/Reference/Strict_mode">strict mode</a>, setting a <a href="/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#Duplicate_property_names">duplicate property name in object literals</a> will no longer throw a <code>SyntaxError</code> as per ES6 specification ({{bug(1041128)}}).</li>
+ <li>In regular expressions (including <code>String.replace</code>), the matched text for a capturing group is now <code>undefined</code> instead of the empty string when that capturing group didn't get consulted because quantifiers prevented its exercise (see {{bug(369778)}} and <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp#Gecko_specific_notes">this example code</a>). Note that due to web compatibility, RegExp.$N will still return an empty string ({{bug(1053944)}}).</li>
+ <li>The ES6 <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator">spread operator</a> is now supported in <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment">destructuring</a> ({{bug(933276)}}).</li>
+ <li><a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment">Destructuring</a> now uses iterator protocol instead of array-like protocol ({{bug(933276)}}).</li>
+ <li><span class="message"><span class="content">{{jsxref("Proxy.revocable()")}} has been implemented</span></span> ({{bug(978279)}}).</li>
+</ul>
+
+<h3 id="InterfacesAPIsDOM">Interfaces/APIs/DOM</h3>
+
+<ul>
+ <li>The {{domxref("Element.matches()")}} method has been added; it does what the non-standard <code>mozMatchesSelector()</code> was doing ({{bug(886308)}}).</li>
+ <li>The {{domxref("Performance.now()")}} method is now available to Web workers ({{bug(908390)}}).</li>
+ <li>The non-standard interface <code>MozNamedAttrMap</code> has been renamed to the standard {{domxref("NamedNodeMap")}} and {{domxref("Element.attributes")}} has been adapted to use it ({{bug(1055467)}}).</li>
+ <li>The {{domxref("Path2D.addPath()")}} method has been added ({{bug(985801)}}).</li>
+ <li>The non-standard <a href="/en-US/docs/Web/API/Device_Storage_API">Device Storage API</a> is now also enabled for privileged apps installed on Android ({{bug(886627)}}).</li>
+ <li>Web Crypto API has been enabled by default ({{bug(1074001)}}).</li>
+ <li>The {{domxref("MediaStreamTrack.stop()")}} method has been added ({{bug(1057955)}}).</li>
+ <li>Our experimental implementation of EME continues. The {{domxref("MediaKeySession.getUsableKeyIds()")}} method has been added ({{bug(1057171)}}).</li>
+ <li>Regarding <a href="/en-US/docs/Web/Guide/API/WebRTC">WebRTC</a>:
+  <ul>
+   <li>an experiment implementation of {{domxref("RTPSender")}} and {{domxref("RTPReceiver")}} working with {{domxref("RTCPeerConnection")}} has landed ({{bug(1032835)}}).</li>
+   <li>application window sharing has been added to {{domxref("Navigation.getUserMedia()")}} ({{bug(1036653)}}) and {{domxref("MediaTrackConstraintSet")}} now supports <code>browserWindow</code> and <code>scrollWithPage</code> allowing to chose the tab of a window that has to be shared without showing the tab chooser dialog ({{bug(1041700)}}).</li>
+   <li><code>"browser"</code> is now an accepted value of MediaSourceEnum, used to define constraints ({{bug(1041493)}}).</li>
+  </ul>
+ </li>
+ <li>For Web Components, event retargeting is now implemented ({{bug(887541)}}).</li>
+ <li>The {{domxref("Headers")}} interface has been implemented ({{bug(1029620)}}). It is controlled by the <code>dom.fetch.enabled</code> preference which is set to <code>false</code> by default.</li>
+ <li>Regarding our experimental implementation of Web Animations, the {{domxref("AnimationEffect")}} interface has been added, with the single {{domxref("AnimationEffect.name")}} property ({{bug(1045993)}}). Web Animations is not activated by default and is controlled by the <code>dom.animations-api.core.enabled</code> preference.</li>
+ <li>CSSOM View smooth scrolling methods have been added: {{domxref("Window.scroll()")}}, {{domxref("Window.scrollTo()")}}, and {{domxref("Window.scrollBy()")}} ({{bug(1022818)}}).</li>
+ <li>The non-standard <code>MozSmsSegmentInfo</code> is no more visible on the global object {{bug(916607)}}.</li>
