+# History of user-visible changes
+
+## 20150202
+
+Support for:
+
+* [ES6 modules](http://www.2ality.com/2014/09/es6-modules-final.html).
+* [Short-hand object
literals](http://ariya.ofilabs.com/2013/02/es6-and-object-literal-property-value-shorthand.html).
+* [Method
definitions](http://ariya.ofilabs.com/2013/03/es6-and-method-definitions.html).
+* ['u' and 'y' RegExp flags](https://mathiasbynens.be/notes/es6-unicode-regex).
+* [Computed property
names](http://people.mozilla.org/~jorendorff/es6-draft.html#sec-object-initializer).
+* [Class statements and
expressions](https://github.com/lukehoban/es6features#classes).
+* [Template strings](http://tc39wiki.calculist.org/es6/template-strings/),
including tagged ones.
+
+The variable `js2-allow-keywords-as-property-names` has been
+removed. Instead we check if `js2-language-version` is 180 or highter.
+
+## 20141115
+
+Support for:
+
+* Unicode characters in identifiers (improved).
+* [Delegating
yield](http://wiki.ecmascript.org/doku.php?id=harmony:generators#delegating_yield).
+* [ES6 numeric
literals](https://people.mozilla.org/~jorendorff/es6-draft.html#sec-literals-numeric-literals)
(octal, binary).
+* Harmony [array and generator
comprehensions](http://wingolog.org/archives/2014/03/07/es6-generator-and-array-comprehensions-in-spidermonkey).
+
+## 20131106
+
+Support for:
+
+* [Arrow
functions](http://wiki.ecmascript.org/doku.php?id=harmony:arrow_function_syntax)
+* [Generators](http://wiki.ecmascript.org/doku.php?id=harmony:generators)
+* [Spread operator](http://wiki.ecmascript.org/doku.php?id=harmony:spread)
+
+## 20130510
+
+### Support for JSLint global declaration
+
+See the docstring for `js2-include-jslint-globals`.
+
+## 20130216
+
+### We don't rebind `RET` anymore
+
+Because well-behaving major modes aren't supposed to do that.
+
+So pressing it won't continue a block comment, or turn a string into a
concatenation.
+Pressing `M-j`, however, will.
+
+The options `js2-indent-on-enter-key` and `js2-enter-indents-newline` were
also removed.
+
+To bring back the previous behavior, put this in your init file:
+
+```js
+(eval-after-load 'js2-mode
+ '(define-key js2-mode-map (kbd "RET") 'js2-line-break))
+```
+
+## 20120617
+
+### Support for
[default](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/default_parameters)
and
[rest](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/rest_parameters)
parameters
+
+## 20120614
+
+### Support for [for..of
loops](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of)
+
+## Older changes
+
+### Popular indentation style
+
+```js
+[foo, bar, baz].forEach(function (v) {
+ if (validate(v))
+ process(v);
+});
+
+[a, b, c].some(function (v) {
+ return validate(v);
+});
+```
+
+### Pretty multiline variable declaration
+
+In the original mode,
+
+```js
+var foo = 10,
+bar = 20,
+baz = 30;
+```
+
+In this mode when the value of `js2-pretty-multiline-declarations` is non-nil,
+
+```js
+var foo = 10,
+ bar = 20,
+ baz = 30;
+```
+
+### Abbreviated destructuring assignments
+
+```js
+let {a, b} = {a: 10, b: 20}; // Abbreviated (Not supported in the
original mode)
+let {a: a, b: b} = {a: 10, b: 20}; // Same as above (Supported in the original
mode)
+
+(function ({responseText}) { /* */ })(xhr); // As the argument of function
+
+for (let [k, { name, age }] in Iterator(obj)) // nested
+ print(k, name, age);
+```
+
+### Expression closure in property value
+
+```js
+let worker = {
+ get age() 20,
+ get sex() "male",
+ fire: function () _fire()
+};
+```
+
+### Fix for odd indentation of "else if" with no braces
+
+In the original mode,
+
+```js
+if (foo)
+ return foo;
+else if (bar)
+return bar; // here
+```
+
+In this mode,
+
+```js
+if (foo)
+ return foo;
+else if (bar)
+ return bar; // fixed
+```
+
+### Imenu support for function nesting
+
+Supports function nesting and anonymous wrappers:
+
+```js
+(function() {
+ var foo = function() {
+ function bar() { // shown as foo.bar.<definition-1>
+ function baz() {} // foo.bar.baz
+ var qux = function() {}; // foo.bar.quux
+ }
+ };
+});
+```
+
+Examples of output:
+
+* [jQuery 1.5](https://gist.github.com/845449)
+* [Underscore.js](https://gist.github.com/824262)
+* [Backbone.js](https://gist.github.com/824260)
+
+For library-specific extension methods like `$.extend` and `dojo.declare`, see
[js2-imenu-extras](/mooz/js2-mode/blob/master/js2-imenu-extras.el).
+
+### Undeclared/external variables highlighting
+
+Original mode highlights them only on the left side of assignments:
+
+```js
+var house;
+hose = new House(); // highlights "hose"
+```
+
+Here they are highlighted in all expressions:
+
+```js
+function feed(fishes, food) {
+ for each (var fish in fshes) { // highlights "fshes"
+ food.feed(fsh); // highlights "fsh"
+ }
+ hood.discard(); // highlights "hood"
+}
+```
+
+Destructuring assignments and array comprehensions (JS 1.7) are supported:
+
+```js
+let three, [one, two] = [1, 2];
+thee = one + two; // highlights "thee"
+
+function revenue(goods) {
+ // highlights "coast"
+ return [price - coast for each ({price, cost} in goods)].reduce(add);
+}
+```
