+variables are new and need to be declared with <code>var</code>, and which are shared
+with external scopes.</p>

+## Breaking Changes From CoffeeScript 1.x to 2
+
+CoffeeScript 2 aims to output as much idiomatic ES2015+ syntax as possible with as few breaking changes from CoffeeScript 1.x as possible. Some breaking changes, unfortunately, were unavoidable.
+
+### Function parameter default values
+
+Per the [ES2015 spec regarding default parameters](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Default_parameters), default values are only applied when a parameter value is missing or `undefined`. In CoffeeScript 1.x, the default value would be applied in those cases but also if the parameter value was `null`.
+
+```
+codeFor('breaking_change_function_parameter_default_values', 'f(null)')
+```
+
+### Bound generator functions
+
+Bound generator functions, a.k.a. generator arrow functions, [aren’t allowed in ECMAScript](http://stackoverflow.com/questions/27661306/can-i-use-es6s-arrow-function-syntax-with-generators-arrow-notation). You can write `function*` or `=>`, but not both. Therefore, CoffeeScript code like this:
+
+> ```coffee
+f = => yield this  # Throws a compiler error
+```
+
+Needs to be rewritten the old-fashioned way:
+
+```
+codeFor('breaking_change_bound_generator_function')
+```
+
+### Classes are compiled to ES2015 classes
+
+ES2015 classes and their methods have some restrictions beyond those on regular functions.
+
+Class constructors can’t be invoked without `new`:
+
+> ```coffee
+(class)()  # Throws a TypeError at runtime
+```
+
+Derived (extended) class `constructor`s cannot use `this` before calling `super`:
+
+> ```coffee
+class B extends A
+  constructor: -> this  # Throws a compiler error
+```
+
+Class methods can’t be used with `new` (uncommon):
+
+> ```coffee
+class Namespace
+  @Klass = ->
+new Namespace.Klass  # Throws a TypeError at runtime
+```
+
+### Bare `super`
+
+Due to a syntax clash with `super` with accessors, bare `super` no longer compiles to a super call forwarding all arguments.
+
+> ```coffee
+class B extends A
+  foo: -> super    # Throws a compiler error
+```
+
+Arguments can be forwarded explicitly using splats:
+
+```
+codeFor('breaking_change_super_with_arguments')
+```
+
+Or if you know that the parent function doesn’t require arguments, just call `super()`:
+
+```
+codeFor('breaking_change_super_without_arguments')
+```
+
+### `super` in non-class methods
+
+In CoffeeScript 1.x it is possible to use `super` in more than just class methods, such as in manually prototype-assigned functions:
+
+> ```coffee
+A = ->
+B = ->
+B extends A
+B.prototype.foo = -> super arguments...  # Throws a compiler error
+```
+
+Due to the switch to ES2015 `super`, this is no longer supported. The above case could be refactored to:
+
+```
+codeFor('breaking_change_super_in_non-class_methods_refactor_with_apply')
+```
+
+or
+
+```
+codeFor('breaking_change_super_in_non-class_methods_refactor_with_class')
+```
+
+### Dynamic class keys exclude executable class scope
+
+Due to the hoisting required to compile to ES2015 classes, dynamic keys in class methods can’t use values from the executable class body unless the methods are assigned in prototype style.
+
+> ```coffee
+class A
+  name = 'method'
+  "#{name}": ->   # This method will be named 'undefined'
+  @::[name] = ->  # This will work; assigns to `A.prototype.method`
+```

+*   Bound (arrow) functions now output as `=>` functions.
+*   Function parameters with default values now use ES2015 default values syntax.
+*   Splat function parameters now use ES2015 spread syntax.
+*   Computed properties now use ES2015 syntax.
+*   Interpolated strings (template literals) now use ES2015 backtick syntax.
+*   Improved support for recognizing Markdown in Literate CoffeeScript files.
+*   Mixing tabs and spaces in indentation is now disallowed.
+*   Browser compiler is now minified using the Google Closure Compiler (JavaScript version).
+*   Node 7+ required for CoffeeScript 2.

-## Classes, Inheritance, and Super
+## Classes
 
-JavaScript’s prototypal inheritance has always been a bit of a brain-bender, with a whole family tree of libraries that provide a cleaner syntax for classical inheritance on top of JavaScript’s prototypes: [Base2](http://code.google.com/p/base2/), [Prototype.js](http://prototypejs.org/), [JS.Class](http://jsclass.jcoglan.com/), etc. The libraries provide syntactic sugar, but the built-in inheritance would be completely usable if it weren’t for a couple of small exceptions: it’s awkward to call **super** (the prototype object’s implementation of the current function), and it’s awkward to correctly set the prototype chain.
-
-Instead of repetitively attaching functions to a prototype, CoffeeScript provides a basic `class` structure that allows you to name your class, set the superclass, assign prototypal properties, and define the constructor, in a single assignable expression.
-
-Constructor functions are named, to better support helpful stack traces. In the first class in the example below, `this.constructor.name is "Animal"`.
+CoffeeScript 1 provided the `class` and `extends` keywords as syntactic sugar for working with prototypal functions. With ES2015, JavaScript has adopted those keywords; so CoffeeScript 2 compiles its `class` and `extends` keywords to ES2015 classes.
 
 ```
 codeFor('classes', true)
 ```
 
-If structuring your prototypes classically isn’t your cup of tea, CoffeeScript provides a couple of lower-level conveniences. The `extends` operator helps with proper prototype setup, and can be used to create an inheritance chain between any pair of constructor functions; `::` gives you quick access to an object’s prototype; and `super()` is converted into a call against the immediate ancestor’s method of the same name.
+Static methods can be defined using `@` before the method name:
 
 ```
-codeFor('prototypes', '"one_two".dasherize()')
+codeFor('static', 'Teenager.say("Are we there yet?")')
 ```
 
-Finally, class definitions are blocks of executable code, which make for interesting metaprogramming possibilities. Because in the context of a class definition, `this` is the class object itself (the constructor function), you can assign static properties by using
-`@property: value`, and call functions defined in parent classes: `@attr 'title', type: 'text'`

+## CoffeeScript 2

+CoffeeScript 2 generates JavaScript that uses the latest ES2015+ features. It is your responsibility to ensure that your target JavaScript runtime(s) support all these features, or that you pass the output through another transpiler like [Babel](http://babeljs.io/), [Rollup](https://github.com/rollup/rollup) or [Traceur Compiler](https://github.com/google/traceur-compiler). In general, [CoffeeScript 2’s output is fully supported by Node.js 7+](http://node.green/), although async functions require the `--harmony` or `--harmony-async-await` flags; and ES2015 modules require an additional transpiler. Output JavaScript intended for browsers generally requires additional transpilation.
+
+If you’re looking for a single tool that takes CoffeeScript input and generates JavaScript output that runs in any JavaScript runtime, assuming you opt out of certain newer features, stick to the [CoffeeScript 1.x branch](v1/). CoffeeScript 2 [breaks compatibility](#breaking-changes) with certain CoffeeScript 1.x features in order to conform with the ES2015+ specifications, and generate more idiomatic output (a CoffeeScript `=>` becomes an ES `=>`; a CoffeeScript `class` becomes an ES `class`; and so on).
