+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at maintainers@coffeescript.org. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

+<!---
+Thanks for filing an issue 😄! Before you submit, please read the following:
+
+Search open/closed issues before submitting since someone might have asked the same thing before!
+Our issues history stretches back to 2009, so the odds are good that your topic has come up.
+
+If you have a support request or question please use Stack Overflow:
+https://stackoverflow.com/questions/tagged/coffeescript
+
+Issues on GitHub are only related to problems of the CoffeeScript compiler itself and we cannot answer
+support questions here.
+-->
+
+Choose one: is this a bug report or feature request?
+
+<!---
+Provide a general summary of the issue in the title above.
+
+For bugs, please also preface your title with “Bug:”. For feature requests, please preface your title
+with “Proposal:”. Once your issue is reviewed, a maintainer will edit the title to refer to the part
+of the codebase most relevant to the issue (if applicable).
+
+If your request is that CoffeeScript support a new feature recently arrived to JavaScript, please note
+that we generally only add features that have reached Stage 4 in the specification (in other words,
+the syntax is finalized and the feature is approved to be part of the next ES release). You can still
+open an issue, but it will likely be tagged with “[Awaiting Stage 4]” until the relevant ES feature is
+approved for release. See https://coffeescript.org/#contributing
+
+There are also a handful of JavaScript features that CoffeeScript intentionally does not support.
+Please do not open issues regarding these. They’re listed in https://coffeescript.org/#unsupported
+-->
+
+### Input Code
+<!--- If you're describing a bug, please let us know which sample code reproduces your problem. -->
+<!--- If you have link from https://coffeescript.org/#try or a standalone repo please include that! -->
+
+```coffee
+your (code) => here
+```
+
+### Expected Behavior
+<!--- If you’re describing a bug, tell us what should happen. -->
+<!--- If you’re suggesting a change/improvement, tell us how it should work. -->
+
+### Current Behavior
+<!--- If describing a bug, tell us what happens instead of the expected behavior. -->
+<!--- If suggesting a change/improvement, explain the difference from current behavior. -->
+
+### Possible Solution
+<!--- Not obligatory, but suggest a fix/reason for the bug, -->
+<!--- or ideas how to implement the addition or change. -->
+
+### Context
+<!--- How has this issue affected you? What are you trying to accomplish? -->
+<!--- Providing context helps us come up with a solution that is most useful in the real world. -->
+
+### Environment
+<!--- For bugs, please let us know what version of CoffeeScript you’re running: `coffee -v`. -->
+<!--- If you think it might be relevant, please also let us know your version of Node. -->

+Before making a PR please make sure to read our contributing guidelines:
+https://coffeescript.org/#contributing
+
+For issue references: Add a comma-separated list of a
+[closing word](https://help.github.com/articles/closing-issues-via-commit-messages/) followed by
+the ticket number fixed by the PR. It should be underlined in the preview if done correctly.
+
+All new features require tests. All but the most trivial bug fixes should also have new or updated tests.
+
+Ensure that all new code you add to the compiler can be run in the minimum version of Node listed in
+`package.json`. New tests can require newer Node runtimes, but you may need to ensure that such tests
+only run in supported runtimes; see `Cakefile` for examples of how to filter out certain tests in
+runtimes that don’t support them.
+
+Please follow the code style of the rest of the CoffeeScript codebase. Write comments in complete
+sentences using Markdown, as the comments become the [annotated source](https://coffeescript.org/#annotated-source).
+For tests proving a bug is fixed, please mention the issue number in the test description (see examples
+in the codebase).
+
+Describe your changes below in as much detail as possible.

     <p><strong>CoffeeScript is a little language that compiles into JavaScript.</strong> Underneath that awkward Java-esque patina, JavaScript has always had a gorgeous heart. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way.</p>
 <p>The golden rule of CoffeeScript is: <em>“It’s just JavaScript”</em>. The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime. You can use any existing JavaScript library seamlessly from CoffeeScript (and vice-versa). The compiled output is readable, pretty-printed, and tends to run as fast or faster than the equivalent handwritten JavaScript.</p>
 <p>The CoffeeScript compiler goes to great lengths to generate output JavaScript that runs in every JavaScript runtime, but there are exceptions. Use <a href="#generator-functions">generator functions</a>, <a href="#generator-iteration"><code>for…from</code></a>, or <a href="#tagged-template-literals">tagged template literals</a> only if you know that your <a href="http://kangax.github.io/compat-table/es6/">target runtimes can support them</a>.

 <li>CoffeeScript now provides a <a href="#generator-iteration"><code>for…from</code></a> syntax for outputting ES2015 <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of"><code>for…of</code></a>. (Sorry they couldn’t match, but we came up with <code>for…of</code> first for something else.) This allows iterating over generators or any other iterable object. Note that using <code>for…from</code> in your code makes you responsible for ensuring that either your runtime supports <code>for…of</code> or that you transpile the output JavaScript further to a version your target runtime(s) support.</li>
 <li>Triple backticks (<code>```​</code>) allow the creation of embedded JavaScript blocks where escaping single backticks is not required, which should improve interoperability with ES2015 template literals and with Markdown.</li>
 <li>Within single-backtick embedded JavaScript, backticks can now be escaped via <code>\`​</code>.</li>

+<p>We are pleased to announce CoffeeScript 2! This new release of the CoffeeScript language and compiler aims to bring CoffeeScript into the modern JavaScript era, closing gaps in compatibility with JavaScript while preserving the clean syntax that is CoffeeScript’s hallmark. In a nutshell:</p>
+<ul>
+<li>The CoffeeScript 2 compiler now translates CoffeeScript code into modern JavaScript syntax. So a CoffeeScript <code>=&gt;</code> is now output as <code>=&gt;</code>, a CoffeeScript <code>class</code> is now output using the <code>class</code> keyword, and so on. This means you may need to <a href="../#transpilation">transpile the CoffeeScript compiler’s output</a>.</li>
+<li>CoffeeScript 2 adds support for <a href="../#async-functions">async functions</a> syntax, for the future <a href="../#destructuring">object destructuring</a> syntax, and for <a href="../#jsx">JSX</a>. Some features, such as <a href="../#modules">modules</a> (<code>import</code> and <code>export</code> statements), <a href="../#generator-iteration"><code>for…of</code></a>, and <a href="../#tagged-template-literals">tagged template literals</a> were backported into CoffeeScript versions 1.11 and 1.12.</li>
+<li>All of the above was achieved with very few <a href="../#breaking-changes">breaking changes from 1.x</a>. Most current CoffeeScript projects should be able to upgrade with little or no refactoring necessary.</li>
+</ul>
+<p>CoffeeScript 2 was developed with two primary goals: remove any incompatibilities with modern JavaScript that might prevent CoffeeScript from being used on a project; and preserve as much backward compatibility as possible. <a href="../#installation">Install now</a>: <code>npm install -g coffeescript@2</code></p>
+<h2 id="modern-javascript-output">Modern JavaScript Output</h2>
+<p>From the beginning, CoffeeScript has been described as being “just JavaScript.” And today, JavaScript is ES2015 (well, ES2017; also commonly known as ES6). CoffeeScript welcomes the changes in the JavaScript world and we’re happy to stop outputting circa-1999 syntax for modern features.</p>
+<p>Many new JavaScript features, such as <code>=&gt;</code>, were informed by CoffeeScript and are one-to-one compatible, or very nearly so. This has made outputting many of CoffeeScript’s innovations into new JS syntax straightforward: not only does <code>=&gt;</code> become <code>=&gt;</code>, but <code>{ a } = obj</code> becomes <code>{ a } = obj</code>, <code>&quot;a#{b}c&quot;</code> becomes <code>`a${b}c`</code> and so on.</p>
+<p>The following CoffeeScript features were updated in 2.0 to output using modern JavaScript syntax (or added in CoffeeScript 1.11 through 2.0, output using modern syntax):</p>
+<ul>
+<li>Modules: <code>import</code>/<code>export</code></li>
+<li>Classes: <code>class Animal</code></li>
+<li>Async functions: <code>await someFunction()</code></li>
+<li>Bound/arrow functions: <code>=&gt;</code></li>
+<li>Function default parameters: <code>(options = {}) -&gt;</code></li>
+<li>Function splat/rest parameters: <code>(items...) -&gt;</code></li>
+<li>Destructuring, for both arrays and objects: <code>[first, second] = items</code>, <code>{length} = items</code></li>
+<li>Object rest/spread properties: <code>{options..., force: yes}</code>, <code>{force, otherOptions...} = options</code></li>
+<li>Interpolated strings/template literals (JS backticked strings): <code>&quot;Hello, #{user}!&quot;</code></li>
+<li>Tagged template literals: <code>html&quot;&lt;strong&gt;coffee&lt;/strong&gt;&quot;</code></li>
+<li>JavaScript’s <code>for…of</code> is now available as CoffeeScript’s <code>for…from</code> (we already had a <code>for…of</code>): <code>for n from generatorFunction()</code></li>
+</ul>
+<p>Not all CoffeeScript features were adopted into JavaScript in 100% the same way; most notably, <a href="../#breaking-changes-default-values">default values</a> in JavaScript (and also in CoffeeScript 2) are only applied when a variable is <code>undefined</code>, not <code>undefined</code> or <code>null</code> as in CoffeeScript 1; and <a href="../#breaking-changes-classes">classes</a> have their own differences. See the <a href="../#breaking-changes">breaking changes</a> for the fine details.</p>
+<p>In our experience, most breaking changes are edge cases that should affect very few people, like JavaScript’s <a href="../#breaking-change-fat-arrow">lack of an <code>arguments</code> object inside arrow functions</a>. There seem to be two breaking changes that affect a significant number of projects:</p>
+<ul>
+<li>In CoffeeScript 2, “bare” <code>super</code> (calling <code>super</code> without arguments) is now no longer allowed, and one must use <code>super()</code> or <code>super arguments...</code> instead.</li>
+<li>References to <code>this</code>/<code>@</code> cannot occur before a call to <code>super</code>, per the JS spec.</li>
+</ul>
+<p>See the <a href="../#breaking-changes-super-extends">full details</a>. Either the CoffeeScript compiler or your transpiler will throw errors for either of these cases, so updating your code is a matter of fixing each occurrence as the compiler errors on it, until your code compiles successfully.</p>
+<h2 id="other-features">Other Features</h2>
+<p>Besides supporting new JavaScript features and outputting older CoffeeScript features in modern JS syntax, CoffeeScript 2 has added support for the following:</p>
+<ul>

+<h2 id="what-about-…">“What About …?”</h2>
+<p>A few JavaScript features have been intentionally omitted from CoffeeScript. These include <code>let</code> and <code>const</code> (and <code>var</code>), named functions and the <code>get</code> and <code>set</code> keywords. These get asked about so often that we added a section to the docs called <a href="../#unsupported">Unsupported ECMAScript Features</a>. CoffeeScript’s lack of equivalents for these features does not affect compatibility or interoperability with JavaScript modules or libraries.</p>
+<h2 id="future-compatibility">Future Compatibility</h2>
+<p>Back when CoffeeScript 1 was created, ES2015 JavaScript and transpilers like <a href="http://babeljs.io/">Babel</a>, <a href="https://buble.surge.sh/">Bublé</a> or <a href="https://github.com/google/traceur-compiler">Traceur Compiler</a> were several years away. The CoffeeScript compiler itself had to do what today’s transpilers do, converting modern features like destructuring and arrow functions into equivalent lowest-common-denominator JavaScript.</p>
+<p>But transpilers exist now, and they do their job well. With them around, there’s no need for the CoffeeScript compiler to duplicate this functionality. All the CoffeeScript compiler needs to worry about now is converting the CoffeeScript version of new syntax into the JS version of that syntax, e.g. <code>&quot;Hello, #{name}!&quot;</code> into <code>`Hello, ${name}!`</code>. This makes adding support for new JavaScript features much easier than before.</p>
+<p>Most features added by ECMA in recent years haven’t required any updates at all in CoffeeScript. New global objects, or new methods on global objects, don’t require any updates on CoffeeScript’s part to work. Some proposed future JS features <em>do</em> involve new syntax, like <a href="https://github.com/tc39/proposal-class-fields">class fields</a>. We have adopted a policy of supporting new syntax only when it reaches Stage 4 in ECMA’s process, which means that the syntax is final and will be in the next ES release. On occasion we might support a <em>feature</em> before it has reached Stage 4, but output it using equivalent non-experimental syntax instead of the newly-proposed syntax; that’s what’s happening in 2.0.0 for <a href="../#splats">object destructuring</a>, where our output uses the same polyfill that Babel uses. When the new syntax is finalized, we will update our output to use the final syntax.</p>
+<h2 id="credits">Credits</h2>
+<p>The major features of 2.0.0 would not have been possible without the following people:</p>

+# Announcing CoffeeScript 2
+
+We are pleased to announce CoffeeScript 2! This new release of the CoffeeScript language and compiler aims to bring CoffeeScript into the modern JavaScript era, closing gaps in compatibility with JavaScript while preserving the clean syntax that is CoffeeScript’s hallmark. In a nutshell:
+
+- The CoffeeScript 2 compiler now translates CoffeeScript code into modern JavaScript syntax. So a CoffeeScript `=>` is now output as `=>`, a CoffeeScript `class` is now output using the `class` keyword, and so on. This means you may need to [transpile the CoffeeScript compiler’s output](../#es2015plus-output).
+- CoffeeScript 2 adds support for [async functions](../#async-functions) syntax, for the future [object destructuring](../#destructuring) syntax, and for [JSX](../#jsx). Some features, such as [modules](../#modules) (`import` and `export` statements), [`for…of`](../#generator-iteration), and [tagged template literals](../#tagged-template-literals) were backported into CoffeeScript versions 1.11 and 1.12.
+- All of the above was achieved with very few [breaking changes from 1.x](../#breaking-changes). Most current CoffeeScript projects should be able to upgrade with little or no refactoring necessary.
+
+CoffeeScript 2 was developed with two primary goals: remove any incompatibilities with modern JavaScript that might prevent CoffeeScript from being used on a project; and preserve as much backward compatibility as possible. [Install now](../#installation): `npm install -g coffeescript@2`
+
+## Modern JavaScript Output
+
+From the beginning, CoffeeScript has been described as being “just JavaScript.” And today, JavaScript is ES2015 (well, ES2017; also commonly known as ES6). CoffeeScript welcomes the changes in the JavaScript world and we’re happy to stop outputting circa-1999 syntax for modern features.
+
+Many new JavaScript features, such as `=>`, were informed by CoffeeScript and are one-to-one compatible, or very nearly so. This has made outputting many of CoffeeScript’s innovations into new JS syntax straightforward: not only does `=>` become `=>`, but `{ a } = obj` becomes `{ a } = obj`, `"a#{b}c"` becomes `` `a${b}c` `` and so on.
+
+The following CoffeeScript features were updated in 2.0 to output using modern JavaScript syntax (or added in CoffeeScript 1.11 through 2.0, output using modern syntax):
+
+- Modules: `import`/`export`
+- Classes: `class Animal`
+- Async functions: `await someFunction()`
+- Bound/arrow functions: `=>`
+- Function default parameters: `(options = {}) ->`
+- Function splat/rest parameters: `(items...) ->`
+- Destructuring, for both arrays and objects: `[first, second] = items`, `{length} = items`
+- Object rest/spread properties: `{options..., force: yes}`, `{force, otherOptions...} = options`
+- Interpolated strings/template literals (JS backticked strings): `"Hello, #{user}!"`
+- Tagged template literals: `html"<strong>coffee</strong>"`
+- JavaScript’s `for…of` is now available as CoffeeScript’s `for…from` (we already had a `for…of`): `for n from generatorFunction()`
+
+Not all CoffeeScript features were adopted into JavaScript in 100% the same way; most notably, [default values](../#breaking-changes-default-values) in JavaScript (and also in CoffeeScript 2) are only applied when a variable is `undefined`, not `undefined` or `null` as in CoffeeScript 1; and [classes](../#breaking-changes-classes) have their own differences. See the [breaking changes](../#breaking-changes) for the fine details.
+
+In our experience, most breaking changes are edge cases that should affect very few people, like JavaScript’s [lack of an `arguments` object inside arrow functions](../#breaking-change-fat-arrow). There seem to be two breaking changes that affect a significant number of projects:
+
+- In CoffeeScript 2, “bare” `super` (calling `super` without arguments) is now no longer allowed, and one must use `super()` or `super arguments...` instead.
+- References to `this`/`@` cannot occur before a call to `super`, per the JS spec.
+
+See the [full details](../#breaking-changes-super-extends). Either the CoffeeScript compiler or your transpiler will throw errors for either of these cases, so updating your code is a matter of fixing each occurrence as the compiler errors on it, until your code compiles successfully.
+
+## Other Features
+
+Besides supporting new JavaScript features and outputting older CoffeeScript features in modern JS syntax, CoffeeScript 2 has added support for the following:
+
+- [JSX](../#jsx)
+- [Line comments](../#comments) are now output (in CoffeeScript 1 they were discarded)
+- Block comments are now allowed anywhere, enabling [static type annotations](../#type-annotations) using Flow’s comment-based syntax
+
+There are many smaller improvements as well, such as to the `coffee` command-line tool. You can read all the details in the [changelog](../#changelog) for the 2.0.0 betas.
+
+## “What About …?”
+
+A few JavaScript features have been intentionally omitted from CoffeeScript. These include `let` and `const` (and `var`), named functions and the `get` and `set` keywords. These get asked about so often that we added a section to the docs called [Unsupported ECMAScript Features](../#unsupported). CoffeeScript’s lack of equivalents for these features does not affect compatibility or interoperability with JavaScript modules or libraries.
+
+## Future Compatibility
+
+Back when CoffeeScript 1 was created, ES2015 JavaScript and transpilers like [Babel](http://babeljs.io/), [Bublé](https://buble.surge.sh/) or [Traceur Compiler](https://github.com/google/traceur-compiler) were several years away. The CoffeeScript compiler itself had to do what today’s transpilers do, converting modern features like destructuring and arrow functions into equivalent lowest-common-denominator JavaScript.
+
+But transpilers exist now, and they do their job well. With them around, there’s no need for the CoffeeScript compiler to duplicate this functionality. All the CoffeeScript compiler needs to worry about now is converting the CoffeeScript version of new syntax into the JS version of that syntax, e.g. `"Hello, #{name}!"` into `` `Hello, ${name}!` ``. This makes adding support for new JavaScript features much easier than before.
+
+Most features added by ECMA in recent years haven’t required any updates at all in CoffeeScript. New global objects, or new methods on global objects, don’t require any updates on CoffeeScript’s part to work. Some proposed future JS features _do_ involve new syntax, like [class fields](https://github.com/tc39/proposal-class-fields). We have adopted a policy of supporting new syntax only when it reaches Stage 4 in ECMA’s process, which means that the syntax is final and will be in the next ES release. On occasion we might support a _feature_ before it has reached Stage 4, but output it using equivalent non-experimental syntax instead of the newly-proposed syntax; that’s what’s happening in 2.0.0 for [object destructuring](../#splats), where our output uses the same polyfill that Babel uses. When the new syntax is finalized, we will update our output to use the final syntax.

+### Argument parsing and shebang (`#!`) lines
+
+In CoffeeScript 1.x, `--` was required after the path and filename of the script to be run, but before any arguments passed to that script. This convention is now deprecated. So instead of:
+
+```bash
+coffee [options] path/to/script.coffee -- [args]
+```
+
+Now you would just type:
+
+```bash
+coffee [options] path/to/script.coffee [args]
+```
+
+The deprecated version will still work, but it will print a warning before running the script.
+
+On non-Windows platforms, a `.coffee` file can be made executable by adding a shebang (`#!`) line at the top of the file and marking the file as executable. For example:
+
+```coffee
+#!/usr/bin/env coffee
+
+x = 2 + 2
+console.log x
+```
+
+If this were saved as `executable.coffee`, it could be made executable and run:
+
+```bash
+▶ chmod +x ./executable.coffee
+▶ ./executable.coffee
+4
+```
+
+In CoffeeScript 1.x, this used to fail when trying to pass arguments to the script. Some users on OS X worked around the problem by using `#!/usr/bin/env coffee --` as the first line of the file. That didn’t work on Linux, however, which cannot parse shebang lines with more than a single argument. While such scripts will still run on OS X, CoffeeScript will now display a warning before compiling or evaluating files that begin with a too-long shebang line. Now that CoffeeScript 2 supports passing arguments without needing `--`, we recommend simply changing the shebang lines in such scripts to just `#!/usr/bin/env coffee`.

+In CoffeeScript 1.x, `=>` compiled to a regular `function` but with references to `this`/`@` rewritten to use the outer scope’s `this`, or with the inner function bound to the outer scope via `.bind` (hence the name “bound function”). In CoffeeScript 2, `=>` compiles to [ES2015’s `=>`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), which behaves slightly differently. The largest difference is that in ES2015, `=>` functions lack an `arguments` object:

+With the addition of [JSX](#jsx), the `<` and `>` characters serve as both the “less than” and “greater than” operators and as the delimiters for XML tags, like `<div>`. For best results, in general you should always wrap the operators in spaces to distinguish them from XML tags: `i < len`, not `i<len`. The compiler tries to be forgiving when it can be sure what you intend, but always putting spaces around the “less than” and “greater than” operators will remove ambiguity.

 ## Changelog

-```
-releaseHeader('2017-05-16', '2.0.0-beta2', '2.0.0-beta1')
-```
-
-*   This release includes [all the changes from 1.12.5 to 1.12.6](#1.12.6).
-*   Bound (fat arrow) methods in classes must be declared in the class constructor, after `super()` if the class is extending a parent class. See [breaking changes for classes](#breaking-changes-classes).
-*   All unnecessary utility helper functions have been removed, including the polyfills for `indexOf` and `bind`.
-*   The `extends` keyword now only works in the context of classes; it cannot be used to extend a function prototype. See [breaking changes for `extends`](#breaking-changes-super-extends).
-*   Literate CoffeeScript is now parsed entirely based on indentation, similar to the 1.x implementation; there is no longer a dependency for parsing Markdown. See [breaking changes for Literate CoffeeScript parsing](#breaking-changes-literate-coffeescript).
-*   JavaScript reserved words used as properties are no longer wrapped in quotes.
-*   `require('coffeescript')` should now work in non-Node environments such as the builds created by Webpack or Browserify. This provides a more convenient way to include the browser compiler in builds intending to run in a browser environment.
-*   Unreachable `break` statements are no longer added after `switch` cases that `throw` exceptions.
-*   The browser compiler is now compiled using Babili and transpiled down to Babel’s `env` preset (should be safe for use in all browsers in current use, not just evergreen versions).
-*   Calling functions `@get` or `@set` no longer throws an error about required parentheses. (Bare `get` or `set`, not attached to an object or `@`, [still intentionally throws a compiler error](#unsupported-get-set).)
-*   If `$XDG_CACHE_HOME` is set, the REPL `.coffee_history` file is saved there.
-
-```
-releaseHeader('2017-05-15', '1.12.6', '1.12.5')
-```
-
-*   The `return` and `export` keywords can now accept implicit objects (defined by indentation, without needing braces).
-*   Support Unicode code point escapes (e.g. `\u{1F4A9}`).
-*   The `coffee` command now first looks to see if CoffeeScript is installed under `node_modules` in the current folder, and executes the `coffee` binary there if so; or otherwise it runs the globally installed one. This allows you to have one version of CoffeeScript installed globally and a different one installed locally for a particular project. (Likewise for the `cake` command.)
-*   Bugfixes for chained function calls not closing implicit objects or ternaries.
-*   Bugfixes for incorrect code generated by the `?` operator within a termary `if` statement.
-*   Fixed some tests, and failing tests now result in a nonzero exit code.
-
-```
-releaseHeader('2017-04-14', '2.0.0-beta1', '2.0.0-alpha1')
-```
-
-*   Initial beta release of CoffeeScript 2. No further breaking changes are anticipated.
-*   Destructured objects and arrays now output using ES2015+ syntax whenever possible.
-*   Literate CoffeeScript now has much better support for parsing Markdown, thanks to using [Markdown-It](https://github.com/markdown-it/markdown-it) to detect Markdown sections rather than just looking at indentation.
-*   Calling a function named `get` or `set` now requires parentheses, to disambiguate from the `get` or `set` keywords (which are [disallowed](#unsupported-get-set)).
-*   The compiler now requires Node 7.6+, the first version of Node to support asynchronous functions without requiring a flag.
-
-```
-releaseHeader('2017-04-10', '1.12.5', '1.12.4')
-```
-
-*   Better handling of `default`, `from`, `as` and `*` within `import` and `export` statements. You can now import or export a member named `default` and the compiler won’t interpret it as the `default` keyword.
-*   Fixed a bug where invalid octal escape sequences weren’t throwing errors in the compiler.
-
-
-```
-releaseHeader('2017-02-21', '2.0.0-alpha1', '1.12.4')

-
-*   Initial alpha release of CoffeeScript 2. The CoffeeScript compiler now outputs ES2015+ syntax whenever possible. See [breaking changes](#breaking-changes).
-*   Classes are output using ES2015 `class` and `extends` keywords.
-*   Added support for `async`/`await`.
-*   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.

-
-*   The `cake` commands have been updated, with new `watch` options for most tasks. Clone the [CoffeeScript repo](https://github.com/jashkenas/coffeescript) and run `cake` at the root of the repo to see the options.
-*   Fixed a bug where `export`ing a referenced variable was preventing the variable from being declared.
-*   Fixed a bug where the `coffee` command wasn’t working for a `.litcoffee` file.
-*   Bugfixes related to tokens and location data, for better source maps and improved compatibility with downstream tools.
-
-```
-releaseHeader('2017-01-24', '1.12.3', '1.12.2')
-```
-
-*   `@` values can now be used as indices in `for` expressions. This loosens the compilation of `for` expressions to allow the index variable to be an `@` value, e.g. `do @visit for @node, @index in nodes`. Within `@visit`, the index of the current node (`@node`) would be available as `@index`.
-*   CoffeeScript’s patched `Error.prepareStackTrace` has been restored, with some revisions that should prevent the erroneous exceptions that were making life difficult for some downstream projects. This fixes the incorrect line numbers in stack traces since 1.12.2.
-*   The `//=` operator’s output now wraps parentheses around the right operand, like the other assignment operators.
-
-```
-releaseHeader('2016-12-16', '1.12.2', '1.12.1')

-
-*   The browser compiler can once again be built unminified via `MINIFY=false cake build:browser`.
-*   The error-prone patched version of `Error.prepareStackTrace` has been removed.
-*   Command completion in the REPL (pressing tab to get suggestions) has been fixed for Node 6.9.1+.
-*   The [browser-based tests](/v<%= majorVersion %>/test.html) now include all the tests as the Node-based version.
-
-```
-releaseHeader('2016-12-07', '1.12.1', '1.12.0')
-```
-
-*   You can now import a module member named `default`, e.g. `import { default } from 'lib'`. Though like in ES2015, you cannot import an entire module and name it `default` (so `import default from 'lib'` is not allowed).
-*   Fix regression where `from` as a variable name was breaking `for` loop declarations. For the record, `from` is not a reserved word in CoffeeScript; you may use it for variable names. `from` behaves like a keyword within the context of `import` and `export` statements, and in the declaration of a `for` loop; though you should also be able to use variables named `from` in those contexts, and the compiler should be able to tell the difference.
-
-```
-releaseHeader('2016-12-04', '1.12.0', '1.11.1')
-```
-
-*   CoffeeScript now supports ES2015 [tagged template literals](#tagged-template-literals). Note that using tagged template literals in your code makes you responsible for ensuring that either your runtime supports tagged template literals or that you transpile the output JavaScript further to a version your target runtime(s) support.
-*   CoffeeScript now provides a [`for…from`](#generator-iteration) syntax for outputting ES2015 [`for…of`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...of). (Sorry they couldn’t match, but we came up with `for…of` first for something else.) This allows iterating over generators or any other iterable object. Note that using `for…from` in your code makes you responsible for ensuring that either your runtime supports `for…of` or that you transpile the output JavaScript further to a version your target runtime(s) support.
-*   Triple backticks (`` ```​``) allow the creation of embedded JavaScript blocks where escaping single backticks is not required, which should improve interoperability with ES2015 template literals and with Markdown.
-*   Within single-backtick embedded JavaScript, backticks can now be escaped via `` \`​``.
-*   The browser tests now run in the browser again, and are accessible [here](/v<%= majorVersion %>/test.html) if you would like to test your browser.
-*   CoffeeScript-only keywords in ES2015 `import`s and `export`s are now ignored.
-*   The compiler now throws an error on trying to export an anonymous class.
-*   Bugfixes related to tokens and location data, for better source maps and improved compatibility with downstream tools.
-

-releaseHeader('2016-10-02', '1.11.1', '1.11.0')

-
-*   Bugfix for shorthand object syntax after interpolated keys.
-*   Bugfix for indentation-stripping in `"""` strings.
-*   Bugfix for not being able to use the name “arguments” for a prototype property of class.
-*   Correctly compile large hexadecimal numbers literals to `2e308` (just like all other large number literals do).
-
-```
-releaseHeader('2016-09-24', '1.11.0', '1.10.0')
-```
-
-*   CoffeeScript now supports ES2015 [`import` and `export` syntax](#modules).
-*   Added the `-M, --inline-map` flag to the compiler, allowing you embed the source map directly into the output JavaScript, rather than as a separate file.
-*   A bunch of fixes for `yield`:
-
-    *   `yield return` can no longer mistakenly be used as an expression.
-    *   `yield` now mirrors `return` in that it can be used stand-alone as well as with expressions. Where you previously wrote `yield undefined`, you may now write simply `yield`. However, this means also inheriting the same syntax limitations that `return` has, so these examples no longer compile:
-        ```
-        doubles = ->
-          yield for i in [1..3]
-            i * 2
-        six = ->
-          yield
-            2 * 3
-        ```
-
-    *   The JavaScript output is a bit nicer, with unnecessary parentheses and spaces, double indentation and double semicolons around `yield` no longer present.
-*   `&&=`, `||=`, `and=` and `or=` no longer accidentally allow a space before the equals sign.
-*   Improved several error messages.
-*   Just like `undefined` compiles to `void 0`, `NaN` now compiles into `0/0` and `Infinity` into `2e308`.
-*   Bugfix for renamed destructured parameters with defaults. `({a: b = 1}) ->` no longer crashes the compiler.
-*   Improved the internal representation of a CoffeeScript program. This is only noticeable to tools that use `CoffeeScript.tokens` or `CoffeeScript.nodes`. Such tools need to update to take account for changed or added tokens and nodes.
-*   Several minor bug fixes, including:
-
-    *   The caught error in `catch` blocks is no longer declared unnecessarily, and no longer mistakenly named `undefined` for `catch`-less `try` blocks.
-    *   Unassignable parameter destructuring no longer crashes the compiler.
-    *   Source maps are now used correctly for errors thrown from .coffee.md files.
-    *   `coffee -e 'throw null'` no longer crashes.
-    *   The REPL no longer crashes when using `.exit` to exit it.
-    *   Invalid JavaScript is no longer output when lots of `for` loops are used in the same scope.
-    *   A unicode issue when using stdin with the CLI.

-*   CoffeeScript now supports ES2015-style destructuring defaults.
-*   `(offsetHeight: height) ->` no longer compiles. That syntax was accidental and partly broken. Use `({offsetHeight: height}) ->` instead. Object destructuring always requires braces.
-*   Several minor bug fixes, including:
-
-    *   A bug where the REPL would sometimes report valid code as invalid, based on what you had typed earlier.
-    *   A problem with multiple JS contexts in the jest test framework.
-    *   An error in io.js where strict mode is set on internal modules.
-    *   A variable name clash for the caught error in `catch` blocks.

-*   Fixed broken error messages in the REPL, as well as a few minor bugs with the REPL.
-*   Fixed source mappings for tokens at the beginning of lines when compiling with the `--bare` option. This has the nice side effect of generating smaller source maps.
-*   Slight formatting improvement of compiled block comments.

-*   Bugfix for `yield` around expressions containing `this`.
-*   Added a Ruby-style `-r` option to the REPL, which allows requiring a module before execution with `--eval` or `--interactive`.
-*   In `<script type="text/coffeescript">` tags, to avoid possible duplicate browser requests for .coffee files, you can now use the `data-src` attribute instead of `src`.
-*   Minor bug fixes for IE8, strict ES5 regular expressions and Browserify.

-*   Changed strategy for the generation of internal compiler variable names. Note that this means that `@example` function parameters are no longer available as naked `example` variables within the function body.
-*   Fixed REPL compatibility with latest versions of Node and Io.js.
-*   Various minor bug fixes.

-*   The `--join` option of the CLI is now deprecated.
-*   Source maps now use `.js.map` as file extension, instead of just `.map`.
-*   The CLI now exits with the exit code 1 when it fails to write a file to disk.
-*   The compiler no longer crashes on unterminated, single-quoted strings.
-*   Fixed location data for string interpolations, which made source maps out of sync.
-*   The error marker in error messages is now correctly positioned if the code is indented with tabs.
-*   Fixed a slight formatting error in CoffeeScript’s source map-patched stack traces.
-*   The `%%` operator now coerces its right operand only once.
-*   It is now possible to require CoffeeScript files from Cakefiles without having to register the compiler first.
-*   The CoffeeScript REPL is now exported and can be required using `require 'coffeescript/repl'`.

-
-*   When requiring CoffeeScript files in Node you must now explicitly register the compiler. This can be done with `require 'coffeescript/register'` or `CoffeeScript.register()`. Also for configuration such as Mocha’s, use **coffeescript/register**.
-*   Improved error messages, source maps and stack traces. Source maps now use the updated `//#` syntax.
-*   Leading `.` now closes all open calls, allowing for simpler chaining syntax.
-*   Added `**`, `//` and `%%` operators and `...` expansion in parameter lists and destructuring expressions.
-*   Multiline strings are now joined by a single space and ignore all indentation. A backslash at the end of a line can denote the amount of whitespace between lines, in both strings and heredocs. Backslashes correctly escape whitespace in block regexes.
-*   Closing brackets can now be indented and therefore no longer cause unexpected error.
-*   Several breaking compilation fixes. Non-callable literals (strings, numbers etc.) don’t compile in a call now and multiple postfix conditionals compile properly. Postfix conditionals and loops always bind object literals. Conditional assignment compiles properly in subexpressions. `super` is disallowed outside of methods and works correctly inside `for` loops.
-*   Formatting of compiled block comments has been improved.
-*   No more `-p` folders on Windows.
-*   The `options` object passed to CoffeeScript is no longer mutated.

-
-*   The CoffeeScript REPL now remembers your history between sessions. Just like a proper REPL should.
-*   You can now use `require` in Node to load `.coffee.md` Literate CoffeeScript files. In the browser, `text/literate-coffeescript` script tags.
-*   The old `coffee --lint` command has been removed. It was useful while originally working on the compiler, but has been surpassed by JSHint. You may now use `-l` to pass literate files in over **stdio**.
-*   Bugfixes for Windows path separators, `catch` without naming the error, and executable-class-bodies-with- prototypal-property-attachment.
-

Also, to provide better error messages for semantic errors thrown by the compiler — [with colors, even](http://cl.ly/NdOA).
-*   Improved support for mixed literate/vanilla-style CoffeeScript projects, and generating source maps for both at the same time.
-*   Fixes for **1.6.x** regressions with overriding inherited bound functions, and for Windows file path management.
-*   The `coffee` command can now correctly `fork()` both `.coffee` and `.js` files. (Requires Node.js 0.9+)

-
-*   First release of [source maps](#source-maps). Pass the `--map` flag to the compiler, and off you go. Direct all your thanks over to [Jason Walton](https://github.com/jwalton).
-*   Fixed a 1.5.0 regression with multiple implicit calls against an indented implicit object. Combinations of implicit function calls and implicit objects should generally be parsed better now — but it still isn’t good _style_ to nest them too heavily.
-*   `.coffee.md` is now also supported as a Literate CoffeeScript file extension, for existing tooling. `.litcoffee` remains the canonical one.
-*   Several minor fixes surrounding member properties, bound methods and `super` in class declarations.
-

-
-*   First release of [Literate CoffeeScript](#literate).
-*   The CoffeeScript REPL is now based on the Node.js REPL, and should work better and more familiarly.
-*   Returning explicit values from constructors is now forbidden. If you want to return an arbitrary value, use a function, not a constructor.
-*   You can now loop over an array backwards, without having to manually deal with the indexes: `for item in list by -1`
-*   Source locations are now preserved in the CoffeeScript AST, although source maps are not yet being emitted.
-
-```
-releaseHeader('2012-10-23', '1.4.0', '1.3.3')

-
-*   The CoffeeScript compiler now strips Microsoft’s UTF-8 BOM if it exists, allowing you to compile BOM-borked source files.
-*   Fix Node/compiler deprecation warnings by removing `registerExtension`, and moving from `path.exists` to `fs.exists`.
-*   Small tweaks to splat compilation, backticks, slicing, and the error for duplicate keys in object literals.
-
-```
-releaseHeader('2012-05-15', '1.3.3', '1.3.1')

-
-*   Due to the new semantics of JavaScript’s strict mode, CoffeeScript no longer guarantees that constructor functions have names in all runtimes. See [#2052](https://github.com/jashkenas/coffeescript/issues/2052) for discussion.
-*   Inside of a nested function inside of an instance method, it’s now possible to call `super` more reliably (walks recursively up).
-*   Named loop variables no longer have different scoping heuristics than other local variables. (Reverts #643)
-*   Fix for splats nested within the LHS of destructuring assignment.
-*   Corrections to our compile time strict mode forbidding of octal literals.
-
-```
-releaseHeader('2012-04-10', '1.3.1', '1.2.0')
-```
-
-*   CoffeeScript now enforces all of JavaScript’s **Strict Mode** early syntax errors at compile time. This includes old-style octal literals, duplicate property names in object literals, duplicate parameters in a function definition, deleting naked variables, setting the value of `eval` or `arguments`, and more. See a full discussion at [#1547](https://github.com/jashkenas/coffeescript/issues/1547).
-*   The REPL now has a handy new multi-line mode for entering large blocks of code. It’s useful when copy-and-pasting examples into the REPL. Enter multi-line mode with `Ctrl-V`. You may also now pipe input directly into the REPL.
-*   CoffeeScript now prints a `Generated by CoffeeScript VERSION` header at the top of each compiled file.
-*   Conditional assignment of previously undefined variables `a or= b` is now considered a syntax error.
-*   A tweak to the semantics of `do`, which can now be used to more easily simulate a namespace: `do (x = 1, y = 2) -> …`
-*   Loop indices are now mutable within a loop iteration, and immutable between them.
-*   Both endpoints of a slice are now allowed to be omitted for consistency, effectively creating a shallow copy of the list.
-*   Additional tweaks and improvements to `coffee --watch` under Node’s “new” file watching API. Watch will now beep by default if you introduce a syntax error into a watched script. We also now ignore hidden directories by default when watching recursively.
-
-```
-releaseHeader('2011-12-18', '1.2.0', '1.1.3')

-
-*   Multiple improvements to `coffee --watch` and `--join`. You may now use both together, as well as add and remove files and directories within a `--watch`’d folder.
-*   The `throw` statement can now be used as part of an expression.
-*   Block comments at the top of the file will now appear outside of the safety closure wrapper.
-*   Fixed a number of minor 1.1.3 regressions having to do with trailing operators and unfinished lines, and a more major 1.1.3 regression that caused bound functions _within_ bound class functions to have the incorrect `this`.
-
-```
-releaseHeader('2011-11-08', '1.1.3', '1.1.2')
-```
-
-*   Ahh, whitespace. CoffeeScript’s compiled JS now tries to space things out and keep it readable, as you can see in the examples on this page.
-*   You can now call `super` in class level methods in class bodies, and bound class methods now preserve their correct context.
-*   JavaScript has always supported octal numbers `010 is 8`, and hexadecimal numbers `0xf is 15`, but CoffeeScript now also supports binary numbers: `0b10 is 2`.
-*   The CoffeeScript module has been nested under a subdirectory to make it easier to `require` individual components separately, without having to use **npm**. For example, after adding the CoffeeScript folder to your path: `require('coffeescript/lexer')`
-*   There’s a new “link” feature in Try CoffeeScript on this webpage. Use it to get a shareable permalink for your example script.
-*   The `coffee --watch` feature now only works on Node.js 0.6.0 and higher, but now also works properly on Windows.
-*   Lots of small bug fixes from **[@michaelficarra](https://github.com/michaelficarra)**, **[@geraldalewis](https://github.com/geraldalewis)**, **[@satyr](https://github.com/satyr)**, and **[@trevorburnham](https://github.com/trevorburnham)**.

-releaseHeader('2011-05-01', '1.1.0', '1.0.1')
-```
-
-When running via the `coffee` executable, `process.argv` and friends now report `coffee` instead of `node`. Better compatibility with **Node.js 0.4.x** module lookup changes. The output in the REPL is now colorized, like Node’s is. Giving your concatenated CoffeeScripts a name when using `--join` is now mandatory. Fix for lexing compound division `/=` as a regex accidentally. All `text/coffeescript` tags should now execute in the order they’re included. Fixed an issue with extended subclasses using external constructor functions. Fixed an edge-case infinite loop in `addImplicitParentheses`. Fixed exponential slowdown with long chains of function calls. Globals no longer leak into the CoffeeScript REPL. Splatted parameters are declared local to the function.
-
-```
-releaseHeader('2011-01-31', '1.0.1', '1.0.0')

-
-Fixed a lexer bug with Unicode identifiers. Updated REPL for compatibility with Node.js 0.3.7\. Fixed requiring relative paths in the REPL. Trailing `return` and `return undefined` are now optimized away. Stopped requiring the core Node.js `util` module for back-compatibility with Node.js 0.2.5\. Fixed a case where a conditional `return` would cause fallthrough in a `switch` statement. Optimized empty objects in destructuring assignment.
-
-```
-releaseHeader('2010-12-24', '1.0.0', '0.9.6')
-```
-
-CoffeeScript loops no longer try to preserve block scope when functions are being generated within the loop body. Instead, you can use the `do` keyword to create a convenient closure wrapper. Added a `--nodejs` flag for passing through options directly to the `node` executable. Better behavior around the use of pure statements within expressions. Fixed inclusive slicing through `-1`, for all browsers, and splicing with arbitrary expressions as endpoints.
-
-```
-releaseHeader('2010-12-06', '0.9.6', '0.9.5')
-```
-
-The REPL now properly formats stacktraces, and stays alive through asynchronous exceptions. Using `--watch` now prints timestamps as files are compiled. Fixed some accidentally-leaking variables within plucked closure-loops. Constructors now maintain their declaration location within a class body. Dynamic object keys were removed. Nested classes are now supported. Fixes execution context for naked splatted functions. Bugfix for inversion of chained comparisons. Chained class instantiation now works properly with splats.
-
-```
-releaseHeader('2010-11-21', '0.9.5', '0.9.4')
-```
-
-0.9.5 should be considered the first release candidate for CoffeeScript 1.0. There have been a large number of internal changes since the previous release, many contributed from **satyr**’s [Coco](https://github.com/satyr/coco) dialect of CoffeeScript. Heregexes (extended regexes) were added. Functions can now have default arguments. Class bodies are now executable code. Improved syntax errors for invalid CoffeeScript. `undefined` now works like `null`, and cannot be assigned a new value. There was a precedence change with respect to single-line comprehensions: `result = i for i in list`
-used to parse as `result = (i for i in list)` by default … it now parses as
-`(result = i) for i in list`.
-
-```
-releaseHeader('2010-09-21', '0.9.4', '0.9.3')
-```
-
-CoffeeScript now uses appropriately-named temporary variables, and recycles their references after use. Added `require.extensions` support for **Node.js 0.3**. Loading CoffeeScript in the browser now adds just a single `CoffeeScript` object to global scope. Fixes for implicit object and block comment edge cases.
-
-```
-releaseHeader('2010-09-16', '0.9.3', '0.9.2')
-```
-
-CoffeeScript `switch` statements now compile into JS `switch` statements — they previously compiled into `if/else` chains for JavaScript 1.3 compatibility. Soaking a function invocation is now supported. Users of the RubyMine editor should now be able to use `--watch` mode.
-
-```
-releaseHeader('2010-08-23', '0.9.2', '0.9.1')
-```
-
-Specifying the start and end of a range literal is now optional, eg. `array[3..]`. You can now say `a not instanceof b`. Fixed important bugs with nested significant and non-significant indentation (Issue #637). Added a `--require` flag that allows you to hook into the `coffee` command. Added a custom `jsl.conf` file for our preferred JavaScriptLint setup. Sped up Jison grammar compilation time by flattening rules for operations. Block comments can now be used with JavaScript-minifier-friendly syntax. Added JavaScript’s compound assignment bitwise operators. Bugfixes to implicit object literals with leading number and string keys, as the subject of implicit calls, and as part of compound assignment.
-
-```
-releaseHeader('2010-08-11', '0.9.1', '0.9.0')
-```
-
-Bugfix release for **0.9.1**. Greatly improves the handling of mixed implicit objects, implicit function calls, and implicit indentation. String and regex interpolation is now strictly `#{ … }` (Ruby style). The compiler now takes a `--require` flag, which specifies scripts to run before compilation.
-
-```
-releaseHeader('2010-08-04', '0.9.0', '0.7.2')
-```
-
-The CoffeeScript **0.9** series is considered to be a release candidate for **1.0**; let’s give her a shakedown cruise. **0.9.0** introduces a massive backwards-incompatible change: Assignment now uses `=`, and object literals use `:`, as in JavaScript. This allows us to have implicit object literals, and YAML-style object definitions. Half assignments are removed, in favor of `+=`, `or=`, and friends. Interpolation now uses a hash mark `#` instead of the dollar sign `$` — because dollar signs may be part of a valid JS identifier. Downwards range comprehensions are now safe again, and are optimized to straight for loops when created with integer endpoints. A fast, unguarded form of object comprehension was added: `for all key, value of object`. Mentioning the `super` keyword with no arguments now forwards all arguments passed to the function, as in Ruby. If you extend class `B` from parent class `A`, if `A` has an `extended` method defined, it will be called, passing in `B` — this enables static inheritance, among other things. Cleaner output for functions bound with the fat arrow. `@variables` can now be used in parameter lists, with the parameter being automatically set as a property on the object — useful in constructors and setter functions. Constructor functions can now take splats.
-
-```
-releaseHeader('2010-07-12', '0.7.2', '0.7.1')
-```
-
-Quick bugfix (right after 0.7.1) for a problem that prevented `coffee` command-line options from being parsed in some circumstances.
-
-```
-releaseHeader('2010-07-11', '0.7.1', '0.7.0')
-```
-
-Block-style comments are now passed through and printed as JavaScript block comments – making them useful for licenses and copyright headers. Better support for running coffee scripts standalone via hashbangs. Improved syntax errors for tokens that are not in the grammar.
-
-```
-releaseHeader('2010-06-28', '0.7.0', '0.6.2')
-```
-
-Official CoffeeScript variable style is now camelCase, as in JavaScript. Reserved words are now allowed as object keys, and will be quoted for you. Range comprehensions now generate cleaner code, but you have to specify `by -1` if you’d like to iterate downward. Reporting of syntax errors is greatly improved from the previous release. Running `coffee` with no arguments now launches the REPL, with Readline support. The `<-` bind operator has been removed from CoffeeScript. The `loop` keyword was added, which is equivalent to a `while true` loop. Comprehensions that contain closures will now close over their variables, like the semantics of a `forEach`. You can now use bound function in class definitions (bound to the instance). For consistency, `a in b` is now an array presence check, and `a of b` is an object-key check. Comments are no longer passed through to the generated JavaScript.
-
-```
-releaseHeader('2010-05-15', '0.6.2', '0.6.1')
-```
-
-The `coffee` command will now preserve directory structure when compiling a directory full of scripts. Fixed two omissions that were preventing the CoffeeScript compiler from running live within Internet Explorer. There’s now a syntax for block comments, similar in spirit to CoffeeScript’s heredocs. ECMA Harmony DRY-style pattern matching is now supported, where the name of the property is the same as the name of the value: `{name, length}: func`. Pattern matching is now allowed within comprehension variables. `unless` is now allowed in block form. `until` loops were added, as the inverse of `while` loops. `switch` statements are now allowed without switch object clauses. Compatible with Node.js **v0.1.95**.
-
-```
-releaseHeader('2010-04-12', '0.6.1', '0.6.0')

-
-Upgraded CoffeeScript for compatibility with the new Node.js **v0.1.90** series.

-
-```
-releaseHeader('2010-03-23', '0.5.6', '0.5.5')
-```
-
-Interpolation can now be used within regular expressions and heredocs, as well as strings. Added the `<-` bind operator. Allowing assignment to half-expressions instead of special `||=`-style operators. The arguments object is no longer automatically converted into an array. After requiring `coffeescript`, Node.js can now directly load `.coffee` files, thanks to **registerExtension**. Multiple splats can now be used in function calls, arrays, and pattern matching.
-
-```
-releaseHeader('2010-03-08', '0.5.5', '0.5.4')
-```
-
-String interpolation, contributed by [Stan Angeloff](https://github.com/StanAngeloff). Since `--run` has been the default since **0.5.3**, updating `--stdio` and `--eval` to run by default, pass `--compile` as well if you’d like to print the result.
-
-```
-releaseHeader('2010-03-03', '0.5.4', '0.5.3')

-
-```
-releaseHeader('2010-02-27', '0.5.3', '0.5.2')

-
-CoffeeScript now has a syntax for defining classes. Many of the core components (Nodes, Lexer, Rewriter, Scope, Optparse) are using them. Cakefiles can use `optparse.coffee` to define options for tasks. `--run` is now the default flag for the `coffee` command, use `--compile` to save JavaScripts. Bugfix for an ambiguity between RegExp literals and chained divisions.
-
-```
-releaseHeader('2010-02-25', '0.5.2', '0.5.1')
-```
-
-Added a compressed version of the compiler for inclusion in web pages as
-`/v<%= majorVersion %>/browser-compiler/coffeescript.js`. It’ll automatically run any script tags with type `text/coffeescript` for you. Added a `--stdio` option to the `coffee` command, for piped-in compiles.
-
-```
-releaseHeader('2010-02-24', '0.5.1', '0.5.0')

-

+Added a compressed version of the compiler for inclusion in web pages as
+`/v<%= majorVersion %>/browser-compiler-legacy/coffeescript.js`. It’ll automatically run any script tags with type `text/coffeescript` for you. Added a `--stdio` option to the `coffee` command, for piped-in compiles.

+CoffeeScript now has a syntax for defining classes. Many of the core components (Nodes, Lexer, Rewriter, Scope, Optparse) are using them. Cakefiles can use `optparse.coffee` to define options for tasks. `--run` is now the default flag for the `coffee` command, use `--compile` to save JavaScripts. Bugfix for an ambiguity between RegExp literals and chained divisions.
