</h2>

<p>
|

<b class="header" style="margin-top: 20px;">0.9.2</b>
|
||||
Specifying the start and end of a range literal is now optional, eg. <tt>array[3..]</tt>.
|
||||
You can now say <tt>a not instanceof b</tt>.
|
||||
Fixed important bugs with nested significant and non-significant indentation (Issue #637).
|
||||
Added a <tt>--require</tt> flag that allows you to hook into the <tt>coffee</tt> command.
|
||||
Added a custom <tt>jsl.conf</tt> 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.
|
||||
</p>

<b class="header" style="margin-top: 20px;">0.9.1</b>

A version of <a href="http://wiki.ecmascript.org/doku.php?id=strawman:string_interpolation">ECMAScript Harmony's proposed string interpolation</a>

is included in CoffeeScript. Simple variables can be included by prefixing

them with a hash mark.
|
||||
Ruby-style string interpolation is included in CoffeeScript. Double-quoted
|

strings allow for interpolated values, while single-quoted strings are literal.

<b class="header" style="margin-top: 20px;">0.9.2</b>
|
||||
Specifying the start and end of a range literal is now optional, eg. <tt>array[3..]</tt>.
|
||||
You can now say <tt>a not instanceof b</tt>.
|
||||
Fixed important bugs with nested significant and non-significant indentation (Issue #637).
|
||||
Added a <tt>--require</tt> flag that allows you to hook into the <tt>coffee</tt> command.
|
||||
Added a custom <tt>jsl.conf</tt> 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.
