1.7.0 - Coffeescript

releaseHeader('2014-01-28', '1.7.0', '1.6.3')

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.
