CoffeeScript 1.7.0 发布，此版本更新内容如下：
When requiring CoffeeScript files in Node you must now explicitly register the compiler. This can be done with require 'coffee-script/register' or CoffeeScript.register(). Also for configuration such as Mocha's, use coffee-script/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 paramater 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.
CoffeeScript这一门编程语言构建在JavaScript之上，其被编译成高效的JavaScript，这样你就可以在web浏览器上运行它，或是通过诸如用于服务器端应用的Node.js一类的技术来使用它。编译过程通常都很简单，产生出来的JavaScript与许多的最佳做法都保持了一致。
