 allowed in JavaScript, we're careful not to tag them as keywords when
 referenced as property names here, so you can still do <code>jQuery.is()</code> even

+      Official CoffeeScript variable style is now camelCase, as in JavaScript.

+      Range comprehensions now generate cleaner code, but you have to specify <tt>by -1</tt>
+      if you'd like to iterate downward. Reporting of syntax errors is greatly 
+      improved from the previous release. Running <tt>coffee</tt> with no arguments
+      now launches the REPL, with Readline support. The <tt>&amp;-</tt> bind operator
+      has been removed from CoffeeScript. The <tt>loop</tt> keyword was added,
+      which is equivalent to a <tt>while true</tt> loop. Comprehensions that contain
+      closures will now close over their variables, like the semantics of a <tt>forEach</tt>.
+      You can now use bound function in class definitions (bound to the instance).
+      For consistency, <tt>a in b</tt> is now an array presence check, and <tt>a of b</tt>
+      is an object-key check. Comments are no longer passed through to the generated

+      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 <tt>by -1</tt>
+      if you'd like to iterate downward. Reporting of syntax errors is greatly 
+      improved from the previous release. Running <tt>coffee</tt> with no arguments
+      now launches the REPL, with Readline support. The <tt>&amp;-</tt> bind operator
+      has been removed from CoffeeScript. The <tt>loop</tt> keyword was added,
+      which is equivalent to a <tt>while true</tt> loop. Comprehensions that contain
+      closures will now close over their variables, like the semantics of a <tt>forEach</tt>.
+      You can now use bound function in class definitions (bound to the instance).
+      For consistency, <tt>a in b</tt> is now an array presence check, and <tt>a of b</tt>
+      is an object-key check. Comments are no longer passed through to the generated
+      JavaScript.
