@@ -36,7 +36,8 @@ same results as the original ``jsmin.c``. It differs in the following ways:
 - Newline characters are not allowed inside string and regex literals, except
   for line continuations in string literals (ECMA-5).
 - "return /regex/" is recognized correctly.
-- "+ ++" and "- --" sequences are not collapsed to '+++' or '---'
+- "+ +" and "- -" sequences are not collapsed to '++' or '--'
+- Newlines before ! operators are removed more sensibly
 - rJSmin does not handle streams, but only complete strings. (However, the
   module provides a "streamy" interface).
