-All Should-DSL releases **before 2.0** uses a deprecated style, although we still support this old style, it will be dropped soon and we discourage you to use that style. Old style usage like::
-
-    >>> 3 |should_not.equal_to| 2.99
-
-should be written as::
-
-    >>> 3 |should_not| equal_to(2.99)
-
-
-This new syntax for writing expectations has been changed because the requirement to have a single "right value" had been a limition to write new matchers and add other enhancements to Should-DSL and you should update the code that uses old style, because we plan to remove them soon.
