------------------
* Simpler ``NagiosLogger`` interface. (backwards incompatible)
* Feature: ``Testcase.assertSoftCalledWith`` method for mock partial call
assertions.
* FIX: ``NagiosLogger`` was not restoring stdout.
* FIX: ``NagiosLogger`` choked when output contained empty lines.
* Feature: ``namedtuple_with_defaults`` uses a ``lambda`` instead of a
classmethod for mutable defaults. (backwards incompatible)
