CHANGES

v1.2.4, 10/21/2015 -- Added trove classifiers to setup.py so that
validator.py correctly appears as Python3 compatible on PyPI.
Added Python 3.5 to the list of tested versions.

v1.2.0, 8/10/2014 -- Added exception handling so that validations
that fail because of e.g. type mismatches report a failure
rather than blowing up.

v1.1.0, 7/03/2014 -- Added the Each validator, which applies a set
of validations to every element in a container.

v1.0.0, 4/13/2014 -- Major version release. Default validators now
inherit from Validator abstract class. Single validators are no
longer required to be wrapped in a list.

v0.8.0, 4/03/2014 -- Added Contains and Length validators. Created
'validator.ext' module for extensions, moved ArgSpec into extensions.

v0.7.0, 3/01/2014 -- Tests now support Python 3.x.  v0.6.1, 1/30/2014
-- Fixed bug causing exceptions to be thrown when optional keys
were missing.

v0.6.0, 1/28/2014 -- Implemented nested validations, also removed
the list of negated error messages out of the Not validator. All
validators are now responsible for having their own .not_message
attribute which should contain a negated version of their normal
error message. Those that don't will have a generic error message
substituted in for them.
