1.6.0

New keywords:

• Add support for keyword example. It does nothing and have no validation done on it.
• Add support for keyword version. It does nothing and have no validation done on it.
• Add support for keyword date and added support keyword format. This can be used to validate many different types of datetime objects.
• Add support for keyword length. It is very similar to range but works primarily string types.
• Add support for keyword assert. It works by running the python code assert and check if any exception is raised.
  This feature is considered dangerouns becuase there is only simple logic to prevent escaping out from validation.

Bug fixes:

• Fixed a bug where regexes marked as 'required' in a map were matched as strings, rather than regexes.
• Fixed a bug where the type validation did not work when schema specefied a sequence of map objects. It now outputs a proper ...is not a dict... error instead.
• Fixed a bug in unique validation when a key that it tried to lookup in the data would not exists.
  Now it just ignores that it did not find any value becuase a missing value do not impact validation.
• Fixed a bug with keyword ident when the rule value was verified to be a boolean. It now only accepts boolean values as expected.
• Fixed a bug where if allowempty was specefied in a mapping type inside a sequence type then it would not properly validate.
• Fixed a bug where loaded extensions would not allways work in complex & nested objects.
• Fixed a major bug in very nested seq schemas where if the schema expected another seq but the value was something else it would not raise it as a validation error.
  This has now been fixed and now raises the proper error.
• Fixed a bug where include directive would not work in all cases when used inside a key in a mapping block.

New features:

• It is now possible to specify a default rule when using a mapping.
  The rule will be used whenever no other key could be found.
  This is a port of a missing feature from original kwalify implementation.
• Added new helper method keywords to Rule class that can output all active keywords for any Rule object.
  This helps when debugging code to be able to easily dump what all active keywords for any Rule object.
• Added new cli flag --strict-rule-validation that will validate that all used keywords in all Rule objects only uses the rules that is supported by each defined type.
  If you only use a Core object then set strict_rule_validation=True when creating the Core object instance.
  This feature is opt-in in this releaes but will be mandatory in releases >= 1.7.0.
• Added new cli flag --fix-ruby-style-regex that will trim slashes from ruby style regex/patterns.
  When using this flag the first and last / will be trimmed of the pattern before running validation.
  If you only use a Core object then set fix_ruby_style_regex=True when creating the Core object instance.
  Default behaviour will still be that you should use python style regex values but this flag can help in some cases when you can't change the schema.
• Added new cli flag --allow-assertions that will enable the otherwise blocked keyword assert.
  This flag was introduced so that pykwalify would not assert assertions without user controll.
  Default behaviour will be to raise a CoreError is assertion is used but not allowed explicitly.
  If you only use a Core object then set allow_assertions=True when creating the Core object instance.

Changed behaviour:

• Removed the force of UTF-8 encoding when importing pykwalify package. It caused issues with jypiter notebooks on python 2.7.x
  Added documentation in Readme regarding the suggested solution to use PYTHONIOENCODING=UTF-8 if the default solution do not work.
• Validation do no longer continue to process things like pattern, regex, timestamp, range and other additional checks
  if the type check fails. This can cause problems where previous errors will now initially be silenced when the typecheck for
  that value fails, but reappear again when the type check is fixed. (sbrunner)
• Catches TypeError when doing regex validation. That happens when the value is not a parsable string type.
• Checking that the value is a valid dict object is now done even if the mapping keyword is not specefied in the schema.
  This makes that check more eager and errors can apear that previously was not there.
• Changed the sane default type if that key is not defined to be str. Before this, type had to be defined every time and the default type did not work as expected.
  This is a major change and can cause validation to either fail or to stop failing depending on the case.
• Changed validation for if a value is required and a value in a list for example is None. It now adds a normal validation errors instead of raising a CoreError.
• Value for keyword desc now MUST be a string or a RuleError will be raised.
• Value for keyword example now MUST be a string or a RuleError will be raised.
• Value for keyword name now MUST be a string or a RuleError will be raised.

General changes:

• Ported alot of testcases directly from Kwalify test data (test-validator.yaml -> 30f.yaml & 43s.yaml) so that this lib can have greater confidence that rules is implemented in the same way as Kwalify.
• Refactored test_core_files method to now accept test files with multiple of documents. The method now tries to read all documents from each test file and run each document seperatly.
  It now alos reports more detailed about what file and document that fails the test to make it easier to track down problems.
• Major refactoring of test files to now be grouped based on what they are testing instead of a increased counter that do not represent anything.
  It will be easier to find out what keywords lack tests and what keywords that have enough tests.
