I'm happy to announce that the next version of Datatest is now
available. This update includes improved data handling features
and support for Python 3.7.

Datatest supports test driven data-wrangling, data validation, and
analysis (for both pytest and unittest style testing).

* Changed Query class:
    * Added flatten() method to serialize dictionary results.

    * Changed reduce() method to accept "initializer_factory" as
      an optional argument.
    * Changed filter() method to support predicate matching.
* Added True and False as predicates to support "truth value testing" on
  arbitrary objects (to match on truthy or falsy).
* Added ProxyGroup class for performing the same operations on groups of
  objects at the same time (a common need when testing against reference
* Changed Selector class keyword filtering to support predicate matching.
