- Added type hinting (for now, 3.5-compatible) - Split `db` namespace into `db` module and `model` namespace - Changed elastic search to be created lazily for each operation - Changed to class based approach in entity serialization to allow stronger typing - Removed `required` argument from `context.get_*` family of functions; now it's implied if `default` argument is omitted - Changed `unalias_dict` implementation to use less magic inputs
