Released on June 24 2015.
Codename: 'Mastrolindo'.

should validate (C.D. Clark III).

validate (C.D. Clark III).
- New: 'anyof' rule accepts a list of definitions and checks that one
definition validates (C.D. Clark III).
- New: 'allof' rule validates if if all definitions validate (C.D. Clark III).

a validated document or 'None' if validation failed (Frank Sachsenheim).
- New: PyPy support (Frank Sachsenheim).

'validator.errors', and offending field indexes are used as keys for field
errors ({'a_list_of_strings': {1: 'not a string'}}) 'type' can be a list of
valid types.
- Fix: Ensure that additional `**kwargs` of a subclass persist through
validation (Frank Sachsenheim).
- Fix: improve failure message when testing against multiple types (Frank
Sachsenheim).
