Changes

0.8.1

• Fixed List and Set restricting mappings from their valid input.

• Fixed cloning and representing of Const validator constructed with False or None a value.

• Fixed nullable check of Type validator constructed with object as a type.

0.8

• Dropped Python 3.5 support.

• Added Python 3.10, 3.11 support.

• Fixed handling UNIX-timestamps by Date and Datetime validators.

• Added ability to specify default time which is used to implicitly convert date to datetime within Datetime validator.

• Fixed handling bool values by Int and Float validators.

• Changed behavior of Str validator, it now strips leading & trailing whitespace by default. Use dontstrip=True parameter to disable the stripping.

• Added ability to normalize spaces by Str validator, i.e. replace space sequences by single space character. Use normspace=True parameter to enable the normalization.

• Added coerce parameter to Str validator, which can be useful to sanitize data from sources with automatic type inferring, where string data might be incorrectly interpreted as another type.

• Unified behavior of Python and Cython versions of Int validator. Both versions support unlimited integer numbers now.

• Added new Set validator.

• Added new Decimal validator.

• Renamed FloatValueError to NumberError, so it is now used for both Float and Decimal validators.

• Added new CoerceError which is raised instead of InvalidTypeError when type coercion fails.

0.7

• Dropped Python 2.7 support.

• Fixed relmin/relmax checks for Date validator with timezone.

• Fixed constructing Cython version of Type validator with type created from metaclass.

0.6.1

0.6

• Added Python 3.8 into test matrix.

• Made validators immutable.

• Added contracts checks on validator initialization.

• Added new simplified syntax for cloning validators.

• Got rid of global state within LazyRef validator. It now acts like a pure function.

• Fixed raising of ambiguous MinLengthError on List and Dict validation.

0.5.1

• Fixed type declarations. Again. One does not simply make mypy happy.

0.5

• Removed confusing nullable check from Any validator.

• Fixed type declarations.

0.4

• Fixed library objects pickling.

0.3

• Fixed handling of default values and length validation within Dict validator.

0.2
