Changes

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.
