Released 2020-11-23

-   Drop support for Python < 3.6. :pr:`554`
-   :class:`~fields.StringField` sets ``data`` to ``None`` when form
    data is empty and an initial value was not provided. Although it
    previously set an empty string, ``None`` is consistent with the
    behavior of other fields. :pr:`355`
-   Specified version of Babel required for setup to avoid errors.
    :pr:`430`
-   Replaced use of ``getattr``/``setattr`` with regular variable
    access. :issue:`482`
-   :class:`ValueError` raised by a validator are handled like regular
    exceptions. Validators need to raise
    :class:`~validators.ValidationError` or
    :class:`~validators.StopValidation` to make a validation fail.
    :issue:`445`
-   :class:`~fields.SelectField`, :class:`~fields.SelectMultipleField` and

-   Implemented :class:`~wtforms.fields.core.MonthField`. :pr:`530` :pr:`593`
-   Filters can be inline. :meth:`form.BaseForm.process` takes a
    *extra_filters* parameter. :issue:`128` :pr:`592`
-   Fields can be passed the ``name`` argument to use a HTML name
    different than their Python name. :issue:`205`, :pr:`601`
-   Render attribute names like ``for_`` and ``class_`` are normalized
    consistently so later values override those specified earlier.
    :issue:`449`, :pr:`596`
-   Flags can take non-boolean values. :issue:`406` :pr:`467`
-   Widgets are HTML5 by default. :issue:`594` :pr:`614`
