MarkupSafe functions. Their use shows a ``DeprecationWarning``.
:issue:`581`, :pr:`583`

Released 2020-04-21

- Drop support for Python 2.6, 3.3, and 3.4.

- :class:`~validators.Length` gives a more helpful error message when
``min`` and ``max`` are the same value. :pr:`266`
- :class:`~fields.SelectField` no longer coerces ``None`` to
``"None"`` allowing use of ``"None"`` as an option. :issue:`289`,
:pr:`288`
- The :class:`~widgets.TextArea` widget prepends a ``\r\n`` newline
when rendering to account for browsers stripping an initial line for
display. This does not affect the value. :issue:`238`, :pr:`395`
- HTML5 :class:`~fields.html5.IntegerField` and
:class:`~fields.html5.RangeInput` don't render the ``step="1"``
attribute by default. :pr:`343`
- ``aria_`` args are rendered the same way as ``data_`` args, by
converting underscores to hyphens. ``aria_describedby="name-help"``
becomes ``aria-describedby="name-help"``. :issue:`239`, :pr:`389`
- Added a ``check_validators`` method to :class:`~fields.Field` which
checks if the given validators are both callable, and not classes.

- HTML is escaped using MarkupSafe instead of the previous internal
implementation. :func:`~widgets.core.escape_html` is removed,
replaced by :func:`markupsafe.escape`.
:class:`~widgets.core.HTMLString` is removed, replaced by
:class:`markupsafe.Markup`. :pr:`400`

package. :issue:`385`, :pr:`403`
- :class:`~fields.core.Label` text is escaped before rendering.
:issue:`315`, :pr:`375`
- Email validation is now handled by an optional library,
``email_validator``. :pr:`429`

-------------

Released 2018-06-07

- :class:`~fields.StringField` only sets ``data = ''`` when form data
is empty and an initial value was not provided. This fixes an issue
where the default value wasn't rendered with the initial form.
:issue:`291, 401`, :pr:`355`

-----------

Released 2018-06-02

- Merged new and updated translations from the community.
- Passing ``data_`` args to render a field converts all the
underscores to hyphens when rendering the HTML attribute, not just
the first one. ``data_foo_bar`` becomes ``data-foo-bar``. :pr:`248`
- The :class:`~validators.UUID` validator uses the :class:`uuid.UUID`
class instead of a regex. :pr:`251`
- :class:`~fields.SelectField` copies the list of ``choices`` passed
to it so modifying an instance's choices will not modify the global
form definition. :pr:`286`
- Fields call :meth:`~fields.Field.process_formdata` even if the raw
data is empty. :pr:`280`
- Added a :class:`~fields.MultipleFileField` to handle a multi-file
input. :class:`~fields.FileField` continues to handle only one
value. The underlying :class:`~widgets.FileInput` widget gained a
``multiple`` argument. :pr:`281`
- :class:`~fields.SelectField` choices can contain HTML (MarkupSafe
``Markup`` object or equivalent API) and will be rendered properly.
:pr:`302`
- ``fields.TimeField`` and ``html5.TimeField`` were added. :pr:`254`
- Improved :class:`~validators.Email`. Note that it is still
unreasonable to validate all emails with a regex and you should
prefer validating by actually sending an email. :pr:`294`
- Widgets render the ``required`` attribute when using a validator
that provides the ``'required'`` flag, such as
:class:`~validators.DataRequired`. :pr:`361`
- Fix a compatibility issue with SQLAlchemy 1.2 that caused
:class:`~ext.sqlalchemy.fields.QuerySelectField` to fail with
``ValueError: too many values to unpack``. :pr:`391`
