Version 2.2.1
-------------
Released on June 7th, 2018
- :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.

Version 2.2
-----------
Released on June 2nd, 2018
- 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``. (`#248`_)
- The :class:`~validators.UUID` validator uses the :class:`uuid.UUID`
class instead of a regex. (`#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. (`#286`_)
- Fields call :meth:`~fields.Field.process_formdata` even if the raw
data is empty. (`#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. (`#281`_)
- :class:`~fields.SelectField` choices can contain HTML (MarkupSafe
``Markup`` object or equivalent API) and will be rendered properly.
(`#302`_)
- :class:`~fields.TimeField` and
:class:`html5.TimeField <fields.html5.TimeField>` were added.
(`#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. (`#294`_)
- Widgets render the ``required`` attribute when using a validator
that provides the ``'required'`` flag, such as
:class:`~validators.DataRequired`. (`#361`_)
- Fix a compatibility issue with SQLAlchemy 2.1 that caused
:class:`~ext.sqlalchemy.fields.QuerySelectField` to fail with
``ValueError: too many values to unpack``. (`#391`_)
