Form rendering accessibility
----------------------------
In order to aid users with screen readers, and other assistive technology, new
``<div>`` based form templates are available from this release. These provide
more accessible navigation than the older templates, and are able to correctly
group related controls, such as radio-lists, into fieldsets.
The new templates are recommended, and will become the default form rendering
style when outputting a form, like ``{{ form }}`` in a template, from Django
5.0.
In order to ease adopting the new output style, the default form and formset
templates are now configurable at the project level via the
:setting:`FORM_RENDERER` setting.
See :ref:`the Forms section (below)<forms-4.1>` for full details.

as the template implements ``<fieldset>`` and ``<legend>`` to group related
inputs and is easier for screen reader users to navigate.
The div-based output will become the default rendering style from Django 5.0.
* In order to smooth adoption of the new ``<div>`` output style, two
transitional form renderer classes are available:
:class:`django.forms.renderers.DjangoDivFormRenderer` and
:class:`django.forms.renderers.Jinja2DivFormRenderer`, for the Django and
Jinja2 template backends respectively.
You can apply one of these via the :setting:`FORM_RENDERER` setting. For
example::
FORM_RENDERER = "django.forms.renderers.DjangoDivFormRenderer"
Once the ``<div>`` output style is the default, from Django 5.0, these
transitional renderers will be deprecated, for removal in Django 6.0. The
``FORM_RENDERER`` declaration can be removed at that time.
* If the new ``<div>`` output style is not appropriate for your project, you should
define a renderer subclass specifying
:attr:`~django.forms.renderers.BaseRenderer.form_template_name` and
:attr:`~django.forms.renderers.BaseRenderer.formset_template_name` for your
required style, and set :setting:`FORM_RENDERER` accordingly.
For example, for the ``<p>`` output style used by :meth:`~.Form.as_p`, you
would define a form renderer setting ``form_template_name`` to
``"django/forms/p.html"`` and ``formset_template_name`` to
``"django/forms/formsets/p.html"``.
* The new :meth:`~django.forms.BoundField.legend_tag` allows rendering field
labels in ``<legend>`` tags via the new ``tag`` argument of
:meth:`~django.forms.BoundField.label_tag`.
