Django-taggit

~~~~~~~~~~~~~~~~~~

* Model and field ``verbose_name`` and ``verbose_name_plural`` attributes are
now lowercase. This simplifies using the name in the middle of a sentence.
When used as a header, title, or at the beginning of a sentence, a text
transformed can be used to adjust the case.
* Fix prefetch_related when using UUIDTaggedItem.
* Allow for passing in extra constructor parameters when using
``TaggableManager.add``. This is especially useful when using custom
tag models.

~~~~~~~~~~~~~~~~~~

* **Removed** support for end-of-life Django 2.0 and 2.1.
* Added support for Django 3.0.
* Added support for Python 3.8.
* Moved ``TaggedItemBase.tags_for()`` to ItemBase.
* Replaced reference to removed Django's ``.virtual_fields`` with
``.private_field``.
* Added ``TextareaTagWidget``.

~~~~~~~~~~~~~~~~~~

* Added Finnish translation.
* Updated Chinese translation.
* Updated Esperanto translation.
* Fix ``form.changed_data`` to allow early access for a tags defined with
``blank=True``.

~~~~~~~~~~~~~~~~~~

* **Backwards incompatible:** Remove support for Python 2.
* Added ``has_changed()`` method to ``taggit.forms.TagField``.
* Added multi-column unique constraint to model ``TaggedItem`` on fields
``content_type``, ``object_id``, and ``tag``. Databases that contain
duplicates will need to add a data migration to resolve these duplicates.
* Fixed ``TaggableManager.most_common()`` to always evaluate lazily. Allows
placing a ``.most_common()`` query at the top level of a module.
* Fixed setting the ``related_name`` on a tags manager that exists on a model
named ``Name``.

~~~~~~~~~~~~~~~~~~~

* The project has moved to `Jazzband <https://jazzband.co/>`_. This is the
first release under the new organization. The new repository URL is
`<https://github.com/jazzband/django-taggit>`_.
* Added support for Django 2.2.
* Fixed a race condition in ``TaggableManager``.
* Removed method ``ItemBase.bulk_lookup_kwargs()``.
* Fixed view ``tagged_object_list`` to set ``queryset.model`` as
``ListView.model`` (was previously set as a ``ContentType`` instance).
* ``_TaggableManager`` and ``TaggableManager`` now always call the parent
class ``__init__``.
* Removed ``TaggableRel`` and replaced uses with ``ManyToManyRel``.

~~~~~~~~~~~~~~~~~~~

* **Backwards incompatible:** Remove support for Django < 1.11
* Added support for Django 2.1 and Python 3.7
* Moved TagWidget value conversion from TagWidget.render() to TagWidget.format_value()
