Changelog
=========

(Unreleased)
~~~~~~~~~~~~

5.0.1 (2023-10-26)
~~~~~~~~~~~~~~~~~~

* Fix the package metadata to properly reflect the right Django and Python version requirements
  Release 5.0.0 improperly stated its Django bounds as >=3.2, so people installing without bounds will end up on a version that won't work.

5.0.0 (2023-10-24)
~~~~~~~~~~~~~~~~~~
* **Backwards icompatible:** Rename the (``content_type``, ``object_id``) index on ``TaggedItem``.
  It is very unlikely for this to affect your code itself, and a migration will rename the index. This should not cause any downtime according to my research (Postgres does not lock the table for index renames, and Oracle holds a tiny lock to do it, and the change is only to the metadata, so is not dependent on table size).

* **Backwards incompatible:** Remove the ``.indexed_together`` and ``.unique_together`` attributes on ``TaggedItem``

  We are instead using ``constraints`` and ``indexes`` to set up these properties.
* Remove support for Django 3.2.
* Remove usage of deprecated APIs for Django 4.2
* Remove support for Python 3.7 (no code changes involved)
* Fix ``tag_kwargs`` and ``TAGGIT_CASE_INSENSITIVE=True`` discrepency.

4.0.0 (2023-05-04)
~~~~~~~~~~~~~~~~~~
* Remove Python 3.6 support (no code changes occurred, but we no longer test this release).
* Remove Django 4.0 support (no code changes occurred, but we no longer test this release).
* Add Django 4.2 support.

3.1.0 (2022-11-08)
~~~~~~~~~~~~~~~~~~

* Add Python 3.11 support (no code changes were needed, but now we test this release).
* Add Django 4.1 support (no code changes were needed, but now we test this release).
* Fixed an issue where object caches would not be properly cleared after updating tags, leading
  to stale reads in cases where ``prefetch_related`` is used.
* Change ``TagListSerializerField`` to be a subclass of ``ListField``. This should improve support for API document generation. This change should not affect API behavior, but might affect metaprogramming code, so please procede carefully during this update.

3.0.0 (2022-05-02)
~~~~~~~~~~~~~~~~~~

* **Backwards incompatible:** Tag slugification used to silently strip non-ASCII characters
  from the tag name to make the slug. This leads to a lot of confusion for anyone using
  languages with non-latin alphabets, as well as weird performance issues.

  Tag slugification will now, by default, maintain unicode characters as-is during
  slugification. This will lead to less surprises, but might cause issues for you if you are
  expecting all of your tag slugs to fit within a regex like ``[a-zA-Z0-9]`` (for example in
  URL routing configurations).

  Generally speaking, this should not require action on your part as a library user, as
  existing tag slugs are persisted in the database, and only new tags will receive the
  enhanced unicode-compatible slug.

  If you wish to maintain the old stripping behavior, set the setting
  ``TAGGIT_STRIP_UNICODE_WHEN_SLUGIFYING`` to ``True``.

  As a reminder, custom tag models can easily customize slugification behavior by overriding
  the ``slugify`` method to your business needs.

`` Drop Django 2.2 support.

2.1.0 (2022-01-24)
~~~~~~~~~~~~~~~~~~

* Add Python 3.10 support.
* Add Django 4.0 support.
* Drop Django 3.1 support.


2.0.0 (2021-11-14)
~~~~~~~~~~~~~~~~~~

* **Backwards incompatible:** ``TaggableManager.set`` now takes a list of tags
  (instead of varargs) so that its API matches Django's ``RelatedManager.set``. Example:

  - previously: ``item.tags.set("red", "blue")``
  - now: ``item.tags.set(["red", "blue"])``

* Fix issue where ``TagField`` would incorrectly report that a field has changed on empty values.
* Update Russian translation.
* Add Persian translation
* Fix issue for many languages where content types were not being properly translated.
* Provide translators additional context regarding strings in TagBase model.

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

* Update compiled Danish translation.


1.5.0 (2021-06-30)
~~~~~~~~~~~~~~~~~~

* Vendor in the `django-taggit-serializer` project (under `taggit.serializers`).

1.4.0 (2021-04-19)
~~~~~~~~~~~~~~~~~~

* Add Python 3.9 support.
* Remove Python 3.5 support.

1.3.0 (2020-05-19)
~~~~~~~~~~~~~~~~~~

* 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.

* Added support for Django 3.0.

* 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``.

0.24.0 (2019-02-19)

* Fixed a race condition in ``TaggableManager``.
