Changelog

3.7.0 (2024-05-29)

Dropped support for Django 3.2, which reached end-of-life on 2024-04-01 (gh-1344)
Removed the temporary requirement on asgiref>=3.6 added in 3.5.0,
now that the minimum required Django version is 4.2 (gh-1344)
Migrated package building from using the deprecated setup.py to using
pyproject.toml (with Hatchling as build backend);
setup.py has consequently been removed (gh-1348)
Added django>=4.2 as an installation dependency, to mirror the minimum version
tested in our CI (gh-1349)

3.6.0 (2024-05-26)

Support custom History Manager and QuerySet classes (gh-1280)
Renamed the (previously internal) admin template
simple_history/_object_history_list.html to
simple_history/object_history_list.html, and added the field
SimpleHistoryAdmin.object_history_list_template for overriding it (gh-1128)
Deprecated the undocumented template tag simple_history_admin_list.display_list();
it will be removed in version 3.8 (gh-1128)
Added SimpleHistoryAdmin.get_history_queryset() for overriding which QuerySet
is used to list the historical records (gh-1128)
Added SimpleHistoryAdmin.get_history_list_display() which returns
history_list_display by default, and made the latter into an actual field (gh-1128)
ModelDelta and ModelChange (in simple_history.models) are now immutable
dataclasses; their signatures remain unchanged (gh-1128)
ModelDelta’s changes and changed_fields are now sorted alphabetically by
field name. Also, if ModelChange is for an M2M field, its old and new
lists are sorted by the related object. This should help prevent flaky tests. (gh-1128)
diff_against() has a new keyword argument, foreign_keys_are_objs;
see usage in the docs under “History Diffing” (gh-1128)
Added a “Changes” column to SimpleHistoryAdmin’s object history table, listing
the changes between each historical record of the object; see the docs under
“Customizing the History Admin Templates” for overriding its template context (gh-1128)
Fixed the setting SIMPLE_HISTORY_ENABLED = False not preventing M2M historical
records from being created (gh-1328)
For history-tracked M2M fields, adding M2M objects (using add() or set())
used to cause a number of database queries that scaled linearly with the number of
objects; this has been fixed to now be a constant number of queries (gh-1333)

3.5.0 (2024-02-19)

Fixed FieldError when creating historical records for many-to-many fields with
to="self" (gh-1218)
Allow HistoricalRecords.m2m_fields as str (gh-1243)
Fixed HistoryRequestMiddleware deleting non-existent
HistoricalRecords.context.request in very specific circumstances (gh-1256)
Added custom_historical_attrs to bulk_create_with_history() and
bulk_update_with_history() for setting additional fields on custom history models
(gh-1248)
Passing an empty list as the fields argument to bulk_update_with_history() is
now allowed; history records will still be created (gh-1248)
Added temporary requirement on asgiref>=3.6 while the minimum required Django
version is lower than 4.2 (gh-1261)
Small performance optimization of the clean-duplicate_history command (gh-1015)
Support Simplified Chinese translation (gh-1281)
Added support for Django 5.0 (gh-1283)
Added support for Python 3.13 (gh-1289)
