2.0.0 - 11/06/2016

django-reversion was first released in May 2008, and has been in active development ever since. Over this time it's developed a certain amount of cruft from legacy and unused features, resulting in needless complexity and multiple ways of achieving the same task.

This release substantially cleans and refactors the codebase. Much of the top-level functionality remains unchanged or is very similar. The release notes are divided into subsections to make it easier to find out where you need to update your code.

This release includes a migration for the Version model that may take some time to complete.

General improvements

Dramatically improved performance of version lookup for models with a non-integer primary key (@etianen, @mshannon1123).
Documentation refactor (@etianen).
Test refactor (@etianen).
Minor tweaks and bugfixes (@etianen, @bmarika, @ticosax).

Admin

Fixed issue with empty revisions being created in combination with RevisionMiddleware (@etianen).

Breaking: Removed reversion_format property from VersionAdmin (@etianen).

Use VersionAdmin.reversion_register instead.

class YourVersionAdmin(VersionAdmin):

    def reversion_register(self, model, **options):
        options["format"] = "yaml"
        super(YourVersionAdmin, self).reversion_register(model, **options)

Breaking: Removed ignore_duplicate_revisions property from VersionAdmin (@etianen).

Use VersionAdmin.reversion_register instead.

class YourVersionAdmin(VersionAdmin):

    def reversion_register(self, model, **options):
        options["ignore_duplicate_revisions"] = True
        super(YourVersionAdmin, self).reversion_register(model, **options)

Management commands

Breaking: Refactored arguments to createinitialrevisions (@etianen).

All existing functionality should still be supported, but several parameter names have been updated to match Django coding conventions.

Check the command --help for details.
Breaking: Refactored arguments to deleterevisions (@etianen).

All existing functionality should still be supported, but several parameter names have been updated to match Django coding conventions, and some duplicate parameters have been removed. The confirmation prompt has been removed entirely, and the command now always runs in the --force mode from the previous version.

Check the command --help for details.

Middleware

Added support for using RevisionMiddleware with new-style Django 1.10 MIDDLEWARE (@etianen).
Middleware wraps entire request in transaction.atomic() to preserve transactional integrity of revision and models (@etianen).

View helpers

Added reversion.views.create_revision view decorator (@etianen).
Added reversion.views.RevisionMixin class-based view mixin (@etianen).

Low-level API

Restored many of the django-reversion API methods back to the top-level namespace (@etianen).
Revision blocks are now automatically wrapped in transaction.atomic() (@etianen).
Added for_concrete_model argument to reversion.register() (@etianen).
Added Version.objects.get_for_model() lookup function (@etianen).
Added reversion.add_to_revision() for manually adding model instances to an active revision (@etianen).
Removed Version.object_id_int field, in favor of a unified Version.object_id field for all primary key types (@etianen).
Breaking: reversion.get_for_object_reference() has been moved to Version.objects.get_for_object_reference() (@etianen).
Breaking: reversion.get_for_object() has been moved to Version.objects.get_for_object() (@etianen).
Breaking: reversion.get_deleted() has been moved to Version.objects.get_deleted() (@etianen).
Breaking: Refactored multi-db support (@etianen).

django-reversion now supports restoring model instances to their original database automatically. Several parameter names have also be updated to match Django coding conventions.

If you made use of the previous multi-db functionality, check the latest docs for details. Otherwise, everything should just work.
Breaking: Removed get_ignore_duplicates and set_ignore_duplicates (@etianen).

ignore_duplicates is now set in reversion.register() on a per-model basis.
Breaking: Removed get_for_date() function (@etianen).

Use get_for_object().filter(revision__date_created__lte=date) instead.
Breaking: Removed get_unique_for_object() function (@etianen).

Use get_for_object().get_unique() instead.
Breaking: Removed signal and eager_signals argument from reversion.register() (@etianen).
To create revisions on signals other than post_save and m2m_changed, call reversion.add_to_revision() in a signal handler for the appropriate signal.
```
from django.dispatch import receiver
import reversion
from your_app import your_custom_signal

@reciever(your_custom_signal)
def your_custom_signal_handler(instance, **kwargs):
    if reversion.is_active():
        reversion.add_to_revision(instance)
```
This approach will work for both eager and non-eager signals.
Breaking: Removed adapter_cls argument from reversion.register() (@etianen).

Breaking: Removed reversion.save_revision() (@etianen).

Use reversion.add_to_revision() instead.

import reversion

with reversion.create_revision():
    reversion.add_to_revision(your_obj)

Signals

Breaking: Removed pre_revision_commit signal (@etianen).

Use the Django standard pre_save signal for Revision instead.
Breaking: Removed post_revision_commit signal (@etianen).

Use the Django standard post_save signal for Revision instead.

Helpers

Breaking: Removed patch_admin function (@etianen).
Use VersionAdmin as a mixin to 3rd party ModelAdmins instead.
```
@admin.register(SomeModel)
class YourModelAdmin(VersionAdmin, SomeModelAdmin):

    pass
```
Breaking: Removed generate_diffs function (@etianen).

django-reversion no supports an official diff helper. There are much better ways of achieving this now, such as django-reversion-compare.

The old implementation is available for reference from the previous release.
Breaking: Removed generate_patch function (@etianen).

class YourModel(models.Model):

    pass

from reversion import revisions as reversion

# Use low-level API methods from the revisions namespace.
@reversion.register
class YourModel(models.Model):

    pass

Breaking: Updated the location of http://django-reversion.readthedocs.org/en/latest/signals.html.

Prior to this change, you could access the reversion signals using the following import:

# Old-style import for accessing the reversion signals
import reversion

# Use signals from the reversion namespace.
reversion.post_revision_commit.connect(...)

In order to support Django 1.9, the reversion signals have been moved to the following import:
