Support for Django 2.0

Cleanerversion now comes with support for Django 2.0.

For bugs or extension suggestions, please open an issue or a Pull Request right away.

Support for EOL versions of Django (1.9 and 1.10) has officially been dropped.

Bugfix release

Several bugs in the admin view are now fixed.

Credits to @rossmechanic for contributing the fixes.

Compatibility for Django 1.9, 1.10 and 1.11

With version 2 of CleanerVersion, we support the overhauled ORM that came with Django 1.9.

By taking over all existing tests, we ensured feature-equivalence with former versions of CleanerVersion.

Please note, that version 2.x of CleanerVersion supports Django 1.9+, but not Django 1.8 and below.

Have fun.

prefetch_related fix

This release fixes an issue occurring when prefetching related objects with differing timestamps, as described in #129. Credits go to @brki
Additionally, testing was optimized. Thanks to @cclauss.

Handle deferred fields

Previously, it was impossible to use only() or defer() on a QuerySet for a Versionable Model; doing so resulted in an infinite loop.

This has been corrected, and some documentation about the limitations of this were added (specifically, it is not possible to clone or restore a version that has been fetched with deferred fields).

Going stable

• Starting with this version of CleanerVersion, Django versions < 1.8 are not supported anymore
• Support for UUID fields -> Read the upgrade notes (here) regarding this CleanerVersion release!!
• Bugfix: Avoid overlapping versions upon version restore
• Bugfix: prefetch_related with historic versions of reverse FK objects
• PLUS: we're going stable starting with this version! :)

Fixes and Django standard adoption

This release includes mainly bugfixes in the Admin interface (see PRs #106, #109, credits to @dunkelstern) and in the behaviour when working with Many-to-Many-relationships to self (see PR #112, credits to @brki).
You'll also notice a change that allows usage of Versionable objects that is closer to the Django default behaviour, by using objects as filter lookup values (see PR #113 for details, credits to @brki).

Restoring versions from Admin and bugfixes

This release extends the integration of CleanerVersion to Django's Admin interface.
Also, there are numerous fixes, like:

• reverse foreign key clearing now triggers a clone on related objects
• heterogeneous models (versioned and non-versioned ones) are now less error-prone

Bugfix on restoring versions

Check database for latest version when restoring a version
