Changelog

Sourced from django-mptt's changelog.

========== Change log

Next version

0.16

• Fixed get_cached_trees if there are multiple trees in the queryset.
• Added support for Python 3.12, Django 5.0.
• Added codespell and ruff checks to the CI.
• Fixed rebuilding using custom managers not named objects.

0.15

• Since I unfortunately still depend on django-mptt in prehistoric projects I took it upon me to make it runnable again. This doesn't mean I want to maintain the package.
• Added Django 4.2.
• Dropped Python < 3.9, Django < 3.2.
• Started using ruff and more rules.
• Dropped the index_together check on Django 5 and better. Django 5 only supports Meta.indexes.
• Optimized tree rebuilding.
• Added support for the Django admin theme switcher.
• Switched to hatchling.

0.14

• Merged the docs/upgrade.rst file into the main CHANGELOG.rst.
• Fixed the Sphinx autodoc configuration to also work locally. Ensured that readthedocs is able to build the docs again.
• Fixed a bug where DraggableMPTTAdmin assumed that the user model's primary key is called id.
• Ensured that we do not install the tests.myapp package.
• Added dark mode support to the draggable model admin.
• Started using pre-commit, for the fun of it.

0.13

• MARKED THE PROJECT AS UNMAINTAINED, WHICH IT STILL IS
• Reformatted everything using black, isort etc.
