# Upgrade Django v1.7.x

## Highlights for this release

- New [Django migrations](https://docs.djangoproject.com/en/dev/topics/migrations/) framework added
- Dropped support for Python 2.6
- [Reworked app framework](https://docs.djangoproject.com/en/1.8/ref/applications/#module-django.apps) (aka apps.py) including an [app-loading refactor](https://docs.djangoproject.com/en/dev/releases/1.7/#app-loading-refactor).
- New [Prefetch](https://docs.djangoproject.com/en/dev/ref/models/querysets/#prefetch-objects) option which allows you to dramatically improve the performance of `prefetch_related()` queries


## Upgrade Gotchas
- Features deprecated in Django 1.5 have [been removed](https://docs.djangoproject.com/en/dev/releases/1.7/#features-removed-in-1-7).
- If you're upgrading from something older than this, you should upgrade to at least the next [LTS release](https://upgradedjango.com/1.8/). It will have more security and bug fixes because of the [extended support](https://www.djangoproject.com/download/#ft2) period.
