Django 1.8 was released back on April 1 and there’s a few things to be aware of when making the upgrade…
1) django.contrib.formtools has been removed. If you were making use of it, grab the new 3rd party library.
2) A good chunk of the django-secure third-party library has been integrated into Django as part of the new django.middleware.security.SecurityMiddleware. Read up on how to configure the new settings.
3) Django now supports multiple template engines with built-in support for the Django template language and for Jinja2. As part of this change you’ll need to update your template settings (for now Django will still use your existing settings, but they are deprecated and will go away with a future release).
4) Django Compressor was incompatible with Django > 1.7. This is now rectified with the recent release of version 1.5.
As always, definitely read the release notes as there’s lots of new stuff along with minor changes and bug fixes in this release.
