Welcome to Oscar 2.0!
This is a significant release which includes a number of new features and backwards incompatible changes. In particular the way Oscar configures apps has been refactored and projects that have forked apps will need to follow the migration instructions in the documentaton.
Oscar 2.0 is compatible with Django 1.11, Django 2.1 and Django 2.2 as well as Python 3.5, 3.6 and 3.7. Support for Python 2.7 and Python 3.4 has been dropped.
