Also: Allow override of database name and user in tests (important for me as I would have to mess with my PSQL and MySQL database users otherwise) Use dict.items instead of six.iteritems as it sporadically caused RuntimeError: dictionary changed size during iteration in Python 2.6 tests. Fix typo DNS to DSN Adds Python 3.5 to tox.ini Added an .editorconfig Import babel.dates in sqlalchemy_utils.i18n as an exception would be raised when using the latest versions of babel.
