Messy releases

[ziima]

When using major.minor.bugfix versions, a change in supported Django versions should come with the minor version, not the bugfix version change. Current status of 0.5.1 not working with Django 1.10 and 0.5.4+ working with Django 1.11 causes a spurious errors to occur, since it's not generally expected that such change would occur as part of the bugfix release.
