@nkprince007 pillow is required for what?

[nkprince007]

@ghoshbishakh Pillow v4.0(python3.6) is required for ImageField.

[ghoshbishakh]

@nkprince007 is it required for django 1.8 on py 3.6 or django 1.11?

[nkprince007]

django 1.8 on python3.6 (fresh install of festcms)

[ghoshbishakh]

@nkprince007 okay. So we need to add a test for django migrations in travis

[ghoshbishakh]

@ankan17 can you possibly take up this task?

[ankan17]

Okk I'll try @ghoshbishakh

[ghoshbishakh]

@ankan17 you will be facing problems with python social auth.

Just migrate that to the new version https://github.com/python-social-auth/social-app-django

[ankan17]
