Thanks for your help on this.

I feel like we ought to add a specific tox env to test minimum versions of dependencies, like we did on webargs for instance, to be sure we don't use new Flask features without realizing it because the tests only test the latest version.

https://github.com/marshmallow-code/webargs/blob/dev/tox.ini

If you'd like to tackle this, you're more than welcome. Otherwise, let's just set 4.0 as max as per my comment and merge this for now. The minimum dependency versions test issue shouldn't block this.

[lafrech]

I don't mind, but out of curiosity, is this automatic reordering from a tool like PyCharm or something?

[lafrech]

I'd set the max to 4.0. Things shouldn't break in between.

Superseded by #576.

Thanks anyway.
