I am afraid it's a bit early to drop Python 3.5 support. It is supported by Django 2.2 which is LTS until 2022.
Any reason we can't stick with the current pytest versions ?

[auvipy]

if we explicitly use six and still update the versions everything will work. there is a related linked PR too

#7707

[xordoquy]

Well, pytest 6.2 release notes says they require 3.6+

[xordoquy]

ok, never mind. Python 3.5 is EOL, let's just move forward.

[auvipy]

IMHO drf master should 3.6+ but it's up to you. as a downstream extension keep supporting and EOL py version is a maintenance burden IMHO. can we somehow pull the master branch here through Github?

[xordoquy]

to rebase ? I don't think so. I'll do that later if it's not already done before
