Coverage seems decreased maybe some code specific for django 3.1 are not used anymore ?

[tim-schilling]

The codecov percentage is flaky. We're likely to drop it as per #1542

[tim-schilling]

Let me v3.2.4 out the door and I'll merge this.

I think we could even drop Django 2.2, at least soon.

django-upgrade may help with dropping old code afterwards.

"I think we could even drop Django 2.2, at least soon."

Not before April 2022 https://www.djangoproject.com/download/#supported-versions

I think we can drop support for Django < 3.2. Here is a comment from Tim about this jazzband/django-hosts#141 (comment)

[pauloxnet]

No, once Django 4.0 is out, it's time to drop support for all versions older than the most recent LTS. Otherwise, it could require ugly shims to add 4.0 support (which removes a lot of deprecated things). This is outlined in https://www.djangoproject.com/weblog/2015/jun/25/roadmap/.

Thanks for pointing to this @timgraham explanation. 👍
