@Anish9901 FYI there's a package called drf-friendly-errors-django-4 that should be a drop in replacement for drf-friendly-errors, I found it when testing 0.1.4 installation with 3.11, here's my notes.

https://pypi.org/project/drf-friendly-errors-django-4/

[Anish9901]

I did try that package @kgodey, but it has some additional changes that conflicts with our current error codes and hence breaks some of our tests.

[Anish9901]

I'm planning to handle doc changes regarding python version in #3445, as build from scratch is the only section in the docs where we mention python versions.

[kgodey]

@Anish9901 Please handle the doc changes in this PR, otherwise the docs won't be in sync with the code when this is merged. Also #3445 doesn't appear to be in this release, should it be?

@kgodey Regarding drf-friendly-errors, this is a temporary measure until we remove that dependency entirely.
