https://docs.djangoproject.com/en/4.2/releases/4.2/#miscellaneous

The undocumented django.http.multipartparser.parse_header() function is removed. Use django.utils.http.parse_header_parameters() instead.

It looks like DRF 3.13 is not compatible with Django 4.2.

• Replace parse_header (removed in Django 4.2) with parse_header_parameters encode/django-rest-framework#8540
• When will Django4.2 be supported? encode/django-rest-framework#8942

[johnthagen]

@Andrew-Chen-Wang It looks like only DRF 3.13 is incompatible with Django 4.2.

The way the matrix is currently set up in GitHub Actions and tox-gh-actions runs "every Python version against every Django version against every DRF version". This makes it harder to exclude a single environment (e.g. exclude Django 4.2 on DRF 3.13).

djangorestframework-simplejwt/.github/workflows/test.yml

Lines 17 to 20 in aa077a4

	matrix:
	python-version: ['3.7', '3.8', '3.9', '3.10', '3.11']
	django-version: ['3.2', '4.0', '4.1']
	drf-version: ['3.10', '3.11', '3.12', '3.13', '3.14']

djangorestframework-simplejwt/tox.ini

Lines 16 to 26 in aa077a4

	[gh-actions:env]
	DJANGO=
	3.2: dj32
	4.0: dj40
	4.1: dj41
	DRF=
	3.10: drf310
	3.11: drf311
	3.12: drf312
	3.13: drf313
	3.14: drf314

It is possible to be more specific/explicit using tox-gh-actions for example:

• https://github.com/jazzband/django-dbbackup/blob/master/tox.ini#L22

But I'm not sure what your preference here is.

[dpgraham4401]

@johnthagen An option would be to configure the GH Actions test workflow to skip matrix configuration matching a certain criteria with the jobs.<job_id>.strategy.matrix.exclude keyword.

    matrix:
      python-version: ['3.7', '3.8', '3.9', '3.10', '3.11']
      django-version: ['3.2', '4.0', '4.1', '4.2']
      drf-version: ['3.10', '3.11', '3.12', '3.13', '3.14']
      exclude:
        - django-version: '4.2'
          drf-version: '3.13'

I haven't tested, but should provide the desired outcome.

Thanks @dpgraham4401! That was exactly what was needed. Implemented in d74835a.

@Andrew-Chen-Wang this PR is now ready for review. Thanks.

Thank you everyone for helping out. This looks great!
