Django 4.1.x deprecation errors (default_app_config)

[sergeyklay]

Hello,

There is upgrading warning I would like avoid to. After upgrading to Django 3.2 and using Django-Solo 1.1.5 raise this deprecation:

django/apps/registry.py:91: RemovedInDjango41Warning: 'solo' defines default_app_config = 'solo.apps.SoloAppConfig'. 
Django now detects this configuration automatically. You can remove default_app_config.
  app_config = AppConfig.create(entry)

It will take a while before Django 4.1.x is here, and as far as I understand, this version will remove support of default_app_config. For more see Automatic AppConfig discovery for Django 3.2. I hope it is trivial. Please let me know if I can help you with this.
