I have been using version 3.2 since Beta. Deployed on a production application, so far without a single problem.
I highly praise Automatic AppConfig discovery and BigAutoField for pkey.
I highly recommend the transition to Django 3.2
The ability to customize the type of auto-created primary keys is also one step towards fixing one of the long-standing issues in Django: https://code.djangoproject.com/ticket/56
