Sorry, this software is incomplete and has many other bugs. I'm trying to keep up with Django 3.2, but so far I haven't had a chance. There are no plans to fix the bugs in 3.1.

The above exception was the direct cause of the following exception:

django==3.1 latest djfirebirdsql

Sorry I haven't maintained this for so long.

The django version keeps going up and up and up and I'm tired of it. I may pop back and fix things for the latest version of django, but I don't think I'll be able to do anything for a while.

I wish Django would do a builtin Firebird backend!
