Comment (by Gabriele Bozzola):

I have a branch with version 1.4.1 that adds support for Python 3.12, while maintaining support for 3.7. The mininum version for development was bumped to 3.8.

https://github.com/Sbozzolo/kuibit/tree/141

If someone can give it a try and give me a green light, I can make a release.
