Highly appreciated and anticipated.
Thank you very much

The github action pipeline fails as python 3.7 is no longer supported by them.
I just checked and python 3.8 also reached the end of life, so we should probably remove 3.7 and 3.8

seems like we're not compatible with sklearn >= 1.6.

Quick fix would be to specify this in requirements.txt and create an issue (or properly fit it).

I'm currently working on a rather big change that should add type hinting, update all dependencies and re-work the tooling including a pipeline that does type checking and format checking etc.

Not sure when this will be done but it will fix compatibility issues as well

I've added support. Closing this now.
