STACK: Problems with cartesian_products

STACK: Problems with cartesian_products

We plan to update to STACK 4.4, so we tested a bit and found out the following:

cartesian_product({a,c},{b,d}) 

works fine with STACK Version 2020120600 

in tests with  STACK version 2023010400 it delivers 

The value $B is not of type LIST

Can I do something, or is it a bug in STACK/Maxima ?

Best regards

Frauke

It seems to be a problem after maxima version 5.43, which introduced a lisp function named "cartesian-product" which the maxima function `cartesian_product` calls and stackmaxima overwrites with its own incompatible `cartesian-product` version.
I have opened an issue on the moodle stack issue tracker here: https://github.com/maths/moodle-qtype_stack/issues/924
