Type of Changes
Description
Using
default=[]
in Python 3.7 has the effect that values passed in for this parameter will be stored in the default list object. In subsequent runs (in the same process), the default value is wrongly prepopulated.Python 3.8 and above handle this situation better, but as we have to support Python 3.7 this fix is necessary.
