[ISSUE OTHERWISE!!] [SEE NEW API] must bump major version to 1

[damianatorrpm]

Qt6 and 5.15 optionally already works the new way will require no minor version to be specified
and 0 is not a valid major version
import SortFilterProxyModel 0

sorry for caps but I see it to often that people don't read the actual description,
except when a statement like ISSUE OTHERWISE!! is made.
There is an issue otherwise.
