Of course, InvoicePlane-it is the Italian fork.
What I mean is that we are prob. going to anticipate these fixes into 1.5.10, and they are going to be used and tested.
So whenever works for 1.6.0 will start, it can be a base for 1.6.0 for the international version. Just that.
I can make a second PR for the 1.6.0 branch myself when I finish on the other end.
