Apparently we are almost ready to release and one latest round of final
validation was pending.
Christophe, any news on this front?

I was going to say that I agree, but I believe Patrik might be right.
Without this patch we load the 1.06 while with this patch we start
loading only the 1.07 that is not available.
Although 1.06 might have issues the failures would be different. So or
we blacklist 1.06 with a separated patch and then merge this one or we
release the 1.07 before.
