Firefox changes its major number on a 6 weeks (maybe 4 weeks now) 
schedule. We change ours every 110 weeks historically. If we go to 3 
now, we will be at 10 in 14 years.

It is more like LibreOffice than Firefox.

But I am not going to argue more than that.
I guess I have to shelve my proposal to rename ourselves to "LyX Office 
Studio", then.
