Em Client 8 upgrade fee

I joined EM Client and after a trial period I purchased Pro to get updates and help,now I have received a promotion for EM Client 8 to purchase at a price or a life time upgrade for a higher price !
I understood when I paid for Pro that was it for upgrades, deceiption by EM Client !

I got the same email. WAIT. Your version of EM Client will tell you an update is out there and ask if you want to update. Took mine about a week after the email to tell me about the update.
