v4 Special Upgrade Pricing?

I purchased FlowHeater v3.x July 30, 2014 using a special BitsDuJour offer with 1 year of updates. I see that v4 was just released. Normal upgrade pricing is $59. Wonder if FlowHeater might have a v4 special upgrade price coming soon? Many companies offer temporary special pricing when a new version comes out.

Thanks,

Hi,
My Sequential invoice number is e5-DE-2013-00000788942. How much do I need to pay to get the upgrade to version 4? (I could not subscribe to the newsletter, the error msg was in German and therefore I don't know the price which you said stated in the newsletter). Thanks for your help
