Is the owrdpress developer bundle price a yearly or lifetime license?

Hi, I am considering your wordpress developer bundle offer, but it is not clear to me if I will receive security updates and if so, for how long. And if a renewal is necessary, will it come at a discount, please inform.

Also, the 4 links on you wordpress developer bundle page concerning multi domain, recurring payment, support, no date limits all link to unrelated product pages, please fix :-)

Thanks, S
