From what I understand, starting with V13 personal licenses will include 1 year free upgrades. I thought V12 licenses younger than 1 year will work with V13, but that's not the case. I like the IDE, but I will stick with v12 for now.

1 year of updates not upgrades. Otherwise you'd only "need" to buy an upgrade every other year.
