v3.x expired License, Upgrade to v4.x and get 3.x updates?
 

I currently hold an expired 3.x license. I'd like to get my board up to the latest fixes on v.3 before I jump onto v.4
If i purchase an upgrade to v4, will I still be eligible for latest 3.x builds?
It doesn't make sense for me to purchase a 3 month 3x license and than purchase a v4 license.
