Yeah, I'll probably have some sort of mega release partay with a new Doors version, a new Portals version, and Elevators all at the same time. It might be after v9.
I've worked a bit this week to make my Add-Ons v9-compatible. The process is more complicated than I thought. Simple Add-Ons like weapons or vehicles might not take too much work, but complex Add-Ons like Doors, Portals, and Elevators will take a decent amount of work to port.
