Yes we do. The Flow's exploit for 3.67 works on 3.68 (the only thing this update fixed was a couple kernel exploits...that were only available on dev kits, not on stock Vita's), and is a full exploit chain (meaning, if you're on OFW 3.68, you can run the exploit).
It's just taiHen, meaning it's not a coldboot hack like Enso so it has to be run after every reboot, but we know it'll work for 3.68 no problem. The only true "con" is it's unlikely Enso support will arrive at all since the exploit that ran with was fixed on 3.67.
EDIT: @OP, it should be noted that 3.65 is the last OFW that can support Enso, so if you want coldboot hacks once The Flow releases his full exploit chain (sometime after September is the latest ETA), then leave your Vita on 3.65. If you don't mind having to reinstall the exploit after each reboot, then you can update to latest if you like. I, personally, would recommend sticking with 3.65.
