How do I scale everything up or upgrade to XFCE 4.14?

I’m using a 4K monitor which makes everything really small when XFCE is set at a 4K resolution. I want to scale up the icons and text, but from my understanding that’s not available in XFCE below version 4.14. I checked my XFCE version and it is 4.12 (I’m on the latest Whonix). So how do I scale everything up or upgrade to XFCE 4.14?
