Has anyone tried QEMU 4.2?

Has anyone tried using QEMU 4.2 yet? Is it stable? Being the lazy type, I’m considering using the PPA referenced here:

https://launchpad.net/~jacob/+archive/ubuntu/virtualisation (yes, I’m on Ubuntu Eoan)

Does anyone have experience with this PPA provider? Just testing the water before diving in, anyone have feedback? Sharks or mermaids?
