It broke for me too.
Monitor's not working.
In fact, I'm booting into black screen.
There's an additional issue is that the USB drive I have attached is not recognized at boot and the boot is blocked for 1.5min b/c of this. But even after disabling it in /etc/fstab - just black screen.
Works with 4.15.0-43-generic.
