For me, gdm3 42.0-1ubuntu4 breaks Wayland entirely. There is no option to select a session left when logging in, and when I enter my password and press enter I'm left in an X11 session.
I only have machines with Intel graphics.
Reverting to 42.0-1ubuntu2 makes it work normally again (defaults to Wayland, with an option to select "Ubuntu on Xorg").
