I just figured out how to do it, it's very clumsy and much slower than the old way, aaargh. But it does work and sometimes takes a few attempts.
I cntrl middle drag from the output of one node's yellow/orange out to the input yellow/orage button. it will make default connections but sometimes bring up connection editor, if that happens; simply close CE and the default connections are made.
The older way you could drag (zoomed out) only nodes anywhere and make connections. Much faster and didn't seem to be confused at times.
To be fare, they've made great improvements in other area like being able to highlight a node and see how the downstream connections are affecting the network to that point which is handy. But they always seem to make a couople steps forward and couple steps backwards.
