If I understand correctly this bugzilla thread describes implementing 
two distinct multi-monitor configurations

1. Two (or more) monitors form a single larger display. When switching 
workspaces they switch as a single whole.
This is the previous action (prior to 12th March or so)

2. Two monitors operate independently Only the primary display changes 
when switching. The secondary (and I guess further monitors) is (are) 
static.
This is the new action.

So how do I configure for configuration 1 now? I couldn't see how this 
is selectable.
