QtDBus has existed even on Windows since mid-Qt4 days (at least 4.5, probably 
since 4.4, possibly even 4.3, but I don't remember it working in 4.2). It's 
even been able to run on Windows CE since Qt 4.7. So it's not a new feature 
and that's why you don't find it in the new feature list.

The "new feature" was in Qt 5.4.0 when I added the ability for QtDBus to be 
compiled without having libdbus-1 present. Then I made that the default in 
5.4.1.

You still need the libdbus-1 DLL to be present in order to do anything with 
QtDBus. Without it, QDBusConnection will simply report it failed to connect.

The rewrite of QtDBus to work without libdbus-1 has been ongoing for a year, 
in my free time. I might finish it for Qt 5.9, but it's unlikely. It all 
depends on how widespread kdbus goes on Linux.
