The biggest user-visible change in this version are the changes to dbus-cxx-xml2cpp, which now has much better code outputting capabilities. As part of this as well, the new way to create an adapter class involves running dbus-cxx-xml2cpp and implementing the auto-generated interface. This means that if the XML changes, the compiler will catch the difference between your code and the auto-generated code. The
documentation page has some more details on this.
