Important new features

GRC Bus Ports (Nicholas McCarthy)

Bus ports in the GNU Radio Companion (GRC) allow ganging block input
or output ports into a single port for display and connections. This
simplifies flowgraph entry when dealing with blocks that work with an
arbitrary number of streams.

For further information, see:

http://gnuradio.org/redmine/projects/gnuradio/wiki/Busports
