Oh, I see :)

the "loadbang" method is now called with a floating-point argument, so you
can do this:

static void loadbang_loadbang(t_loadbang *x, t_floatarg action)
{
    if (action == LB_LOAD)
        outlet_bang(x->x_obj.ob_outlet);
}

and just get the one bang.  This was done to allow "init" and "Close" bangs
as well.
