- multi-instances support is removed from the parameter definitions. - XRCE_DDS_AG_IP allows to define the agent IP when udp transport is used. The parameter is used by default if the module is started without the -h argument. - XRCE_DDS_PRT allows to define the agent listning udp port when the udp transport is uded. The parameter is used by default if the module is started without the -p argument. - Tools/convert_ip.py assists in converting ips in decimal dot notation into int32 notation.
