Release notes and new features in this release:

New Core Middleware Features

• Multicast Support: The new concept of multi-parallel bindings in the communication framework of NMM allows the integration of custom transport strategies that can employ a one-to-many communication transport mechanism (such as IP multicast) to transmit messages from one sender node to many receiver nodes within a single NMM flow graph.
• Error Handling: Improved error handling in communication framework and extended the API of the communication framework to allow for advanced error diagnostics and specification of network timeouts for individual connections. Robustness of the NMM registry service has been significantly improved by making use of these new features.
• IP Address Support: It is now possible to specify IP addresses instead of host names when specifying the location of a node or connecting to a named service. This allows NMM to be used in a network without a DNS server or otherwise fixed host names.
• Raw UDP Streaming Support: The NetSourceNode can now be used to receive raw unicast or multicast UDP streams in addition to RTP streams. A RawUDPStrategy is also available for transmitting buffers between nodes of an NMM flow graph (unicast only).
• Optimised Communication Architecture: Performance of the communication framework of NMM has been improved, and the number of parallel threads has been significantly reduced.

New Services

• Directory Browser Service: An NMM-based service which can be used for browsing the file system of a remote host.
• Cronjob Service: An NMM-based service for starting timed tasks on a remote Linux system.
• Audio Handover Service: An synchronization service for seamless audio handover between distributed hosts.
• Scriptable User Interaction: A framework for script-based automated testing of interactive, distributed applications. See the document "Scriptable User Interaction" for details.
