We are busy preparing the next release of OpenDDS. We estimate a May release but will not release until the code is ready.
We are currently planning the following feature enhancements for the new release, though this list is subject to change:

• Use multiple DCPSInfoRepos
• New QoS features
• dispose() notifications
• IPv6 support
• Improved memory management
• Multicast transport improvements
• Changeable QoS policies
• Documentation updates
• New tests and examples
