Features added and bugs/fixes in this OpenDDS version:
(This is an excerpt of the NEWS, for full change information see the NEWS and the ChangeLog within the source distribution)

Additions:

• Support later (>= 4.7) versions of GCC compilers, and later (>= 2.0a) builds of TAO. Configure script now downloads 2.2a by default.
• Added IDL compiler support for typedef of string fields within unions.
• Added Java IDL compiler support for struct forward declarations.
• Updated UML design diagrams to reflect current code base.

Fixes:

• DCPSInfoRepo no longer informs a subscriber about a crashed or killed publisher. This made associations of current publishers and subscribers delayed until timeout was reached.
• Fixed deadlock condition in send_delayed_notifications() resulting from multiple datawriters.
• Fixed deadlock in DataLinkSet::send_control().
• Fixed deadlock in WaitSet::wait() and DataReaderImpl::data_received().
• Fixed multicast transport with multiple participants in a single process.
• Fixed parsing of -ReassociateDelay argument by DCPSInfoRepo.
• Fixed crash of long-lived zero-copy sequence when it is destroyed and crash of zero-copy sequence accessing released instances.
• Fixed unprotected access to DataWriterImpl::reader_info_ and TransportSendStrategy::pkt_chain_.
• Fixed multiple RTPS crashes when participant is being deleted.
• Fixed RTPS crash when a data reader is being deleted.
• Fixed problem for non-unique repo ids for multicast when multiple (non-federated) DCPSInfoRepos are used on the same network.
• Fixed crash caused by back-pressure in transport causing the most recent sample for an instance to be dropped.
• Fixed error in reconstruction logic for fragmentation of udp and multicast transport packets.
• Fixed PublisherImpl and SubscriberImpl to properly set a DataWriterImpl or DataReaderImpl entity's deleted flag during deletion to allow association checks to properly identify entities that are being deleted and not proceed in association.
• Fixed problem for persisted DCPSInfoRepo where persisted participants were never dissociating.
• Fixed activity improperly occuring when a partipant is being deleted that caused pure virtual function calls. In one case, waiting now takes place during deletion of a data writer until all control messages sent during unregistration of instances are account for. In another case fixed so TransportSendControlElement will delete itself before it reports to the listener that the message has been delivered/dropped.

Tests:

• Many updates to make test results more deterministic.
• Added Reliability test.
• Added ManyToMany test to test associations with additional participants, publishers, subcribers, data readers and data writers.
• Added PersistentInfoRepo test.
• Restored thrasher medium and high test cases.
• Rewrite Priority test to make it verify proper QOS functionality.
• Rewrite LargeSample test to make it verify message contents are as expected.
