OpenDDS version 3.9 is now available for download.
Please see http://download.ociweb.com/OpenDDS for the download.

An updated version of the OpenDDS Developer's Guide is available
from the same site in PDF format.

Updates in this OpenDDS version:

• Updated how DataWriter QoS is interpreted by internal data strucutres:
• RESOURCE_LIMITS.max_samples_per_instance controls total samples that can be
  stored per instance, independent of HISTORY
• HISTORY.depth controls number of samples (per instance) that will be made
  available to late-joining readers if DURABILITY is enabled
  • KEEP_ALL history uses max_samples_per_instance as its depth
• WriteDataContainer is more eager to remove samples that are no longer needed
• WriteDataContainer will not remove samples that are required to implement
  DURABILITY, hence if RELIABILITY is enabled this can block a write() just
  like other "no resource available" scenarios... read more

• Improved support for Safety Profile

• OpenDDS multicast transport (reliable mode) now guarantees in-order delivery

• Added a "default address" configuration parameter that sets an overall default
  for binding to a specific network interface

• Fixed bugs in transport framework, udp transport, InfoRepo discovery, static
  discovery, and the Liveliness and Durability QoS policies

Additions:

• Implements FACE Transport Services API v2.1, FACE safety base and
  FACE safety extended profiles (Future Airborne Capability Environment).
• Implements DDS 1.4 and RTPS 2.2.
• Support allocations from memory pool in safety profile builds. Introduced
  standard library containers and strings, as well as TAO sequences that
  allocate from this pool.
• To support FACE TS, the IDL struct DDS::SampleInfo has a new field
  "opendds_reserved_publication_seq" as an extension to the DDS specification.
• Updated opendds_idl for FACE support, moving some of the code-generation
  from tao_idl to opendds_idl when targeting FACE TS.
• Support IDL fixed type inside of DCPS_DATA_TYPE (used with FACE TS).
• Type-specific DataWriterImpl and DataReaderImpl are now templates. Code
  generation now introduces a typedef of these.
• Content filtering now supports modulus (MOD) operator as an extension.
• Added a static (configuration-based) discovery mechanism.
• RTPS Discovery is now supported when OpenDDS is built without built-in topics.
• RTPS Discovery has a new configuration parameter SedpLocalAddress which
  configures the rtps_udp transport used internally by discovery in the same way
  that local_address configures a user-created rtps_udp transport instance.
• Support non-default liveliness QOS in rtps_udp transport.
• Support wait_for_acknowledgements in rtps_udp transport.
• Support command line option -DCPSRTISerialization when integrating with RTI
  DDS using RTPS, to account for a different serialization algorithm.
• Configure script handles some cross-compile builds and safety profile.
• Support for new Visual Studio compilers (vc11, vc12, and vc14).
• Support for clang builds on Mac OS X.
• Removed support for old GCC compilers (<= 3.3).
• opendds_idl command-line option -Gitl is a replacement for -Gws. Wireshark
  dissector now reads ITL files, rather than .ini files.... read more

• This release includes the initial implementation of DDS Interoperability in OpenDDS, using the DDS-RTPS spec v2.1 from the OMG (formal/2010-11-01). RTPS support in OpenDDS consists of two main features:
  • A pluggable transport implementation, known as "rtps_udp" because it implements the UDP PSM of the DDS-RTPS spec. This is a peer of the existing OpenDDS-native transports: "tcp", "udp", and "multicast".
  • A new discovery mechanism for RTPS's distributed discovery. This can replace the DCPSInfoRepo in existing OpenDDS deployments.... read more

• Transport configuration has undergone a major redesign and any existing
  transport application code or transport configuration files need to be
  updated. See the Developer's Guide for details of the design. See
  $DDS_ROOT/docs/OpenDDS_3.0_Transition.txt for a description on how
  to migrate your applications to the OpenDDS 3.0 design. As a part of
