Additions

• Added an XCDR2 value writer that can be used to serialize static and dynamic samples to XCDR2 encoding format. (PR #4421)
• Added utility to flatten the index to a multi-dimensional array represented by dynamic data. (PR #4421)
• A new header, dds/OpenDDSConfig.h is generated by configure or CMake. (PR #4482, PR #4498)
  • Users manually configuring a build will need to create this file, which may be empty, or add #define OPENDDS_IGNORE_OPENDDSCONFIG_H_FILE to their ace/config.h file.
  • See dds/OpenDDSConfig.h.in for details.
• ConfigStore
  • Converted the transport and discovery loading and domain section to use ConfigStore. (PR #4488, PR #4475, PR #4469, PR #4454)
  • OpenDDS can now be configured with environment variables. (PR #4491)
    • See Configuration with Environment Variables for details.
  • OpenDDS now supports multiple config files. (PR #4505)
    • See Configuration Approach for details.
  • The ConfigStore is available in Java. (PR #4515)
• The @value(x) annotation is now supported on IDL enumerators when using the IDL-to-C++11 mapping. (PR #4519)
  • See @value(v) for details.
• The IDL for the Shapes example was updated for interoperability. (PR #4528)
• Added [rtps_discovery] SpdpUserTag. (PR #4533)
• The data type for the OpenDDS-specific Built-in ParticipantLocation Topic now includes the lease duration. (PR #4545)
  • See OpenDDSParticipantLocation Topic for details.
• Allow compile-time configuration of CLOCK_BOOTTIME as the clock used for timers (PR #4568)
  • If the platform supports it, this can be done using --boottime when building with the configure script or OPENDDS_BOOTTIME_TIMERS when building with CMake.

Platform Support and Dependencies

• Building with CMake
  • Fixed building with CMake and Apple Clang on macOS without setting -DCMAKE_CXX_STANDARD=14 or using ACE 6. (PR #4481, PR #4487)
  • Added support for C++03 and some support for building ACE/TAO with the same compiler and C++ standard as OpenDDS. (PR #4481, PR #4487)
  • Fixed building release builds on Windows at the same time as ACE/TAO (PR #4535)
  • Fixed ACE/TAO build not getting Xerces path when using OPENDDS_XERCES3. (PR #4572)

Fixes

• The ValueReader and ValueWriter interfaces now use ACE_CDR::Fixed as the type of IDL fixed values (PR #4466)
• CMake Config Package
  • Made opendds_target_sources(INCLUDE_BASE) work correctly in more cases, specifically involving generating an export header. (PR #4489)
    • Added opendds_target_sources(EXPORT_HEADER_DIR) and opendds_export_header(DIR) as part of these changes.
• Fixed bug so ConfigStore entries generated by SEDP are cleaned up. (PR #4540, PR #4485)
• Fixed bug where various RtpsDiscoveryConfig setters didn't set. (PR #4540, PR #4485)
• Fixed bug where vread for unions used uninitialized memory. (PR #4544)
• Fixed bug where an RTPS Reader gets stuck when heartbeat advances. (PR #4548)
• XCDR2 KeyOnly serialization of union that has no key now has a delimiter for appendable and mutable extensibility. (PR #4554)

Documentation

• Run-time Configuration (PR #4464, PR #4570, PR #4467, PR #4588)
  • Restructured configuration properties so they can be linked to directly.
    Also reviewed each property description to correct or add missing context as needed.
• Introduction to OpenDDS (PR #4467)
  • Added Plugins to explain generally how discovery, transports, and security libraries must be initialized when statically linking these libraries.
  • Added summaries of important information needed to use the discovery and transport libraries.
• Quality of Service (PR #4520)
  • Added Property QoS, Data Representation QoS, and Type Consistency Enforcement QoS.
  • Every policy now has a box that says if it's mutable, if it affects writer-reader association, and a link to the spec definition.
    Also removed large default value tables and put the default values in these boxes.
  • Added links to the QoS policies.
• Added definitions for instance, unregister, and dispose to the glossary. (PR #4520)
• DDS Security
  • Added summary of important information needed to use the security library. (PR #4467)
  • Moved Fnmatch Expressions into an "annex" file so it can be common between security and partitions QoS. (PR #4520)
• ConfigStore
  • Add configuration capabilities to DevGuide. (PR #4556)
