Additions

• Added RtpsRelay -LogUtilizationChanges to RtpsRelay options (PR #4890)
• Added opendds_idl --append-typeobjects to opendds_idl options. It can be used to write XTypes Type Objects to a separate output file in addition to normal code generation. (PR #4898)
• Added RtpsRelay -SynchronousOutput option to RtpsRelay. (PR #4928)
• The TypeLookupService now has support for strongly connected components (recursive types). (PR #4940)

Platform Support and Dependencies

• ACE/TAO
  • Updated ACE 8/TAO 4 from 8.0.2 to 8.0.3.
• CMake
  • opendds_target_sources
    • Added support for using the same IDL files in different targets with different options. (PR #4962)
    • It will not automatically generate an export header when all IDL files are scoped PRIVATE unless opendds_target_sources(ALWAYS_GENERATE_LIB_EXPORT_HEADER) is set to TRUE. (PR #4962)
    • It will not export symbols in code generated from PRIVATE IDL files. (PR #4962)
    • Added support for the codegen target (CMake 3.31 or later) to build and run IDL compilers on targets with IDL. (PR #4962)
    • opendds_target_sources(USE_EXPORT) will now pass on its arguments to opendds_export_header(EXISTING). (PR #4964)
  • Fixes and improvements for opendds_export_header: (PR #4954)
    • opendds_export_header now allows specifying an existing export header and gives control over what names are used.
    • opendds_export_header and opendds_target_sources now set symbol visibility to hidden using CXX_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN on platforms where this applies.
    • Fixed Visual Studio failing because of inconsistent linkage of exported symbols when linking between a DLL and a static library.
  • Fixed issue with building iShapes demo with CMake. (PR #4884)
  • Improved C++ standard detection in CMake. (PR #4884)
  • Added opendds_bigobj to set /bigobj on targets that need it on Windows. (PR #4954)
  • When using CMake 4, fixed relative path issues when working within a symlinked directory, including a warning about CMP0177. (PR #4959)
  • Fixed issue with CMake being unable to find RapidJSON after installing OpenDDS. (PR #4973)
  • Fixed reconfigured cross-compiled builds trying to use TRUE as the path to host tools. (PR #4986)
  • Building OpenDDS with CMake
    • The Shapes Demo will now be built when Building OpenDDS Using CMake and OPENDDS_QT is set to TRUE. (PR #4884)
    • Improved support for using Xerces 3.3.0 when building OpenDDS using CMake. (PR #4926)
    • GoogleTest will no longer be installed if it was built as part of the OpenDDS tests. (PR #4973)
    • Added OPENDDS_INSTALL_RAPIDJSON to disable installing RapidJSON automatically. (PR #4973)
    • OPENDDS_ACE and OPENDDS_TAO can now be overrode after OpenDDS is installed. (PR #4973)
    • Fixed OPENDDS_COMPILE_WARNINGS=ERROR, which didn't work before. (PR #4986)
• Updated GoogleTest to be compatible with CMake 4. (PR #4959)
• OpenDDS's use of std::optional or an emulation is determined by the configuration file (PR #4976)
  • See OPENDDS_CONFIG_STD_OPTIONAL in dds/OpenDDSConfig.h
  • Default is to use std::optional on compilers that support it
  • See configure script's --no-std-optional or CMake's OPENDDS_STD_OPTIONAL
• New configure script option: --[no-]static-runtime (PR #4977, PR #4983)

Fixes

• Added RTPS_HARVEST_THREAD_STATUS property to select the participant that harvests thread status. (PR #4887)
  • This addresses erroneous results from multiple participants harvesting thread status.
  • See OpenDDSInternalThread Topic for usage.
• Signal the thread monitor in RtpsRelay listeners to avoid thread monitor timeouts. (PR #4900)
• Introduced a time separation when processed expired discovered participants with RtpsDiscovery. (PR #4908)
  • See [rtps_discovery] MinimumCleanupSeparation.
