Additions

• The Observer interface now has support for dispose and unregister. (PR #4137)

• OpenDDS now stores configuration information in a key-value store. (PR #4138, PR #4134, PR #4151)

  • Configuration values can be set via API, config file, or command line.

    • Currently applies to the common section and common transport configuration.

• Added encode_to_string, encode_to_bytes, decode_from_string, and decode_from_bytes to TypeSupport. (PR #4144, PR #4122, PR #4133, PR #4135)

  • These methods convert samples to and from other formats.
  • Currently only OpenDDS::DCPS::JSON_DATA_REPRESENTATION is supported.

• Add -Gequality option to opendds_idl to generate == and != for structs and unions. (PR #4154)

  • The members of the struct or union must have a type that could appear in a DDS topic and be supported by opendds_idl.
  • The motivation for this change was to make the generated code more useful as many users go on to define these operators.

• CMake Config Package

  • Added executable targets. (PR #4160)

  • OPENDDS_CMAKE_VERBOSE output has been expanded, but now accepts a list of categories to control how much is logged. (PR #4160)

  • Added opendds_export_header to generate an export header. (PR #4160)

  • opendds_target_sources:

    • Added opendds_target_sources(GENERATE_SERVER_SKELETONS) to allow tao_idl to generate code for CORBA servers. (PR #4140)
    • Added opendds_target_sources(AUTO_LINK) as a fine-grained version of OPENDDS_AUTO_LINK_DCPS. (PR #4140)
    • Added opendds_target_sources(SKIP_TAO_IDL) to disable tao_idl. (PR #4140)
    • Added opendds_target_sources(SKIP_OPENDDS_IDL) to disable opendds_idl. (PR #4140)
    • Added opendds_target_sources(USE_EXPORT) to allow overriding the generated export header with an existing one. (PR #4160)

  • Libraries and features can be passed to find_package(OpenDDS COMPONENTS) to change what is required. (PR #4160, PR #4140)

    • See Components for details.

Security

• Fixed null pointer exception caused by RTPS Parameters with incorrect zero size. (PR #4197)

Fixes

• CMake Config Package

  • Made linking dependencies and macro definitions closer match using MPC with OpenDDS and TAO. (PR #4140)
  • Fixed issues with passing OPENDDS_IDL_OPTIONS -SI to opendds_target_sources. (PR #4140)

• Fixed issue deserializing bounded sequences with JSON (PR #4150)

  • The deserialization will fail if the JSON input contains more elements than the bounded sequence can hold.

• Updated the RtpsRelay's tracking of client IP addresses so they are removed when no longer used. (PR #4202)

  • The RtpsRelay configuration option -MaxAddrSetSize was renamed to -MaxIpsPerClient

Documentation

• Moved various markdown files into the Sphinx documentation so that they are now included along with the Developer's Guide: (PR #4139)

  • INSTALL.md is now Building and Installing.
  • docs/dependencies.md is now Dependencies.
  • docs/cmake.md is now Using OpenDDS in a CMake Project.
  • docs/android.md is now Android.
  • docs/ios.md is now iOS.

• Restructured how the documentation is presented to cleanly separate the Developer's Guide and internal documentation. (PR #4139)

• Added a proper main page. (PR #4139)

• Added Glossary. (PR #4139)

• In addition to NEWS.md, started adding release notes to Release Notes. (PR #4125)

Notes

• CMake Config Package

  • OPENDDS_TARGET_SOURCES is now called opendds_target_sources. (PR #4140)

    • CMake macros and functions names are case insensitive, so this should have no effect on CMake code.
