Additions

• Complete interfaces for dealing with DynamicData and DynamicTypes. (PR #4320, PR #4339)
• It is now possible to specify the validity for individual publish/subscribe actions in DDS Security Permission documents. This is an OpenDDS extension. (PR #4344)
• Building with CMake
  • Added new options for how to get ACE/TAO. (PR #4346)
• CMake Config Package
  • Added OPENDDS_ACE_VERSION and OPENDDS_TAO_VERSION. (PR #4346)
• Add a warning that @optional is not supported. (PR #4355)
• Convert discovery configurations (repository, static discovery, rtps_discovery including templates) to key-value store. (PR #4360, PR #4361, PR #4426, PR #4411, PR #4276, PR #4347)
• Convert ICE configuration to key-value store. (PR #4360, PR #4361, PR #4426, PR #4411, PR #4276, PR #4347)
• Change transport_template and rtps_discovery template processing to not generate new keys. (PR #4360, PR #4361, PR #4426, PR #4411, PR #4276, PR #4347)

Platform Support and Dependencies

• Improved support for configure script detection of clang on Linux (PR #4449)
• When using Visual C++, OpenDDS can now be configured using --std=c++NN (NN = 17 or 20). (PR #4452)

Fixes

• Updated the read and write semantics of DynamicData for union, expandable collections (sequence and string), and optional member of an aggregated type. (PR #4278)
• Fixed memory leak where instances were not cleaned up with exlusive ownership. (PR #4343)
• Removed the special handling for sequence members with length code of 5,6, or 7. (PR #4376)
• Reading data from a dynamic data object for a primitive type now must use MEMBER_ID_INVALID id. (PR #4376)
• create_datawriter and create_datareader check if the topic belongs to the same participant as the publisher/subscriber. (PR #4398)
• Fixed uninitialized durability_service in Topic QoS when using QoS-XML. (PR #4424)
• Fixed a bug where compiling IDL with -Lc++11 -Gequality produced code outside of a namespace that didn't compile. (PR #4450)
• SedpLocalAddress now defaults to DCPSDefaultAddress to behave like SpdpLocalAddress and local_address. (PR #4451)

Notes

• TheParticipantFactory* will now return a null pointer when DCPSConfigFile doesn't exist. (PR #4372)
