Madrid, June 2020

With the release of version 2.0, eProsima announces the compliance of Fast RTPS with the OMG DDS 1.4 standard and therefore the symbolic change of name to Fast DDS.

In addition to this achievement, Fast DDS 2.0 offers improved CPU and memory usages besides other improvements and new features. 


eProsima Fast RTPS is a high performance publish subscribe framework to share data in distributed systems using a decoupled model based on Publishers, Subscribers and Data Topics. The dds middleware implements many DDS specifications like DDS Security, DDS-XTypes, RPC over DDS, DDS TCP PSM and Modern C DDS Mapping but some core DDS APIs were not yet fully compliant with the standard.
With the completion of the compliance with the OMG DDS 1.4 standard, eProsima also changed the name to Fast DDS 2.0!

Important changes for the version 2.0 are:

API breaks:

  • eClock API, which was deprecated on v1.9.1, has been removed
  • eprosima::fastrtps::rtps::RTPSDomain::createParticipant methods now have an additional first argument domain_id
  • Data member domainId has been removed from eprosima::fastrtps::rtps::RTPSParticipantAttributes and added to eprosima::fastrtps::ParticipantAttributes

Deprecation announcement:

  • All classes inside the namespace eprosima::fastrtps should be considered deprecated. Equivalent functionality is offered through namespace eprosima::fastdds
  • Namespaces beneath eprosima::fastrtps are not included in this deprecation, i.e. eprosima::fastrtps::rtps can still be used

New features:


But there is more:

The new version also includes other features, bug fixing and performance improvements.

For a complete list of improvements and bug fixes please read the Fast DDS release notes
