We are excited to announce the availability of RTI Connext® 7.3 LTS, the newest release under the long-term support (LTS) model designed to empower you to create the intelligent distributed applications of the future.

New Capabilities in Connext 7.3 LTS:

  • Connext Observability Framework (experimental): Monitor your operational Connext applications and CI/CD pipeline using a Grafana® and Prometheus® stack.

  • Pre-Shared Keys (PSKs): Enhance system security against cyber attacks, including resource-constrained devices that have limitations in terms of RAM or CPU or high performance demands.

  • New Cryptographic Algorithms: Ensure top-secret level data protection and use trusted platform modules (TPMs) to safeguard cryptographic keys in hardware.

  • Participant Partitions: Architect and dynamically create subsystems for seamless interaction while maintaining independence from other subsystem chatter.

  • Simple Participant Discovery Protocol (SPDP) 2.0: Streamline participant discovery and liveliness by minimizing redundant information exchange.

  • New Python Support: Expedite mission-critical systems development and testing in a familiar programming language.

  • Graphical Data Publishing in Admin Console: Easily test and validate your applications.
