We are thrilled to announce the official release of RTI Connext® Professional 7.7 Long-Term Support (LTS).
Connext Professional 7.7 is the production-ready culmination of our previous feature releases (7.4, 7.5 and 7.6). Designed to de-risk long-term programs, it provides the stability and high-assurance foundation you need to ship smarter products faster. More than a messaging platform, it powers real-time data streaming for physical AI, delivering fast and reliable coordination across critical systems. Unlike cloud-native solutions, Connext runs at the edge, where speed and precision matter most, shifting from complex integrations to a data-centric approach.

How Connext Professional 7.7 LTS Accelerates Your Production:
This LTS release incorporates all the major innovations previewed in our previous feature releases, now fully hardened for production environments:
Scale with performance: Reduce startup delays with optimized endpoint Discovery and bring large-scale architectures online faster while dramatically reducing network overhead. A 15-40% reduction in Connext memory footprint now allows you to run efficient distributed systems on constrained hardware. Additionally, our Persistence Service now provides the bandwidth efficiency and resilience required for cloud-ready, large-scale deployments.
Code in Your Preferred Language: Plug in Google Protocol Buffers (.proto) schemas directly to eliminate custom translation layers. You can also leverage our production-ready C++ and Python RPC APIs or our new Rust Connector to bridge modern applications instantly.
Deploy with Ease: Spend less time on setup. Use native Debian packages and Docker images for instant deployment, or simplify installation with our native Linux ARM installer. Our default-On Observability framework now empowers you to monitor and debug geographically distributed systems in real-time.
Maintain Mission-Critical Reliability: Real-time certificate validation (through OCSP) ensures updates to security posture without downtime. Flexible isolation reduces operational complexity in order to scale cleanly, preventing cascading failures. Significant improvements to Origin Authentication enable insider attack protection with minimal performance impact.
AI-Assisted Productivity: Connext AI acts as an autonomous agent to accelerate troubleshooting. Stop switching between your coding environment and documentation; by leveraging our new MCP server (Get started here), your AI agent queries Connext AI inline to deliver accurate, RTI-specific answers directly within your workflow.
