Starting with RTI Connext® 6.1.1 LTS, RTI introduced a new software release model that adds both increased support and stability, as well as more agility to meet rapidly evolving customer and market needs. The bi-yearly Long-Term Support (LTS) release provides a production-ready platform with long-term support. With Connext 7.0, RTI is adding feature releases that will deliver new functionality every six months.

Feature Releases

Connext feature releases follow the same rigorous testing as our LTS releases, but also deliver new, cutting-edge features that enable new use cases and help transform markets. Developers may see new features evolve over time as we respond to developer feedback. New features transition to LTS releases once they have a stable definition and interface. Feature releases are supported for a six-month period, then we direct our attention to supporting subsequent feature or LTS releases.

LTS Releases

RTI understands that software is a mission-critical part of your application. This requires exceptionally qualified technical support in all areas of real-time and embedded systems to quickly troubleshoot and problem-solve.

To meet this need, RTI offers Long Term Support of seven years for select software versions of Connext. These select versions are identified as “LTS” in our product naming and referencing.

LTS Benefits

Offering LTS for select versions of our products gives our customers the peace of mind of high stability for application deployment and a predefined support window. LTS not only enables RTI to deliver exceptional support in the most effective and efficient manner as we and our customers grow, but also enhances the value of our entire product suite. Benefits include:

  • Planned updates for security and stability improvements
  • Highest level of software stability
  • Guaranteed support for 7 years
  • Extended support available after 7 years

Beginning with Connext 6.1.1, support for future non-LTS releases will end once an LTS version is released. For versions prior to 6.1.1, we will continue to offer support plans until a version’s end-of-life (EOL) – customers are notified of EOL two years in advance.

Connext 7.0 is an Early Access Release (EAR) type, providing customers with access to new or enhanced functionality that is still under development.
