Connext Releases

RTI-Placeholder

RTI's software release model offers support and stability, as well as 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. Between LTS versions, RTI publishes feature releases of Connext to deliver new functionality every six months.

Connext feature releases follow the same rigorous testing as our LTS releases, but also deliver new, cutting-edge features and capabilities that enable new use cases and help transform markets. New features and capabilities transition to LTS releases once they have a stable definition and interface. LTS releases are supported for seven years (with an option for extended maintenance an support). Feature releases are supported for seven months and are not subject to maintenance, after which we focus primarily on supporting subsequent feature and LTS releases.

Maintenance Releases and Security Updates

For each Connext Long Term Support (LTS) release, RTI maintains the software packages and provides security updates, for a period of twelve years. The lifecycle consists of (1) the standard seven-year maintenance period, during which maintenance updates are available with a  Connext Developer Subscription, and (2) five years of Extended Maintenance (EM).

Connext platform support is dependent on availability and maintenance status determined by the platform vendor. To request new platforms for existing or future maintenance releases, please contact your account team. At RTI, we provide cumulative patches rather than custom ones that only address specific issues reported by customers. Additionally, our patches are designed to be applied on top of the latest Maintenance Release to ensure the most up-to-date and comprehensive fixes are included. 

RTI proactively provides security updates to its customers based on its vulnerability policy, and informs them through a dedicated channel to mitigate any risk exposure. To join or be removed from the Security Notice Program, email security@rti.com.

Customers of RTI can ask for an extended maintenance commitment beyond the extended Maintenance package. Contact us for more information.
