Connext Versions and Lifecycle

RTI offers two types of Connext releases:

Long-Term Support (LTS) Releases offer the highest level of production-ready stability for application deployment, including planned updates for security and stability improvements. RTI provides 7 years of standard support with options for Extended Maintenance and Support available. LTS releases generally include a roll up of new features from the previous Feature Releases.

Feature Releases provide new, cutting-edge features frequently. FRs are ideal for teams looking to explore and adopt new functionality early. RTI supports FRs for 7 months, by which time there will be a newer FR or LTS release.

For more details on the Connext release model, see here.
