1. What’s New in 7.6.0 EAR

RTI® Connext® 7.6.0 is the third feature release in the Jackson Hole series of releases culminating in Jackson Hole LTS in 2026. This release is marked as an early access release (EAR), which means that customers can use it in development, but not in production environments. This release enhances and stabilizes key features, in preparation for Jackson Hole LTS.

This document highlights changes since Connext 7.5.0 (unless otherwise noted). See the Connext Versions and Lifecycle page for more information on RTI’s software release model.

Note

For backward compatibility information between 7.6.0 and previous releases, see the Migration Guide on the RTI Community Portal.

Table 1.1 Key Features of *Connext* 7.6.0
	Remote Debugging Enhancements in Admin Console make collecting debug telemetry information more efficient and scalable.
	Strengthen Security while Reducing Operational Complexity by using short-lived permissions.
	Persistence Service Synchronization is more performant and production-ready.

For details about additional features and fixes in this release, see the release notes for a specific product:

1.1. Remotely Debug Systems Across Separate Networks with Admin Console

This release brings several enhancements to the remote debugging capabilities introduced in Connext 7.5.0:

Efficient Telemetry Data Handling: Telemetry required by Admin Console in remote mode is now sent to the Collector Service only if there is at least one active Admin Console session requesting it.
Scalable Debugging with Collector Chains: Admin Console now supports retrieving remote debugging telemetry through a chain of Collector Service instances. This enables debugging of larger, distributed systems spanning multiple networks. Edge Collector Service instances collect and forward telemetry to a central, cloud-based Collector Service, to which Admin Console connects for a unified view.

For details, see What’s New in 7.6.0 in the Admin Console Release Notes.

1.2. Short-Lived Permissions Increase System Security

Security Plugins now support short-lived permissions by enforcing a DomainParticipant’s permissions expiration time and subsequent DomainParticipant removal from the system. We also introduce a way to renew the permissions. With permissions expiration and renewal available, it is now possible to implement a short-lived permissions approach, where DomainParticipants must periodically revalidate their permissions within the system and continue their operations on an as-needed basis. This practice leads to increased security of a dynamic system and limits access to required participants only. For details, see Permissions Expiration in the RTI Security Plugins User’s Manual.

1.3. Persistence Service Synchronization Ready for Production

The new Persistence Service synchronization protocol, introduced in Connext 7.5.0, is now ready for production use.

While this synchronization protocol was already significantly more efficient than the protocol used before Connext 7.5.0, this release includes further enhancements to reduce bandwidth consumption and ensure faster convergence when changing data providers.

See the Persistence Service Release Notes.
