2.2. What’s New in 7.5.0 EAR

RTI® Connext® 7.5.0 is the second 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 document highlights changes since Connext 7.4.0. See the Connext Versions and Lifecycle page for more information on RTI’s software release model.

Note

For backward compatibility information between 7.5.0 and previous releases, see the Migration Guide on the RTI Community Portal.

Table 2.2 Key Features of Connext 7.5.0

	Remote Debugging with Admin Console (Experimental) enables you to remotely debug your systems that are running in separate networks.
	Productized Python RPC API enables Python developers to bridge the gap between Python-based clients or servers and the rest of the distributed system.
	AI Assistant in System Designer (Experimental) leverages the Connext Intelligence platfrom grounded in RTI’s vast knowledge base to help you design your system.
	Easier Security Management for Reducing Operational Complexity enforce identity revocation in the RTI Security Plugins without system restarts and improve authentication efficiency without affecting performance.
	Reduced Bandwidth Usage for Persistence Service Synchronization (Experimental) guarantees eventual consistency at the DDS instance level using enhanced synchronization mechanisms.
	Unbounded Types without Manual Configuration— Connext performs automatic memory allocation based on actual sample sizes.
	Achieve Faster Network Performance with out-of-the-box UDP socket buffer sizes that have been increased to reduce sample losses and improve throughput performance.

2.2.1. Remote Debugging with Admin Console (Experimental)

Admin Console can now participate in distributed systems, such as layered architectures and remotely deployed systems, allowing you to remotely debug your systems running in separate networks. For details, see What’s New in 7.5.0 in the Admin Console Release Notes.

Note

Remote Debugging was experimental when it was introduced in 7.5.0, but is no longer experimental starting in 7.6.0.

2.2.2. Productized Python RPC API

New Python support for RPC enables Python developers to bridge the gap between Python-based clients or servers and the rest of the distributed system. For details, see What’s New in 7.5.0 in the Connext Core Libraries Release Notes.

2.2.3. AI Assistant in System Designer (Experimental)

Create and modify your systems using natural language through an AI assistant in System Designer that leverages the Connext Intelligence platform grounded in RTI’s vast knowledge base. Ask questions, make changes, and get suggestions for improving your design. For details, see What’s New in 7.5.0 in the System Designer Release Notes.

2.2.4. Easier Security Management for Reducing Operational Complexity

Enhance flexibility and scalability by enforcing identity revocation without system restarts. The RTI Security Plugins implement key material regeneration and distribution independently of the remote DomainParticipant vendor. OCSP stapling simplifies certificate revocation checks, improving the efficiency of authentication processes without affecting performance. For details, see the RTI Security Plugins Release Notes.

2.2.5. Reduced Bandwidth Usage for Persistence Service Synchronization (Experimental)

Enhanced synchronization mechanisms improve data sharing across Persistence Service instances, minimizing bandwidth usage. In most cases, each Persistence Service will receive a DDS sample only once. The new synchronization protocol guarantees eventual consistency at the DDS instance level. For details, see the Persistence Service Release Notes.

Note

This enhanced synchronization was experimental when it was introduced in 7.5.0, but is no longer experimental starting in 7.6.0.

2.2.6. Unbounded Types without Manual Configuration

Manual configuration of buffer sizes is no longer necessary when working with unbounded data types; now we perform automatic memory allocation based on actual sample sizes. For details, see What’s New in 7.5.0 in the Connext Core Libraries Release Notes.

2.2.7. Achieve Faster Network Performance

The out-of-the-box UDP socket buffer sizes have been increased to reduce sample losses and improve throughput performance. For details, see What’s New in 7.5.0 in the Connext Core Libraries Release Notes.

2.2.8. Product Availability

The following products are not included in 7.5.0:

• RTI Ada Language Support
