Mission Hills, CA, September 30, 2025 – UNICOM Global has announced it will provide day one support for the latest developments from IBM and 21CS. With IBM CICS TS 6.3 now available, IBM z/OS 3.2 due for release on September 30, and 21CS’s VSEn 6.4 release following on October 15, 2025, UNICOM Global is looking forward to supporting the latest in mainframe advancement. These releases bring critical new capabilities that align with UNICOM Global's focus on helping clients to modernize their mainframe environments. IBM CICS TS 6.3 and z/OS 3.2 The IBM CICS TS 6.3 is a significant step forward for developers and systems management. It includes a host of new features that make it easier to develop and manage CICS applications. For developers, CICS TS 6.3 now supports the latest language features, including Java 21, Jakarta 10 EE, MicroProfile 6, and Spring Boot 3. It also offers VS Code extensions and an AI agent that provides fast insights into a live CICS environment, saving valuable time. From a systems management perspective, the release introduces OpenTelemetry for distributed tracing and a streamlined, YAML-driven configuration tool, simplifying a traditionally complex process. Security is also a key theme, with enhanced zero-trust support and tools to help validate security definitions in continuous integration/continuous delivery (CI/CD) pipelines. The new z/OS 3.2 operating system is designed to be the foundation for hybrid cloud and AI workloads. It's engineered to work seamlessly with the latest hardware, including the new IBM z17, to provide unparalleled cyber resiliency and operational efficiency. The release integrates AI-infused capabilities throughout the stack, helping to automate tasks and provide actionable insights. With enhanced support for hybrid cloud application architectures, the z/OS 3.2 makes it easier than ever for organizations to integrate their mainframe into a broader, modern enterprise-wide data fabric. 21CS VSEn 6.4 The VSEn 6.4 introduces a new VSEn System License Key to offer more flexibility for testing and to streamline audits. It also enhances the VSEn REST API client to support batch workloads in addition to the existing online transaction processing (OLTP) capabilities. Furthermore, it provides a new way to shut down looping transactions without having to bring down the entire OLTP region, which is a major enhancement for high availability. "These new releases from IBM and the forthcoming VSEn 6.4 from 21CS.com are a clear testament to the mainframe's enduring value and its central role in the future of enterprise computing," said Larry Lawler, UNICOM Global's CTO, "By infusing AI and streamlining development and operations, IBM is making it simpler for our clients to leverage the mainframe's power for their most critical workloads. We're also excited about the VSEn 6.4 release, which demonstrates a continued commitment to the VSE platform by delivering valuable enhancements like the new VSEn System License Key and batch support for the REST API. At UNICOM Global, we are fully committed to ensuring our solutions support these innovations, so our customers can benefit from these exciting new capabilities for security, modernization, and business growth."
