Wolfgang,
CTG is still a strategic offering for integration with CICS TS, and enhancements continue to be made. CTG V10.1.0 was released in August 2024. One of the key enhancements delivered is HA capability for IPIC connections between CTG z/OS and CICS TS. In September 2024, the CTG product team gave an excellent overview of explaining CTG's role as a strategic integration solution as well as a number of new features.
