ITM 6.23 Fix pack 2 is now available. This is a cumulative fix pack for ITM 6.2.3, and supersedes ITM 6.23 Fix pack 1. The fix pack contains over 90 APAR fixes as well as a set of new features.
One thing to keep in mind is the new OMEGAMON releases (OMEGAMON z/OS, CICS, IMS, Storage. Mainframe Networks V5.1, OMEGAMON DB2 V5.11, and OMEGAMON Messaging V7.1) all will require ITM 6.23 support for the enhanced 3270 user interface. I still see quite a few customers running ITM 6.22, so if you want to move to the new OMEGAMONs, now is the time to start upgrading your ITM infrastructure.
