    1. Z Code Optimization Advice can now analyze programs compiled
    with Enterprise COBOL 4.
    
    2. Z Code Optimization Advice can now analyze programs
    executing in a zPDT or zD&T environment. As these environments
    are not native z hardware, performance measurements and
    problem priority may be inaccurate. To obtain accurate
    measurements for how a program will perform in production
    environments, profiling must be done on the same z hardware
    version used in the production environment.
    

Problem conclusion
