One big change is not actually a fall-out of z13(s) but of microcode that you might have installed already but now require. That is removal of Java from system console apps. You no longer need any Java at all, which implies that -version is now irrelevant. Hooray.
Another change is in the hardware memory segment size. When we upgraded from z196 to z13s, the segment size increased so that some previously running LPARs no longer met the boundary requirement. We had to increase the memory size to pass muster at definition time. This is a small adjustment of no real consequence, but be aware that any segment memory not allocated in the Image profile will be forever wasted. Not usable by any other LPAR on the box. So when updating the Image profile, you might as well round it up the next segment boundary. This change is not new for z13(s), but we overlooked it on our z12 upgrades. . .
