There are two new UIs:
Jopr and
Embedded Jopr.
Jopr is the open source version of
JBoss ON. We mention id but do not cover it (there is already extensive documentation).
We do cover Embedded Jopr, which is the new admin console, in appendix B.
We do not cover microcontainer programming. But we do cover quite a bit of configuration that is now POJO-based.
