Having used Oracle APEX since its first appearance on the Early Adopter Platform I finally got my hands on the real thing and installed in on my test-system.
This Post tries to give you a summary of the big changes in Oracle APEX 4.2 (compared to 4.1.1) from a datamodel/view/API Point of view.
If you are coming from APEX 4.0 (or older) read the Posts about the differences in Oracle APEX 4.1 and the Patchset 4.1.1 at first.
