The team in charge of APEX at Oracle has just released the early adopter version 4.2. Of the main striking features is the package applications option. Préviously, those applications were available on Oracle OTN and then were later removed.
Now, you can access them from the application dashboard as shown in the screenshot below.
The list of all the enhancements to the new version can be found here: http://apex.oracle.com/pls/apex/f?p=38997:1:9960399329701::::P1_FEATURE:Application%20Builder%20Enhancements
