It is displayed here the list of Packages by Category for a combination of Release and Platform chosen by thye user. WARNING: In case a different Release is chosen from the drop down menu list, an arbitrary platform (first in the list) will be chosen.

The list of Platforms is dependent on the Release chosen.
