These are Zenpacks that are as-of-yet untested on Zenoss 3.*, or they are only available for previous versions of Zenoss, or have been superseeded by better options. Of course, if you want to update a ZenPack for the current version, anyone can move them from this list back into the main ZenPacks list.
