Supporting Multiple Editions

When creating a managed package, it is important to decide which editions the package will support, or what additional features customers will need to purchase to use the package. For example, some Professional Edition capabilities can be purchased individually for a Group Edition org.

Another approach to supporting multiple editions is to  use extension packages with additional capabilities for each subsequent edition. However, extension packages complicate package development and testing, and using extension packages is not a decision to be made lightly.
