The Changes tab of an issue record's edit form shows the change package of the issue record. You can run commands to see the details of the change package's changes, maintain its entries, and view the transaction and version history of its elements.
The Changes tab contains a table. Each row displays information about one change package entry. A given element can have at most one entry in a change package, but this entry can grow over time, as development work continues on the element.
The change package table includes these columns:
The head version and basis version are the endpoints of the change package entry. That is, the entry consists of all the versions between these two versions. The head version is included, but the basis version is not.
