As described in the previous section, AccuRev uses a diff operation to provide versions of a given element to Atlassian Crucible. In most cases, AccuRev determines which Diff Against operation to use based on the active view at the time you select the element for code review. For example, if you select an element from the Timeline Diff view, AccuRev diffs the versions at the start and end of the time period you specify. The following table summarizes the type of diff operation that AccuRev performs based on the current AccuRev view.
| AccuRev View | Type of Diff Performed | Description |
