The Project History view is a window that displays the history of a project, including the checkpoint number and description, author, date, labels, and promotion state of the project.

By default, the project history view displays two panels: a panel showing the path of development, and a panel showing details for a selected checkpoint. In order for information to display in the details panel, you must select a checkpoint in the GUI or click a revision number in the Revision column in the Web interface.

In the GUI, you can use a project history filter to display any checkpoints of the current project that meet specified selection criteria. You can change the filter by selecting View > Change Filter.

If you have configured the Project History view to be dynamic, it is automatically updated to reflect changes in the Projects view and the Project view.

In the GUI, you can toggle between a graphical view and a list view by clicking View > Graphical or View > List.

The information in the graphical view shows the path of development from checkpoint to checkpoint, including branches and merge lines. You can change the information that displays for each checkpoint by selecting View > Show beside each node. If summary information is not displayed in the view, it displays in a tooltip when you place your mouse pointer on a specific checkpoint.

In the graphical view, some revision IDs may be truncated to improve readability and visual layout. To show full revision IDs, select View > Show Full Revision IDs.

The information in the list view is displayed in columns. If the Associated Items column is displayed, and there are multiple PTC RV&S item associated with the checkpoint, clicking on a cell in this column changes it to a drop down list.

The details panel in the graphical or list view displays additional details for a selected checkpoint. You can turn the display of this panel on or off using the View > Show Details option. The following information can display in the project history details.
