On this tab, you can see all workflow versions of the selected document. You can perform the following actions with the versions:
|•||View - displays an overview of the document's content with the possibility of side-by-side comparison of versions|
|•||Rollback - rolls back any changes made since the particular version of the document|
|•||Delete - deletes the old version|
You can also use the Destroy history button to clear the history and restart version numbering. The Destroy permission for this document must be granted to the user.
The history also shows when the particular version has been published and when it was replaced with a new version.
The length of the version history can be configured in Site Manager -> Settings -> Content management -> Version history length.
Automatic version numbering
Kentico CMS supports automatic version numbering:
|•||If you use workflow without content locking, automatic version numbering is used by default.|
|•||If you use content locking, this option is optional and can be configured in Site Manager -> Settings -> Content management -> Use automatic version numbering.|
The automatic version numbering works like in the following example:
|•||0.1 - first version of the document when it's created|
|•||0.2 - second modification of the document|
|•||1.0 - first published version of the document|
|•||1.1 - first modification of the published document|
|•||2.0 - second published version of the document|
Side-by-side comparison of versions
If you click the View () icon next to a version, the Document version pop-up dialog appears. It allows you to view a side-by-side comparison with other versions of the document.
You only need to select the appropriate version in the Compare to drop-down list. Content of the two versions will be displayed side-by-side with the changes highlighted in red font. You can roll back the document to a particular displayed version by clicking the Rollback () icon in the top-right column of the version's column.
