eXo IDE provides the versioning that enables you to realize the versions history of the file. With the versioning feature, you can:
A new version of the file is created each time after the file content has been saved by clicking Save. There is no versionF in the version history after the file had been created only.
To view the version history of the file which is being opened/selected, click 
at the right part of the toolbar;
Or, select View --> Version History... from the top menu.
The Version pane with content of the latest version are opened at the right column of the eXo IDE window.
The version name is displayed in the title of the Version pane.
Note
If the selected/opened file is not versioned yet, the View Version History function will be disabled.
The file version is opened in the read-only mode so you cannot edit it.
If any files are opened, the Version pane of the previously opened file will be closed automatically.
With eXo IDE, you can navigate to any older or newer versions of the opened file.
To view the older/newer version of the opened file, click 
or 
on the toolbar, or select View --> Older Version/Newer Version from the top menu. If there is no newer/older version, the View Newer Version/View Older Version command will be disabled respectively.
