When a page is created it is automatically endowed with the ability to have versions. A new version of a page is created anytime someone who has not edited the page before makes a change to the page. This can happen at any stage in the workflow process.
To see the different versions of a page, click the number next to the language flag (this number will vary depending on how many versions there are). In the example below, there are two versions. A page can have an unlimited number of versions.
To add or remove a Version, click on the Versions Tab.
Add a Version
Click Add on the version ribbon to add a version. It is a good idea to add a version if you are making significant changes, it may save you time in the future.
Remove a Version
1. Choose the version you wish to remove from the Versions menu.
2. Click Remove. Remove will delete the version you have currently selected. Make sure you have chosen the correct version before removing it!
