Using the View history option in the Options panel, you can view previously saved versions of the page and compare them.
- Navigate to the desired wiki page.
- Click More.
- Click History. The list of revisions appears.
- To compare two versions:
- Select the check box for each version you want to compare. (You can only compare two versions of the page.)
- Click Compare versions. The comparison page appears.
The comparison window appears. Deletions that happened in the previous version (if any) are shown in red and struck through. Additions that happened in the most recent revision are shown in green.
The top of the window shows you which versions you are comparing, and links to those versions as well as the current version.
