It is possible to set precedence between pages.
You need two pages (Article, Category, TOC only) to set the precedence and use the Wiki Precedece option
For example following this Wiki content, you can set precedence between version 5.0 and 6.0;
Precedence is used to define the "order" between branches. For this case the order is version 5.0 and then version 6.0. When the user is logged and a specific branch is selected; during the navigation GXwiki will check and display those pages closer to the selected branch.
If you want to see this feature in action; compare these links and the options available: Other versions or Previous versions
Each page can only have a single Precedence tag.
The Precedes tag applies to Articles, Categories and TOCs only.
