The Workflow Full History module displays all the history for each version of an item in a single pop-up. The fields that have changed are included in the history. This expands upon the Sitecore Provided Workflow / History link that only displays history for the current version.
This module adds a Full History button to the Workflow group under the Review tab. The Full History button only appears for items that are participating in workflow.
Clicking the Full History button displays a pop-up with history for each version of the item.
There are 2 versions of the Workflow Full History module. One that supports Sitecore 6.6, 7.2, and 7.5, and another that supports Sitecore 8.1. Please note the correct release when downloading.
