The standard history tab of work items in Azure DevOps shows only the old and new values of each field, without highlighting the actual changes within it. This makes spotting the difference very hard for fields that usually contain a lot of text; most prominently, the standard "Description" and "Repro Steps" fields and the comments. This extension adds a new tab to work items that shows the full history of every field, while computing an appropriate diff for each one.
