Users are shown how a web page has been modified from a previous version. Information related to differences between the current version of the web page and a previous version of the web page is provided in response to user-initiated activity within a predefined region of the current version of the web page. In some embodiments, when a user attempts to activate a feature of the web page at a location associated with a former location of the feature in a previous version of the page, the feature is activated, but update information related to the differences between the previous and current versions of the web page is displayed over at least a portion of the information generated by activation of the feature. In some embodiments, the user is required to perform a specific action in order to clear the display of the update information.
