If your organization uses only one release of Interactive Reporting Studio, you can skip this warning. Interactive Reporting Studio is backwards compatible; thus a later release opens Interactive Reporting documents built with an earlier release. However, if an earlier release opens an Interactive Reporting document created with a later release, the earlier release discards information about features that it does not recognize. If the Interactive Reporting document is saved, the unrecognized information is lost permanently. Therefore, in a mixed-release environment, use only features that are supported by the earliest release. For example, if your organization uses Release 6 and Release 8, do not use UserValues (introduced in Release 8). If your organization uses Releases earlier than 8.2 and Release 8.2 or later, do not use JPEG or GIF images, which are not recognized and are discarded by Releases 8.1 or earlier.
