This is Deneb version 1.7.2, as submitted to AppSource for certification. Certification is currently pending, and the AppSource version will be attached as soon as it has passed successfully.
Please take a look at the change log for what's new in this release.
Note that the AppSource version has features disabled that would prevent it from being certified. Currently, this is just for fetching remote data (such as images or external datasets) via URLs.
If you need these features, you can download a standalone version from the assets below that is not tied to AppSource and will allow you to fetch remote data, providing that an external endpoint enables cross-domain requests from sandboxed iframes (which is how custom visuals are displayed in a report). Because this is not tied to AppSource, it is uncertified.
