New API methods have been added to clone and modify custom dashboards. On top of that, scheduled reports (for sending automatic email reports based on a dashboard) can now be added using the API. This combination allows you to take a custom dashboard you’ve prepared, and use that as a master template to generate dashboards and scheduled reports for specific teams or customers who wish to receive email reports.
Additionally, there are new API methods for managing Public Status Pages. It’s probably not very efficient for you to use the API to manage one or two public status pages, but if you’re interested in using the protected status page function (read more here) to publish status information to separate teams or interested parties outside your organization, then it might be useful to automate that using the API.
