The new version of ZViewer is available on the Zmodo Website.
Auto-Updates have been suspended, currently updates require user initialization. It has not yet been determined if this change is temporary or permanent.
We are working with the development and design teams to find a solution to only allowing secure devices to have access to the server that does not involve an auto-update function for the firmware.
Once that solution has been found and implemented, I will post an update here.
Here is the download link for the newer version of the Zviewer software
