Could I suggest you include these instructions for manual download and installation on DSM 7 for the current and future versions on the main Updates page (with suitable caveats/warnings). The Synology approval process is clear far too slow (it can take months for an update to appear, and even then it tends to lag behind the current version), so I suspect most of us using Nakivo on synology are now updating manually (and how to do so is becoming a FAQ).
