      Hi John, Let me socialize this internally, and see if anyone else has had this issue.

    Is there a better way of tracking for updates/patches than looking at this blog?. You have implemented this command /opt/zimbra/libexec/zmcheckversion in Zimbra. But it will nog check on Patches.

    If not, please update command /opt/zimbra/libexec/zmcheckversion to check for Patches.

    Hi Dennis,
    Right now the zmcheckversion only checks for major/minor versions, not patches.

    We are working to improve this for Zimbra 9.0.

    Thank you for your feedback.
