    Is this not updated? I see emails today stating: 
    "Nebula has released a new firmware version for access points. New firmware will be available after two weeks. "

    What and when? No version numbers, no dates are mentioned. on this page nor in the email

    Hello @jeroenpotters
    Apologies for that, there was an issue in our mail system causing the format differ from what it's used to be. Normally it should consist of the timestamp of when upgrade will be performed according to your site settings. This should and will be fixed. 
    I've added the items in the post, sorry for being a little bit late :'( .
