When the new version is out, i know there should be a notification on ispconfig panel about the new version, and on 2 other vps i manage i get the notification, but on one i don't get the notification that there is a new version out.
The notification is checked on login, maybe you did not re-login for quite some time? Or the server can't reach ispconfig.org website to download the version info file.
Maybe i figured out why is not showing the new version. On this server i have ISPConfig 3.2dev20210520 installed, could this be the reason ?
This is a outdated and development version. Update to the latest version with Code: ispconfig_update.sh
