Affected version(s): > 7.10.5
With 7.10.5 a new greeting dialog was introduced to show the new main features of that version. It is shown for all users once but you want to disable it.
It is possible to disable the dialog for all users or finer grained with the config cascade. The used option is io.ox/core//whatsNew/autoStart.
To disable it for all users put the option into a configuration file, for example /opt/open-xchange/etc/settings/appsuite.properties
Note: the setting is case sensitive.
A reloadconfiguration or a restart of the open-xchange service activates the setting.
