Notification about an "upgrade" to ownCloud 9.1.1 in Nextcloud 10 stable

Hi Lukas,
thank you for the hint and your solution.
A little bit strange in this area is the following detail:

within the config.php the version string is:

‘version’ => ‘9.1.0.16’,

and in the version.php the strings are:

$OC_Version = array(9,1,0,16);
$OC_VersionString = ‘10.0’;
$OC_Edition = ‘’;
$OC_Channel = ‘stable’;
$OC_VersionCanBeUpgradedFrom = array(9,0);
$OC_Build = ‘2016-08-25T04:01:11+00:00 678fce3c18c6fbed60076764ae98171eae617c05’;

This looks a little bit strange for me.

PS: Please excuse, to use this thread, but it is corresponding directly to the issue from above.
Regards, Axel
