Undefined index: release_channel - Piwik 2.14.3

Am I the first one or do I post this in the wrong group, this happened this morning (22/10) when I upgraded to the new version

WARNING: /home4//public_html/piwik/core/Plugin/ReleaseChannels.php(58): Notice - Undefined index: release_channel - Piwik 2.14.3 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)


if you get this error multiple times, then you can fix it by re-uploading your config/global.ini.php file

Only saw this error after the upgrade, never saw it again.
Piwik seems to work fine without problems so I think I can just ignore this error message, let see what will happen when I upgrade Piwik again.
