mihha The support ticket is open since yesterday. Therefore version 8.6.1 has been released. No individual check at my installation was needed. Therefore a public post here would have been sufficient but on your earlier request I opened a support ticket. You could also just have worked with an internal ticket.
I also posted here to warn other users. You did not put a warning out that version 8.6.0 had a severe bug. Neither you stopped the download.
You should understand that it is VERY annoying when a system suddently sends out birthday emails to ALL subscribers.
