For those of you who want to switch from 1.6.0 alpha 1 to 1.6.0 beta 1, you will notice that there is not update check working and thus no automatic update process. You have to do that by hand.
I just installed the 1.6.0 beta 1 āoverā the alpha 1, confirmed that the folder i want to install already exists and then let the installer do its job.
Didnāt want to mount all my vaults again and assumed this will be the less risk way to loose this configuration instead of uninstalling the alpha and risk to delete the configuration as well. And I was right. All vaults there. So far no problems.
New version shown in āaboutā tab is āSNAPSHOT (msi-3205)ā.
(Seems that the Name āBeta 1ā didnāt make it in the āaboutā tab of this beta 
)
Many thanks Michael, 1.6.0 B1 working perfect on my Linux Manjaro xfce desktop.
