Gpg4win's Kleopatra does not find 3.1.16, though it is available as update.
* Start Kleopatra
* Select Help -> Check for updates
Observation: After the dialog "Searching for updates..." it is running for a while,
you'll get a dialog saying:
"No update found in the available version database."
But, on the command line it can be seen that a version database is available.
Thus the expected behaviour is to see that an update is there.
