When downloading the macOS binary of Duplicati 2.0.2.1 from the Duplicati Download page, the app displays a version tag of 2.0.2 instead. Shouldn’t the version tag be set to 2.0.2.1?
I can confirm that on MacOS Sierra 10.12.6 the web GUI “About” pages says “2.0.2.1_beta_2017-08-01” but the “Get info” on the installed application says “2.0.2”.
In looking at Google Chrome both the application “Get info” and the browser “Help -> About Google Chrome” menu show the long “61.0.3163.100” so apparently it’s not just an OS limitation.
