When I ran "update now" from 8.7 beta 4 to 8.7 RC1, the message in Logos was "installing update" indefinitely. When I shut down the program, I got a dialog box with "a new version is available to install" (or something similar). I suspect that dialog box was hidden all along. This might be a quirk of updating the beta to the release candidate, but it would likely be confusing to a user if it happens during the normal automatic update process.
