This can happen when i upload a new version but decide that it's too minor an update to bother updating the version number that the updater sees.
When this happens -- people who downloaded before this "silent" update do not get prompted to download and install the new update, and to them the program looks up to date. And people who grab the new version wil see that they have a newer version than the updater knows about (if i updated the minor version #).
I've gone ahead and updated farr to new version so everyone should see it now.
