Auto-update now works.
Earlier builds checked for updates against a private repository they had no credentials for, so the check failed silently and no installed copy could ever update itself. Builds are now published here, where the app can reach them.
If you are on 0.1.17 or earlier you need to install this one manually — the old build cannot update itself to the build that fixes updating. After this, updates are automatic.
