LMS 7.9.1 not downloading firmware

Since updating to 7.9.1 I see a lot of this type of warning in the server log.

[17-03-18 12:15:15.2647] Slim::Utils::Firmware::downloadAsyncError (581) Warning: Firmware: Failed to download http://update.slimdevices.com/update...1/fab4.version (404 Not Found), will try again in 640

Looks like the 7.9.1 folder has not been created yet.
