FEH slideshow command --cycle-once unrecognised option in Ubuntu 20.04

[Paul Hurford]

After upgrading to Ubuntu 20.04 I ran the FEH (version 3.3-1) slideshow with the same criteria I always have, which is:

$ feh -rz --fullscreen --auto-zoom --cycle-once /home/paul/Pictures/Slideshows/Art/Seen

It worked perfectly as normal, however after scrolling through the slideshow once it began to repeat. When I exited I found the following entry in the terminal:

feh: unrecognized option '--cycle-once'

feh 3.0 removed support for --cycle-once, please use --on-last-slide=quit instead. It has the same effect.
