There are four new files on the google drive. One is just the latest version of rnafold.pl. The other three are output files for gs1 (gene synthesizer level 1) with wide medium and narrow focus. Note the difference in file size. The run times were similar (36 to 41 min.). I think this is because, although the narrower focus produces fewer results, it does extra crunching to weed out the less likely ones.
