just out of curiousity since I saw this line at another package as well: whats the difference/benefit over?

julia 0.7-

[timholy]

I haven't tested, but I was assuming (based on past experience, I think) that 0.7- would mean 0.7.0 and upward. Since that hasn't been released yet there would be a version error.

I also asked on slack after this. The answer i got from the helpdesk channel was that while technically julia 0.7- does include all pre-releases, it does not work well with Femtocleaner.
