I want to pin CSV.jl to version 0.3.1 because version 0.4.1 cannot read my file.
When I pin it, I cannot update it anymore, however, installing a new package makes it change the version.
```julia

No, it is a bug, but it has been fixed, and the fix will be in Julia v1.0.1 that will be released in a week or so.

Could you share the csv file that is having trouble? Or open an issue w/ CSV.jl? The update tried very hard to not break anything.
