Why specify compat in this manner? https://github.com/yolhan83/BloodFlowTrixi.jl/blob/03a78be28...
Normally you want to specify "up to which major version" or "up to which (major, minor) version" your lib is compatible with, while allowing that all minor or path respectively are automatically upgraded.
EDIT: To the person who said "Of all the languages, it often seems like Julia has the coolest libraries"
It's just a very good language for writing libraries. Which is a crazy thing to say, because you're think that being good for writing libraries is something that every language would want to get exactly right, but it appears not.
