Hi, I’m using a package cloned from github in Julia 1.3.1

The owner of the package updated the code recently. I would like to try the new version, but since there is no corresponding version number, I wonder if it is possible to go back to the current version I’m using, in case something goes wrong after updating it.

Thank you!
