Sometimes when I am developing a package, I want to see how the changes might affect one of my projects. Typically, I do the following:

Activate project environment:

`] activate MyProject`

Switch the development version of package:

`] dev MyPackage`

After examining how the changes in the package affect the project, I want to revert back to the registered version of the package. How do I do that? Thanks!

```julia
] free MyPackage

```

Note that you will probably need to restart your Julia session to see the changes (though if you are using Revise it might be able to update your running session).
