I just upgraded from Julia 1.1.1 to 1.2.0*. Part of my workflow involves IJulia notebooks. Currently, anytime I try to launch and IJulia notebook, it launches a 1.1.1 kernel with no option for a 1.2.0 kernel, even if I launch the notebook from within 1.2.0

What extra steps do I need to take to fully upgrade to 1.2.0 and use the newer version in an IJulia notebook?

*To upgrade I put the Julia 1.2.0 folder in /opt/ and changed the symlink in /usr/local/bin/ to point to the new Julia executable

I figured this out shortly after posting. The solution was to delete (or move, I chose to move) the /.julia directory and rebuild it with Julia 1.2.0, including reinstalling IJulia. The new version of Julia is now available for launching kernels for Jupyter notebooks

    Note that you don't need to delete/move the `.julia` directory. Simply `]add IJulia` in the new version should be sufficient. Multiple versions happily co-exist together. – mbauman Aug 22 '19 at 21:01

    Just `]add IJulia` might not be enough if `IJulia` is already available on the system (e.g. for Julia 1.1 as in this example), you also have to rebuild IJulia (`]build IJulia`). – fredrikekre Aug 23 '19 at 07:30
