Previous versions of Julia Pro shipped with launchers for three applications to use Julia: the REPL, Juno and Jupyter. Version 220.127.116.11 starts Juno by default.
It is more or less easy to find the folder where Julia lives and launch the REPL manually (and nevertheless, the command window of Juno is basically the same as the REPL, although it takes a bit more time to start.) But I cannot find such an easy way to start Jupyter. Is it not pre-packaged anymore, and should I install the IJulia package?
