One thing I forgot to mention with High Sierra was what nano version it ships with. I haven’t used nano for a long time, but I’ve referenced it as a bellwether on Rubenerd over the years to show how fresh bundled macOS software is.
The current version is 2.9.2. Firing it up on my 10.13.3 box:
GNU nano 2.0.6
I must have made a typo with my El Capitan post in 2015 when I said that shipped with 2.0.9. Either way, is another overused phrase. It also means no update in at least a decade.
Vim fared better:
VIM - Vi IMproved version 8.0.642
