I’d never paid attention to certain version numbers, and release dates, of certain applications. And, frankly, always assumed that things were up to date.
Apparently, that assumption was likely mistaken.
$ bash --version
GNU bash, version 3.2.57(1)-release (x86_64-apple-darwin18)
Copyright (C) 2007 Free Software Foundation, Inc.
The copyright on that specific version on the state of the art macos — all Macs — was 2007. TWELVE years ago.
What version is currently available? Unsure, but I’m going to bet that it’s most certainly not v3.2.57(2).
Ah, yes… it’s slightly newer:
Isn’t quite as state of the art having GPL-software that’s static. Yeah, I know, it makes things more stable. I get it. But there will be some newer capabilities, improvements, bug patching and so forth that will be revealed with the continuing march of progress.
Now… what are the risks to doing the upgrade?
