Apple Replaces Bash With Zsh as the Default Shell in macOS Catalina

'Starting with macOS Catalina, Macs will now use zsh as the default
login shell and interactive shell across the operating system. From a
report:

All newly created user accounts in macOS Catalina will use zsh by
default. Bash will still be available, but Apple is signaling that
developers should start moving to zsh on macOS Mojave or earlier in
anticipation of bash eventually going away in macOS. Apple hasn't
explained exactly why it's making this change, but bash isn't exactly
a modern shell as it's implemented in macOS, and a switch to something
less aging makes a lot more sense for the company. Apple is stuck
using version 3.2 of bash that has been licensed under GPLv2, as newer
versions are licensed under GPLv3. Apple has kept clear of using GPLv3
packages in macOS as the license is generally more restrictive to
companies like Apple that sign their own code and it includes explicit
patent grants, '
