Right, that one. The last 3.x release. If this release were a person,
it would be in high school by now.

My guess is that you'd previously installed bash with homebrew or
similar, so the script was being interpreted with bash 5.x. After the
upgrade it started being interpreted with the stock bash (3.x). Does
that sound plausible?

It's a good idea to install the newer bash (e.g., with homebrew) and
to point /bin/sh to it. Having an ancient sh interpreter is bound to
create friction.
