Monterey (MacOS 12)

[support]

Unlike Windows who guarantees backward compatibility with each previous version, and when the compatibility is brocken, they publish a note to warn the users, everything can happen with MacOS and nobody is informed.

So the best way to be sure that a software works correctly with a new major OS version is to run all part of its code, which means to execute all functions, which is not easy.
We can presently say that we did not see any problems with the functions we ran.
