Oh no, I'm not maintaining the current Common Music (v3).
I'mk trying to keep Common Music v2 in an operational shape (CMv3/Grace
moved to an embedded Scheme (s7) and away from Object Oriented
Programming). There are still quite some folks out there using CMv2, and
the book "Notes from the Metalevel" by Rick Taube uses version 2 as well.

You'd need to look at branches/cm2 ...

Thank you, this, together with Robert Brown's hints, is very helpful.
