As an update to this thread, in 2020 Ray Newman retired from maintaining Mumps V1 and I took over for him. I
renamed it Reference Standard M (RSM), and the current version is V1.77.0, but version V1.78.0 is just around the
corner. I have been actively developing it in my spare time since late in 2020. So that means that the original
Mumps V1 repositories are now deprecated, as they haven't had any development since 2018, and are no longer
maintained. I keep an archive of the last release from Ray on my Gitlab account as well.
To keep your list up-to-date, here is where you can find RSM - https://gitlab.com/Reference-Standard-M/rsm
