There is an “unofficial build” of PabloDraw by necro that contains some minor improvements but has also been built against more recent mono libraries. It’s more stable on recent operating systems and apparently fixed memory leak issues on MacOS. The binaries are available here: Necro's Pablodraw builds

A new official build of PabloDraw is due in a few weeks. It will be updated for .NET 5.0 and run on MacOS BigSur. It will run on Gtk+3 and no longer require mono on Linux.
