Norbert has done a ton of work to port Magritte3 from StHub to GH. He also
has been steadily integrating the enhancements from my fork . For Pharo
users, it seems that  should most certainly be considered canonical going
forward. For users of Squeak/other platforms, many enhancements have only
been tested in Pharo, so they may work, but they may also have to be tweaked
to work in non-Pharo platforms.
