I'm guessing we call it Oberon-07? The one from "The Programming Language Oberon", written in 2007, revised in 2016. As the documentation states, it's not 100% on specs, for a better fit with Dusk interoperability, but it's very close. 100% specs compliance wouldn't affect implementation size by much.
Ok, I see, thanks; so it's the same version as implemented in OBNC posted above. It's the last version Wirth specified, and quite different from the versions used for the Oberon systems 2, 3 and 4 in the nineties. Personally I consider Oberon-2 the most useful version, but I still had to get rid of a lot of orthodoxies to really use it in my projects (see https://github.com/rochus-keller/Oberon).
