Oberon-2 is an extension of Oberon developed in 1992 by Hanspeter Mössenböck that adds stronger object-orientation and brings back a couple of features from Modula-2.
Note that except for the Oberon compilers developed by Wirth himself that in general only support the original Oberon, most developers support both languages without explicitly mentioning it. This is because Oberon-2 is purely an addition to Oberon, and therefore you can program in the earlier variation without any problems. But the literature supplied with the tools does frequently not differentiate correctly between the two.
Active Oberon is a variant of Oberon-2 that has explicit support for programming multicore processors.
Zonnon is a descendant of Active Oberon that adds safety features and a stronger object system.
