The linage is more or less as follows:

Oberon => Oberon-2 => Component Pascal

                   => Active Oberon

                   => Oberon.NET => Zonnon

       => Oberon-07 (multiple iterations until 2016)

From features think Go (Oberon), D/C# (Active Oberon).

Active Oberon provides features for manual memory management (untraced references), async/await (active objects hence the name), lightweight generics, interfaces, exceptions.
