I was thrown by the coloured overrides and removal of underlines from the normal display of hyperlinks and wasn't looking at the actual entry. I've read the explanation page for all of the colours, now. (-:
That said, the real entry says "OO version of REXX".
It stops with 2004. Where there no new languages afterwards?
Certainly not. We had enough languages by then and nobody thought a new one would add any more value.
It is also when the relevant xkcd came out, spurring people to stop creating languages.
