Actually, you should nowadays use

M-x ess-version

which tells you more (the subversion revision number, *and* its date)
.... and indeed, the current development version still carries the
"12.09-2" version string....  mainly because it still does not contain
much more than 12.09-2.

To your main question: Yes, Vitalie had planned to look at R Markdown support,
but he has not finished that yet..
