I got the code from SVN, so how can it be outdated?

I doublechecked the SVN web also, at
http://svn.reactos.org/svn/reactos/trunk/reactos/include/ndk/ketypes.h?revision=37792&view=markup.
This is updated, as far as I see. I am quite confused now.

So where is the svn repo of the latest code?

Thanks,
J
