In the Features page it says:
2013. Aug. 08. (Thursday)
On the Documentation page there are links to RT2.4, RT3.0 and RT4.0, which then link to rawpedia.
I think the page should either be updated regularly, which I understand is work intensive, or information that is old and misleading and needs constant updates should be removed completely. If I get to software’s page I prefer having little but correct information, than the instant feeling that this program is possibly old or dead or at least not updated anymore.
Just my feeling…
