unfortunately MCNL stopped at 2007.1 there are some of us lonely folks still tryihng to figure out 2008/2009 but the scripting changes required are HUGE so I anyway am looking at several different alternatives.
I can tell you that MCNL is awesome and will probably server 99.99% of your needs (I have it installed on over a dozen pc's right now) BUT if you have something that REQUIRES a newer kernel check out
http://www.pclinuxos.com/ it is a derivative of MDV, similar to MCNL but I BELIEVE they use a newer kernel.
I do NOT believe they use the MOST recent, and their screens all say 2007, but they do have a version labled 2008 out.
it to is a pretty decent product, I use one of THEIR derivatives as my file/web server.
The one thing I dont like about PCLOS is its use of the synaotic package manager, but thats just a personal preference.
