I actually liked the old one better, though that may be a matter of taste. If you're going to go the color-coded route, with visual indicators of data rather than text, I think you'd be better off using a series of icons with a legend at the top of the page. It'd be a lot faster scanning through the list. Especially for Voice Acting, Additional Mods, and Released, since there are maybe 6 icons you'd need at most for those (Yes for voice acting, Yes for additional mods, and Not Released/Demo/Party released/Fully released for campaigns). No for voice acting and additional mods could be indicated by the absence of the icons. You'd buy yourself a lot of extra space too, because it'd save space for the 16x16 icons than 50px wide columns.
In the absence of icons, you could also have separate (untitled) columns, one for "V", one for "M", and one for "N/D/P/R".
On the subject of saving space, "Missions" is redundant after the number of missions in each campaign. It could be reduced to just the number of missions. As long as you don't have any similarly-formatted numbers it should be fine that way.
I do like the idea of grouping the campaigns by chronological order. It could be interesting to play through all of the user-made campaigns from pre-pre-pre great war to post-post-post-Capella and see how they work out.
