You may have noticed that ISI posted a changelog a couple of days ago with a list of fixes and additions to be included in upcoming rFactor patch. rFactor Central has a great four page preview highlighting some of the goodies we can expect from 1.140. The preview features screenshots and a few videos of some of the new tracks that will be included with the patch. It also mentions that other than a few glitches here and there, existing mods seem to work fine with the latest update. There's lots of good info in the preview so go check it out.
