I just started a new Malden campaign (yes, with the new "Malden" map!) on the server (the Tanoa is still there, don't worry). This one uses the latest release version of "Liberation" so it has some new version like starting from an aircraft carrier and also more complex resource management. You now have to build storage facilities to store the resources as well. There is probably more, but I haven't checked all the changes.
It uses vanilla Arma, so no RHS mods needed.
