Ok, so some hours ago a new recommended build for 1.2.4 has been released. This means that the plugin authors now have a stable version to work with. Now we only need them to release the updated plugins.
In order to upgrade to 1.2.4 we need to have a certain minimum of plugins upgraded to 1.2.4 that enable griefer protection, world transportation and inventory-mangement between worlds. If we are lucky, we will be able to upgrade this weekend! A lot of the important plugins have beta versions out already and I would assume that final version should be quick to release. We might go live with some reduced functionality in the beginning and add other plugins as they are released.
