A new UI will make it easier for admins to obtain custom items. Just type /mcr items and a GUI will appear containing the items, which you can click to get.

The pre-1.8 adventure mode offers a more realistic approach to survival. I will be improving this a lot. You will only be able to break blocks with the required tool, and you will need to create digging tools to gather flint before you can make a hatchet.

Water will need to be purified before drinking, by burning it in a furnace.

Eating raw food will result in food poisoning - just like rotten flesh.

More sleeping effects have been added, such as blinking.

Logs will fall from above when you mine a tree.
