I changed the HUD to be a bit more familiar when coming from Legacy. It's now on the bottom right and gives a lot more information.
One thing I found in the previous HUD iteration was that hunger, being cold, being poisoned.. they all meant nothing. The small icons didn't make it obvious what was happening. They didn't make it clear just how close or far away from starving you were.
We have notifications for radiation, bleeding, hot, cold, freezing, starving, dehydration, drowning and wet.
