You are now able to show your current sensory information with command show
senses. Senses were actually implemented in game long time ago so nothing else
is new but making the information available to players.
Your abilities to sense affects how much information you can gather from the
world and some of you might have noticed that certain races sense better
certain things than others.
I would also like to point out that magic-sense does not mean see magic
ability but more like ability to point out if there are 20 conjurers in the
next room summoning an army of demons.
