And the ability to pass your turn.

Today’s small update has a couple notable changes:

Reapers will now follow you into other regions (but not into tunnels or dragon lairs).

It is now possible to skip your turn without doing anything. To pass your turn, open the Options dialog and click “Pass”. If you pass while in stealth, the chance of being spotted is the same as if you were to sneak onto the tile that you are currently on. Passing can be helpful in tunnels against slimes, if you are still in stealth and you want to stand still while they move. Passing can be useful in other situations too, but those cases are extremely rare, since guarding will almost always be a better option than passing.
