v1.4 brings fixes to joystick controls (should hopefully fix looking around on all types of controllers). Oculus Rift updates have also been made -- GUI elements shouldn't overlap incorrectly, among other fixes.
There was a rather large balancing tweak made for v1.0, so if you are running an older version, you really want to update as prices were changed & damage tweaks were made.
