The Apple Pencil Pro has a new sensor in the barrel that accepts your squeezes. This action can do things like bring up tool palettes so you don't have to manually tap into them with your free hand. Apple says you can also use the gesture to activate shortcuts or and other actions.
Haptic feedback lets you know when the squeeze was accepted or when something you moved has snapped into place. Apple also added a roll gesture for precise control of whatever tool you're using, powered by a new gyroscope.
The new Apple Pencil works with Find My, so you'll have some extra assistance when you lose it. Apple says developers can make their own actions with the new gestures, so you can expect to see customizations based on the iPad apps you're using.
