Comes with a simple in-game hotkey manager for you to assign and change assignments for equipment pieces to hotkey slots. It handles the equipping of bound items for you and also checks to make sure you have the item in your inventory before equipping it.

  What's new in v1.2? - More robust item binding. - Proper support for hotkeying Aid items in Survival mode. - Miscellaneous code tidying and tune-up.

Just the framework. Doesn't add anything to the game other than enable hotkey support. You can then configure your hotkeys manually by editing Hotkeys.ini.
