- Added the redstone comparator
- Has 2 inputs and 1 output
- If A≥B, the output will be A, otherwise it will stay off – When the comparator is toggled, it will output full strength instead of A it will subtract B from A and need a comparator as input for B
- Replacement for the capacitor
- Whichever side gives the bigger signal will be considered signal B
- Added the daylight sensor block
- Output power while receiving sunlight
- The level varies depending on the time zone, and it does not function at night
- Added a hopper block
- Added a trapped chest that activates redstone
- Gives out a signal depending on the amount of players looking inside. 1 person = 1 strength signal, 2 people = 2, etc.
- Crafted with a chest and a tripwire hook.
- Large trapped chests can be staggered with large chests to allow more compact storage.
- Texture is slightly different than a normal chest, with a red stain around the latch.
- Added weighted pressure plates that detects item stacks

- Redstones circuits are more consistent and pistons should be more stable
- Inventory management changes
- Double-click items to fill the stack up as much as possible
- Drag item stacks around to divide them up over the dragged-over slots
- Drag item stacks around with the right mouse button to place one of that stack in each dragged-over slot, if that slot is not occupied already
