Note: Even if you don't own this DLC, you can still play Community puzzles that use these parts.
Curling Stone
A new part inspired by the Winter Olympics. The Curling Stone will slide for a long way on ice or snow. A can be tied to it too.

Kev's Puzzle Pack
Not a real big update here. Now has 4 puzzles. Will continue to add more puzzles in the coming years.

Bug Fixes
There are also a few bug fixes in this release.
- Fixed problem with paths that have characters like "é" in them
- Trapdoor now correctly shows the weak stick
- Removed 'Destroyed' as a starting state for Zombie Tim
- Fixed puzzle auto-advance so it doesn't advance to DLC packs that aren't owned
- Fixed bug with Flying Saucer. It was reversing direction when hitting sensor shapes.
- Made sure the button to switch between physics layers is present on puzzles that have Wonderstruct parts

Future
The biggest thing coming in the future is the Mighty Knights Parts and Puzzles Pack. It integrates seamlessly with all the other Contraption Maker Parts. No firm release date yet. Maybe May or June.
We will continue to add a new part or two each month and also add new puzzles. That's all for now.
Here are a couple of very old screen shots of Mighty Knights.
