TL;DR:

• 2D physics interpolation: Should heavily reduce jitter and make the game smoother on higher refresh rates!

• TileMap layers are now separate nodes: Each layer is now its own node. This is huge because it means it’s easier to manage, easier to iterate over, and each layer can have its own settings and move separately.

• Option for checking for engine updates automatically

• Reverse Z for the depth buffer: They made a blog post about this a few days ago.
