+## Changelog
+
+## v2
+
+1. k3Menu objects now have stylable properties ala CSS
+2. Exposed `game.ui.obj` "base object" which allows you to create your own widgets
+3. Revamped the animation system to one with blend trees
+4. Added scrollboxes and image objects to k3Menu
+5. Replaced the font subsystem with one that uses TrueType fonts directly, and they are drawn using signed distance fields when possible
+6. Added `game.near` and `game.far` values for editing the camera planes
+7. Added vsync parameter to command line
+8. Graphics bug fixes
+9. Improved mipmapping
+10. Frustum culling
+11. Added support for 32-bit indices in models
+
+## v1
+
+Initial release.
