 Version 1.1.3 - in build
 
+* New: Added a .jshintrc so contributions can be run through JSHint to help retain formatting across the library (thanks kevinthompson)
 * New: Added a new in-built texture. Sprites now use __default if no texture was provided (a 32x32 transparent PNG) or __missing if one was given but not found (a 32x32 black box with a green cross through it)
 * New: Added Phaser.Filter. A new way to use the new WebGL shaders/filters that the new version of Pixi supports.
 * New: The object returned by Math.sinCosGenerator now contains a length property.
