Version 0.9.3
21st April 2013
23rd April 2013
By Richard Davey, [Photon Storm](http://www.photonstorm.com)
@ -25,9 +25,9 @@ V0.9.3
* Re-built Tilemap handling from scratch to allow for proper layered maps (as exported from Tiled / Mappy)
* Tilemap no longer requires a buffer per Camera (in prep for WebGL support)
* Added shiftSinTable and shiftCosTable to the GameMath class to allow for quick iteration through the data tables.
* Added the new ScrollZone game object. Endlessly useful but especially for scrolling backdrops. Created several example tests.
* Added the new ScrollZone game object. Endlessly useful but especially for scrolling backdrops. Created 6 example tests.
* Removed the need for DynamicTextures to require a key property and updated test cases.
* Add the rotationOffset value to GameObject (and thus Sprite). Useful if your graphics need to rotate but don't weren't drawn facing zero degrees (to the right).
V0.9.2
