shaderProgram in cocos2d 3.0 doesn't work

I have just started with Cocos2d 3.0 after using 1.1 for a long time. I wanted to test the shaders out and looked up some tutorials. All tutorials seems to use the CCSprite property "shaderProgram". When I try it like this: ``` renderTexture.sprite.shaderProgram = [[CCGLProgram alloc] initWithVertexShaderByteArray:ccPositionTextureA8Color_vert fragmentShaderByteArray:ccPositionTextureColorAlphaTest_frag] ``` Xcode gives me an error saying: "Property 'shaderProgram' not found on object type CCSprite *" Is this property removed or changed from version 2.0 to 3.0 and how would I go about using it in Cocos2d 3.0? Thanks!
