IOS sdk 4.3 and camera effects like mirror, blur, thermal... etc?

There were many voices about camera effects on IOS SDK 4.3 (as you can read here), after the final release i can't find anything about that on Apple API change log. Was it my fault and 开发者_如何学Ci made inaccurate research with google and Documentation ? Anyone knows anything more about this subject ?

These effects are available via PhotoBooth on the iPad2 but not in the SDK as for as I am aware. Looking at the names PBThermalFilter for example it'd seem that may be the case.
