but this is the list from what I can recall: - removing expand animation (it is a case of grow animation) - removing AbstractAnimation and using QAbstractAnimation as the common base - animations are non longer factories, but real animation (so it is just no issue to mesh then with user created animations) - animation group will correctly revert the direction of all subanimations (useful for rewinding an animation) - fixed opacity effect in pulse animation (now it works correctly) - there is not 'forward' property, but animation 'direction' (this is how rewinding an animation must be done) - direction now is movementDirection property (used in SlideAnimation and RotationStacked) - the weakpointer for the actual animaiton is non longer in AnimationPrivate but in each specialized animation class - hide property is being removed (in progress) since it really is a case of Fade I guess this is it, now is just a matter of iron out the remaining bugs and polish the public API. svn path=/trunk/KDE/kdelibs/; revision=1057993
