4.1 to 4.3 animation component

Guys, is the animation component of the unity 4.1 and 4.3 different? because every time i create a simple transformation animation in 4.3, the “Animator” component is being added. While in 4.1 when creating a simple animation, it creates the “Animation” component. is there any difference between the two? because i want to generate the “Animation” component instead of the “Animator” component in the Inspactor view in Unity 4.3. is there any possible way?

If you first add the legacy Animation component to your GameObject before creating the curve, then it won’t automatically add the mecanim Animator component.
