Hi, i have a problem with my project after updating to Unity 5.2. Animator.stabilizeFeet stop work in Unity 5.2 in my project. Maybe need another way to enable this feature in 5.2? It very important feature to my gameplay, please help me solve my problem. 
If you have more than one layer this is a know issue and a fix is comming in a patch release
Hei, people often refer to a mecanim blog post at Unity Blog
where they talk about ‘Original hands and feet position’:
…Those original positions and orientations can be used to fix the retargeted skeleton pose to match the original world space position using an IK pass…This is what happens under the hood for feet when “Foot IK” toggle is enabled in a Mecanim Controller State.
For me this sounds like we should be able to handle this on our own. I wonder if a call to something like SetIKGoal(GetIKGoal(…)) in OnAnimatorIK() for the feet (or hands) would be sufficient? Can we do the ‘under the hood’ on our own? Does GetIKGoal() give us the ‘Original hands and feet position’? Anybody from Unity?
yes calling GetIKPosition/GetIKRotation will return the position/rotation as evaluated by the animation curve from your animation clip and this is true for all layer. You don’t need to call set(get()), you only need to set the weight to 1 in this case as the IK position/rotation is already setup correctly
