Previously, using the "Stride Bone" tried to get that Bone motionless on the path by correcting the internal time of the Action. This however caused too many problems, especially with irregular walks. The new system also tries to keep the Stride Bone motionless, but this by moving the entire armature, and not changing the timing of the Action. Give much nicer results. :) To make editing Strides easier, I've added a new option in the NLA panel to disable the path. This way you can quickly switch to editing the action itself (keying the stride bone) and viewing the result.
