The behavior when you add a keyframe in the Animation Keyframes dialog box has changed a bit for the worse between PV 3.4 and 3.6. Before, when you added a track, then opened the keyframe editor for that track and click the "New" button to add a keyframe, it would create one with the time and value in between the two existing values. Now it basically duplicates the first keyframe. To replicate:

1. Create a Sphere source.
2. Open the Animation View.
3. Add a track for Start Theta.
4. Double click the new track.
5. Click "New".

The new track is also at time 0 and its value is 0. Before the added track was at time 0.5 and had value 180.

It looks like this change comes from some changes in how keyframes are added. It looks like the New keyframe now adds a keyframe before the selected keyframe, and if none is selected it adds it "before" the first one. That seems like odd default behavior. Perhaps a special case it should add it after the first one and before the rest.
