In 1.3.1 pre6, the default FOV is 20 degrees less than in 1.3.0 Final (25 versus 45).
Thus, the distance at which the camera stops from an object after a goto (keyboard g, script goto) will need to be adjusted accordingly.
For an example, select Saturn and then press g. The rings are off-screen. If I remember correctly, in 1.3.0 F, they were on-screen.
