Hi,
that is not a bug. You had set "Clamp" to 0.8 in 2.69.

In 2.70 we expanded the setting, so you can now set the Direct and Indirect clamp. This leads to backwards compatibility loss, so you have to enable clamping again. That is noted in our release logs as well, see "Backward compatibility breakage" here: http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.70/Cycles

Thanks dingto, sorry for the inconvenience caused. Hope that blender can automatically change thin in future.
