There is a bug in the volume medium node while loading old scenes. The new "Lock Step Lengths" option should be enabled by default, but it is disabled and with wrong "Shadow Step Length" value, set to 0.0. Both issues will be fixed in the next build, but meanwhile if you enable the "Lock Step Lengths" option in all the volume medium nodes, the rendering should be fine.
Thanks for reporting this issue!
