This one is a bug-fix release addressing:

• When grid dimension was not specified in the input file, it didn’t fall back to its default value of 3, resulting in a smaller stencil (of node averaging) than normally would be used.
• Another bug fix affecting the accuracy of 3D node averaging.
• Entropy fix in Roe solver was not correct.

There are no changes to the input file interface. If you have run cases without specifying the dimension in the input file, you are likely to see noticable improvement with the new version.
