From version 0.3.0 to 0.3.1:

Version 0.3.1 is a bugfix release.

• Scattered data interpolation. In both 2D and 3D, fixed bugs that caused seg faults when trying to do scattered data interpolation.
• Minor updates for TSTT. Added a configure option for VTK-format input into GRUMMP. Fixed several compile errors when logging is disabled. Also tweaked a couple of things in the main Makefile.
• Length scale reporting. A bug in 0.3.0 made it so that the edge length scale info reported after mesh re-ordering was incorrect; this has been fixed.
