CC Creator 0.3 is now available, with some new features plus fixes for a few major bugs. You can get it here.
Notable in this update:
Compatibility options can now be configured (compatibility testing is still not available).
The Export feature now confirms before overwriting existing files.
The Path tool has been modified to deal more intelligently with force floor and railroad crossovers.
The wire loop-freeze bug has been fixed, along with the bug that prevented copying a selection with monsters to the clipboard.
