The previous version contained smaller but significant changes and I warned their could have been some introduced errors. Unfortunately, this did occur and Version 188.8.131.52 largely contains bug fixes and extended DXF support.
DXF support now includes more entities - text is not yet supported, but will be added soon.
New expiry date extended to 1 October 2014.
The camera occasionally rotated unexpectedly in plan view.
Mapping in the scene did not always show the poles in the correct locations on the stereo-net.
Selecting scene meshes in Clipping Mode did not always highlight the correct layers in the grid.
Various coding changes to enable and simplify future additions.
Thanks for the e-mail feedback on the errors, and apologies for the slow response time to correct - I was travelling and also have slightly too much on my plate at the moment :)
