The latest release (SigmaPipe 2.3) is a "deeply debugged" version which features several significant improvements.

Two chemical engineering students (Stephan Lilje and Daniel O'Keeffe) from The University of Western Australia have spent their summer vacation doing extensive stress-testing and formulating concepts to improve user-friendliness.  The result is that several bug layers have been uncovered and eliminated.  In addition, features such as keyboard 3D scene movement have been brought into line with "natural" expectations.  Other changes include addition of information relating to fluid composition and condition (in any part of the line), plus a folder content manager to make housekeeping easier.

Training material has been updated and most of the tutorials are now accompanied by a YouTube video (thanks to the editorial efforts of Stephan and Daniel).
