We are currently working on version 5.4.
5.4 will be a pure technology upgrade in the following main areas:
– new VS2008 compiler support;existing .NET applications compiled with VS 2005 are still working properly
– Updated DWG libaries will support Autocad 2010/2011 format
– new Infragistics UI libaries

Clients interested in testing the 5.4 Beta are requested to send me an email.

Thank you,
Andreas Fleischmann
