Currently Qt4 is only supported by the recent professional edition. The community edition is much older (still version 2.0) and based on Qt3. Therefore the available community edition is unusable on most Linux distros as most of them have switched to Qt4 a long time ago. (Even with Qt3 legacy support enabled within the Qt4 libraries, the community edition does not work, because the Qt3 legacy support lacks a lot of features of the real Qt3 library)
Are there any plans to publish a more up-to-date community edition (based on Qt4, for example QCad 2.2 or even 3.0) after the professional edition has moved on towards version 3?
