Concept 3.0 is now finally available. The server itself is stable (the engine is available since version 2.6), but now the also Concept Client 3.0 is available.
It comes with a brand new IDE, Concept IDE 2.0.
Glade was dropped in favor of RDesigner, a Concept-native UI designer that can handle both glade and the new Concept UI XML format.
I've started a face-lift for GyroGears. It will also include a "Custom form designer" based on RDesigner that will allow the developer to define specific forms when needed, replacing the gyro auto-generated forms.
The final release is planned on the 10th birthday of Concept, in about two weeks. It will include the Concept Client 3.0 deb package and OS X image.
