| − | Thanks to careful design and insistence on implementation/evaluation, the X3D International Standard has maintained both steady growth and interoperability ever since Virtual Reality Modeling Language (VRML) in 1997. This track record of stability and innovation is among the best in the 3D graphics industry.

| − | [[X3D version 4.0 Development]] efforts are focused on HTML5/Declarative 3D/X3DOM and Augmented Reality Continuum (ARC) technologies, which may require architectural changes. Some new technologies may get pushed from 4.0 to 3.4 (or back again) after careful consideration by the respective working groups.
