We are currently planning to update our primary builds. Next to the new Ubuntu LTS release we have two Windows builds and one machine for Mac OS X, which are in need of a general overhaul. A first casualty will be the Universal binaries on OS X: the new build machine will only build for Intel architectures.
Another issue at hand is the binary compatibility of our new builds on Windows with existing plugins for Instant Reality written on Windows. So far we have compiled everything using Microsoft Visual Studio 2008. We currently have an open debate internally whether to move to Visual Studio 2012 or 2013 directly and invite you to pitch in: please send us an eMail or join us in the forums if you are developing or plan to develop for the Instant Reality platform, whether it’d be InstantIO hardware plugins or X3D node pools, and tell us which tools you use on Windows. Thanks!
