I have Reality 2.5, compatible with Studio 4.5, ready. The problem is that, until Studio becomes official I can’t release it because 2.5 cannot run inside the official version of Studio, version 4.0.
This is one of the many problems about releasing public betas, they mess things up, especially when there is no backward or forward compatibility for plug-ins.
Rest assured, though, that Reality 2.5 will be out as soon as Studio 4.5 is officially released. I probably don’t need to say this, but, anyway, it will be a free update
