LuxRender 0.8RC1 released

This release is the first to embed GPU acceleration through the OpenCL library. Not all graphic cards/drivers support it yet, that’s why on Linux and Windows the release comes in 2 flavours: with or without OpenCL support. If you experience issues with the OpenCL enabled version, let us know and fall back to the other version until we can fix the issue. Right now, only the path integrator with sampling one light source at a time supports GPU acceleration.
