General :
Better support for remote and HPC rendering,
Stabilization on licence management,
Many interface bug fix.
Engine :
New variants are available to create setups from layers or tags,
Variants can now be identified as Light Group to be treated properly in the Batch Renderer,
In the Batch Renderer, frames can now be rendered with different completion criteria for each frame,
In the Batch Renderer, it is now possible to create basic Image Compositing from the output frames, taking the Light Groups in consideration properly. If this option is selected, the option to compile a video from the frames also compiles a video from the composited frames,
The tools to do image compositing and video compilation are now available in independent windows outside of the Batch Renderer.
