3.04 is the latest version/recompile, but the 3.01 text within the maps themselves was never changed to reflect updates. I have no issues with IR either. I never really use bercon gradient so I can't speak to its stability, but never had any issues otherwise except for this:
If you are using multitexture with bercontile, and you copy the nodes over to make a new setup, that will usually not only crash MAX, but will make your file unstable where it will crash once you open the material editor. So you have to start from scratch for a new material when using this combo to avoid the issue.
