Rolf release RCG tag 2.8.4 today. I have installed it on h1build, and compiled/installed all SWWD IOP models against this. I also compiled h1lsc model but did not install, just to check the compile.
I am testing the new SWWD models and MEDM on the EY SUS and SEI systems at the moment.
All release pointers have been set to RCG-2.8.4, please keep this in mind if you build FE models.
