The new output system is now in place within MOOSE and will soon be the only output system. The completed new system will be merged in the coming days and the old system disable in MOOSE. However, INL internal applications such as BISON and MARMOT will have the old system enabled so that they may be upgraded individually.
This is a big change affecting every MOOSE application, we appreciate the patience everyone as shown so far, it will be worth it. The new system will provide much more flexibility as we progress.
For additional details on the new system check out the wiki documentation: [Outputs]
