As an alternative to the stressnet, @jeffro256 and I have been discussing releasing clear instructions on how to run the latest FCMP++ implementation instead, currently in this fcmp++-stage4 branch, as well as making an issue tracker that states what features are still being worked on [..]

Work overview

Merged PR's:
* Modified PoW hash for FCMP++
* Prohibit torsioned outputs at consensus starting at the FCMP++ fork
* Incorporated composition changes to tree building [..]
Other tasks:
* Tx weight analysis
* Blinds cache
* FFI cleanup
