Some time ago I slimmed down the Quiescence Search of the diagram's AI, because in large variants with many powerful pieces it was still prone to search explosion. (It now unconditionally searches only Low x High captures that capture the last-moved piece, or punish moving away a (soft-)pinned piece; other captures need to consume part of any remaining depth budget.) Because of this diagrams that used impractically long thinking time might now perform acceptably. For instance, after this change I had no problems having the Diagram play Macadamia Shogi against Ai Ai. (But I still don't want to add Macadamia Shogi to the list, because it is not possible to enter the triple capture of the Lion Dog. Even though in practice there probably will never be an opportunity to make such a capture.)
OK, I added those to the list.
