New Engine:

Puffin
https://github.com/kurt1288/Puffin/releases/tag/1.0.0

Would Linux and/or Mac binaries be helpful to anyone?

As for KhepriChess (my other engine), I've decided to indefinitely stop work on it. Unless some improvements are made to the V8 javascript engine, I don't know if there is anymore progress for me to make with it.

According to the gauntlet I ran against 7 other engines: 2577. Though I'd probably be more comfortable underestimating it and saying closer to around 2500.
