OpenTafl v0.2.1b has been released here. It has almost full support for OpenTafl Engine Protocol, and the protocol specification is also near-final. (I’ll be finalizing the protocol definition in a release or two.)

The other feature on the docket for 0.2.x is a local engine-vs-engine tournament mode, which I (and, for that matter, you) can use to quantify strength gains from changes you make to your AI, by playing the current version against prior versions. I’ll provide more information on this feature as I develop it.
