Really? I don’t see anything in the github commits. Are you talking about this thread? Upgrading gargoyle to use recent TADS sources.
When garglk was on Google Code I had the project commits in my feedreader and I’d compile the latest version of the code for myself whenever someone made a major new commit. Haven’t bothered with that in quite a while, but I’d jump on it if Chris added support for TADS 3.1.X, regardless of when the official release might or might not come out.
