It looks like only Program O is regularly updated - all other libraries like Program D, ProgramAB, pyAIML and ProgramR are outdated! I’m using pyAIML for my project and I saw it follows specification 1.0.1 (but doesn’t implement format attribute on dates) and I’m shocked. I know it’s not your problem and problem of maintainers, but do someone know what happened with all of them after 2014? It looks like they’re totally abandoned…
