I see "Micro: compiling micro library (~64K) for the embed system", now that caught my attention! Should I then assume that the compatible platforms are actually more than the listed Windows, Linux, Mac, and mobile OSes? I'm on the front of AVR development, and cool new things always arrive late (understandably, if they arrive at all...) to our little corner of the world :( But I assume that "embedded" here will mean mainly ARM. (similarly, I'm still excitedly waiting for more progress on the Rust front :)
