current state of ESP8266 version

[mentaluproar]

I see in the documentation there is support for ESP8266 and in the latest version it can be built under the Arduino IDE. I cant get the Arduino IDE to build for it, as it is missing a dependency I just cannot seem to satisfy, ESPAsyncWebServer. I have installed ESPAsyncTCP but it's not working so I'm guessing that was the wrong library. First question: how do I satisfy that dependency?

Second, according to the notes, UDP isn't implemented yet. However I see it in the GUI screenshots. Is that notation out of date or is it still unfinished and I should use serial instead on an ESP?
