Unable to compile examples with ESP Arduino v2.0.0

[ashthespy]

I seem to be unable to compile any of the examples with v2.0.0. The error I get is

\Arduino\libraries\arduinoWebSockets\src\WebSockets.cpp:28:35: fatal error:core_esp8266_features.h: No such file or directory  #include <core_esp8266_features.h>

I am a bit new to git, so I am using this library with Arduino 1.6.5 along with the board manager.
But according to commit 92a63e9, it should work right?

the ESP core itself needs an update too, but this update is not released via board manager yet.
you can follow this:
https://github.com/esp8266/Arduino#using-git-version-
to get the latest core, then It will work again.

I initially tried manually including core_esp8266_features.h and the lib64 folder contents, gave up and then used the current git version.

All is good now :)
