This release contains a lot of improvements, bugfixes, better error handling and comforming HASSIO guidelines.
But above all, this release supports the possibility to control not only yeelights but any other RGB and CT light type that you already have setup in HASSIO!
Trials will tell whether HASSIO and the specific light is fast enough to give a good user experience.
In my case I've been able to control different WiFi lights, even my Zwave light dimmer was surprisingly fast.
The possibility to control yeelights directly will offcourse stay in place.
The communication to the TV has been changed in accordance to the HASSIO guidelines.

The library haphilipsjs has proven to be fast enough and is already used by HASSIO itself.
Therefore it will be used instead of doing direct API requests to the TV.
