Support Policy for ESP8266 NonOS

Starting from December 2019,

We will not add any new features to the ESP8266 NonOS SDK.
We will only fix critical bugs in the ESP8266 NonOS SDK.
We will only maintain the master branch of ESP8266 NonOS SDK, which is a continuously bug-fix version based on v3.0. This means:
- All other released branches will not be updated.
- All the future versions will be released from only the master branch mentioned above.
It is suggested that the ESP8266_RTOS_SDK, instead of ESP8266 NonOS SDK, be used for your projects.

The latest ESP8266_RTOS_SDK allows users to develop applications using an architecture that are compatible with the SDKs of all Espressif chips, including ESP8266 series, ESP32 series, and the upcoming new series of chips. Switching to ESP8266_RTOS_SDK will helps users to:

Eliminate the necessity to maintain more than one applications (for different chips), thus greatly reducing maintenance costs.
Easily switch to other Espressif chips in the future for enhanced flexibility, less dependency, and reduced time-to-market.

Thank you for your interest in Espressif products.
