Hardware

Hardware: ESP-01
Core Version: 2.3.0

Description

I am using Arduino v1.6.9 on Windows 7 and was using esp8266 library v2.2.0 which was working perfectly. Yesterday, the IDE popped up a message saying the board has an update, so I went ahead and upgraded the library to v2.3.0. Now, I am not able to compile any sketch.

The board selected is "Generic ESP8266 Module", just like before. What is the problem?

Debug Messages

Board generic (platform esp8266, package esp8266) is unknown
