INSTRUCTIONS

If you do not follow these instructions, your issue may be dismissed.

1. Follow the checklist under Basic Infos and fill in the [ ] spaces with an X.
2. Fill in all the fields under Platform and Settings in IDE marked with [ ] (pick the correct option for you in each case, delete the others).
3. If you haven't already done so, test your issue against current master branch (aka latest git), because it may have been already fixed.
4. Describe your problem.
5. If you have a STACK DUMP decode it:

6. Include a Minimal Complete Reproducible Example sketch that shows your issue. Do not include your entire project, or a huge piece of code.
7. Include debug messages:

Problem Description

Previous ESP8266 Arduino releases came with a set of useful pre-processor defines in cores/esp8266/core_version.h

#define ARDUINO_ESP8266_GIT_VER 0x2843a5ac
#define ARDUINO_ESP8266_GIT_DESC 2.7.3-3-g2843a5ac
#define ARDUINO_ESP8266_RELEASE_2_7_4
#define ARDUINO_ESP8266_RELEASE "2_7_4"

The latest 3.0.0 release is missing ARDUINO_ESP8266_RELEASE_3_0_0 which would be useful to identify the latest release:

#define ARDUINO_ESP8266_GIT_VER 0xefb0341a
#define ARDUINO_ESP8266_GIT_DESC 3.0.0
#define ARDUINO_ESP8266_RELEASE_
#define ARDUINO_ESP8266_RELEASE ""

MCVE Sketch

#include <Arduino.h>

void setup() {

}

void loop() {

}
