Files don't compile anymore with ESP8266 Boards Version 3.0.1 about esp8266-weather-station HOT 4 CLOSED

The list of breaking changes is quite long :( https://github.com/esp8266/Arduino/releases/tag/3.0.0

from esp8266-weather-station.

from esp8266-weather-station.

The whole project compiles fine against 3.0.2 (what CI uses).

from esp8266-weather-station.

Sorry, here it doesn't compile.
