I found way to be ok. It's 2.4.2 bug.
u can edit ESP8266mDNS.cpp like this.
/**

• STRINGIZE
  */
  #ifndef STRINGIZE
  #define STRINGIZE(x) #x
  #endif
  #ifndef STRINGIZE_VALUE_OF
  #define STRINGIZE_VALUE_OF(x) STRINGIZE(x)
  #endif

addServiceTxt("arduino", "tcp", "board", STRINGIZE_VALUE_OF(ARDUINO_BOARD));
