+## Library Changes
+
+### v1.1.0
+
+The callback function `void delay100ms()` has been removed as this was not compatible with ESP32. The application should
+change the code to:
+
+```c++
+ // Send temperature twice with 100ms delay between packets
+ OregonTHN128_Transmit(&data);
+ delay(100);
+ OregonTHN128_Transmit(&data);
+```
+
+AVR targets can replace `delay(100)` with LowPower usage:
+
+```c++
+ LowPower.powerDown(SLEEP_15MS, ADC_OFF, BOD_OFF);
+ LowPower.powerDown(SLEEP_60MS, ADC_OFF, BOD_OFF);
+ LowPower.powerDown(SLEEP_15MS, ADC_OFF, BOD_OFF);
+```
