 ## TO DO
 
 1. Similar library for ESP8266 and ESP32
-2. Longer Interval for timers.
+
+
+## DONE
+
+For current version v1.0.1
+
+1. Longer Interval for timers.
+2. Reduce code size if use less timers. Eliminate compiler warnings.
+3. Now supporting complex object pointer-type argument.
+4. Fix some bugs in v1.0.0
+5. Add more examples.
