### Releases v1.2.0

 1. Add support to RP2040-based boards, such as **Nano_RP2040_Connect, RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [**Arduino-mbed RP2040** core](https://github.com/arduino/ArduinoCore-mbed) using WiFi / [WiFiNINA_Generic Library](https://github.com/khoih-prog/WiFiNINA_Generic)
 2. Add support to RP2040-based boards, such as **RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040**, using [**Earle Philhower's arduino-pico** core](https://github.com/earlephilhower/arduino-pico) using WiFi / [WiFiNINA_Generic Library](https://github.com/khoih-prog/WiFiNINA_Generic)
 3. Add support to ESP32 and ESP8266 boards using native ESP WiFi
 4. Add support to Generic boards, such as **MKR WiFi1010**, using [WiFi101 Library](https://github.com/arduino-libraries/WiFi101)
 5. Add WiFi-related examples. 
 6. Modify hostname from easily-duplicated `arduino` to board-related hostname to fix issue caused by duplicated hostname, such as [mDNS stops working after two minutes #5](#5)
 7. Verify issue [**mDNS stops working after two minutes** #5](#5) is fixed, using Nano_RP2040_Connect, WiFiNINA FW 1.4.8 and [WiFiNINA_Generic Library](https://github.com/khoih-prog/WiFiNINA_Generic)
 8. Change License from `MIT` to [GPLv3](https://github.com/khoih-prog/MDNS_Generic/blob/master/LICENSE)
