v1.8.0 to add support to ESP8266 using W5x00

### Releases v1.8.0 1. Add support to ESP8266 using W5x00 with [lwIP_w5100](https://github.com/esp8266/Arduino/tree/master/libraries/lwIP_w5100) or [lwIP_w5500](https://github.com/esp8266/Arduino/tree/master/libraries/lwIP_w5500) library 2. Add example [AsyncHTTPRequest_ESP8266_Ethernet](https://github.com/khoih-prog/AsyncHTTPRequest_Generic/tree/master/examples/AsyncHTTPRequest_ESP8266_Ethernet) to demo the new feature. 3. Update `Packages' Patches`

+ *  Udp.cpp: Library to send/receive UDP packets.
+ *
+ * NOTE: UDP is fast, but has some important limitations (thanks to Warren Gray for mentioning these)
+ * 1) UDP does not guarantee the order in which assembled UDP packets are received. This
+ * might not happen often in practice, but in larger network topologies, a UDP
+ * packet can be received out of sequence.
+ * 2) UDP does not guard against lost packets - so packets *can* disappear without the sender being
+ * aware of it. Again, this may not be a concern in practice on small local networks.
+ * For more information, see http://www.cafeaulait.org/course/week12/35.html

 ## Changelog

+### Releases v1.8.0
+
+1. Add support to ESP8266 using W5x00 with [lwIP_w5100](https://github.com/esp8266/Arduino/tree/master/libraries/lwIP_w5100) or [lwIP_w5500](https://github.com/esp8266/Arduino/tree/master/libraries/lwIP_w5500) library
+2. Add example [AsyncHTTPRequest_ESP8266_Ethernet](https://github.com/khoih-prog/AsyncHTTPRequest_Generic/tree/master/examples/AsyncHTTPRequest_ESP8266_Ethernet) to demo the new feature.
+3. Update `Packages' Patches`
+
+### Releases v1.7.1
+
+1. Add example [AsyncHTTPRequest_ESP_Multi](https://github.com/khoih-prog/AsyncHTTPRequest_Generic/tree/master/examples/AsyncHTTPRequest_ESP_Multi) to demo connection to multiple addresses.
+2. Update `Packages' Patches`
+
+### Releases v1.7.0
+
+1. Add support to new `ESP32-S3` 
+2. Add `LittleFS` support to `ESP32-C3`
+3. Use ESP32-core's LittleFS library instead of Lorol's LITTLEFS library for v2.0.0+
+
+### Releases v1.6.0
+
+1. Reduce the breaking effect of v1.5.0 by enabling compatibility with old code to include only `AsyncHTTPRequest_Generic.h`
+2. Update `Packages' Patches`
+
 ### Releases v1.5.0

 1. Fix `multiple-definitions` linker error and weird bug related to `src_cpp`. Check [Different behaviour using the src_cpp or src_h lib #80](https://github.com/khoih-prog/ESPAsync_WiFiManager/discussions/80)

+//************************************************************************************************************
+//
+// There are scores of ways to use AsyncHTTPRequest.  The important thing to keep in mind is that
+// it is asynchronous and just like in JavaScript, everything is event driven.  You will have some
+// reason to initiate an asynchronous HTTP request in your program, but then sending the request
+// headers and payload, gathering the response headers and any payload, and processing
+// of that response, can (and probably should) all be done asynchronously.
+//
+// In this example, a Ticker function is setup to fire every 300 seconds to initiate a request.
+// Everything is handled in AsyncHTTPRequest without blocking.
+// The callback onReadyStateChange is made progressively and like most JS scripts, we look for
+// readyState == 4 (complete) here.  At that time the response is retrieved and printed.
+//
+// Note that there is no code in loop().  A code entered into loop would run oblivious to
+// the ongoing HTTP requests.  The Ticker could be removed and periodic calls to sendRequest()
+// could be made in loop(), resulting in the same asynchronous handling.
+//
+// For demo purposes, debug is turned on for handling of the first request.  These are the
+// events that are being handled in AsyncHTTPRequest.  They all begin with Debug(nnn) where
+// nnn is the elapsed time in milliseconds since the transaction was started.
