This release contains major changes related to better compatibility w…

…ith Arduino.

- Arduino compatibility improvements (#1213).
- Library code for some Arduino libraries comes directly from their source repositories (Adafruit_ST7735, Adafruit_SSD1306).
- Added dynamic recalculation of image offsets to prevent rom overlapping (#1208).
- Added Wi-Fi Protected Setup (WPS) support (#1199).
- Ram savings in axTLS (#1255).
- Simplified and improved Http Client and Http Server stream handling (#1247).
- Fixed Memory Leak in Mqtt (#1273).
- Updated Spiffs code to version 0.3.7 + fixes (##1246).

And much more. All merged PRs in this release can be seen from [here](https://github.com/SmingHub/Sming/milestone/12?closed=1)

- Changed the order of Wire.begin and Wire.pins parameters to match the Arduino order (#1193).

For a complete list of changes run the following command:

```
git log 3.3.0..3.4.0
```

Thanks to everyone who helped us make this release happen.

 - Custom LWIP: (default: ON) By default we are using custom compiled LWIP stack instead of the binary one provided from Espressif. This is increasing the free memory and decreasing the space on the flash. All espconn_* functions are turned off by default. If your application requires the use of some of the espconn_* functions then add the ENABLE_ESPCONN=1 directive. See `Makefile-user.mk` from the [Basic_SmartConfig](https://github.com/SmingHub/Sming/blob/develop/samples/Basic_SmartConfig/Makefile-user.mk#L41) application for examples. If you would like to use the binary LWIP then you should turn off the custom LWIP compilation by providing `ENABLE_CUSTOM_LWIP=0`.
 - SSL: (default: OFF) The SSL support is not built-in by default to conserve resources. If you want to enable it then take a look at the [Readme](https://github.com/SmingHub/Sming/blob/develop/samples/Basic_Ssl/README.md) in the Basic_Ssl samples.
 - Custom PWM: (default: ON) If you don't want to use the [open PWM implementation](https://github.com/StefanBruens/ESP8266_new_pwm) then compile your application with `ENABLE_CUSTOM_PWM=0`. There is no need to recompile the Sming library.
+- WPS: (default: OFF) The WPS support (Wi-Fi Protected Setup) is not activated by default to preserve resources. To enable WPS, use the switch ENABLE_WPS=1 for compiling Sming.
 - Custom serial baud rate: (default: OFF) The default serial baud rate is 115200. If you want to change it to a higher baud rate you can recompile Sming and your application changing the `COM_SPEED_SERIAL` directive. For example `COM_SPEED_SERIAL=921600`.
 - Custom heap allocation: (default: OFF) If your application is experiencing heap fragmentation then you can try the [umm_malloc](https://github.com/rhempel/umm_malloc) heap allocation. To enable it compile Sming with `ENABLE_CUSTOM_HEAP=1`. In order to use it in your sample/application make sure to compile the sample with `ENABLE_CUSTOM_HEAP=1`. **Do not enable custom heap allocation and -mforce-l32 compiler flag together**.
 - Debug information log level and format: There are four debug levels: debug=3, info=2, warn=1, error=0. Using `DEBUG_VERBOSE_LEVEL` you can set the desired level (0-3). For example `DEBUG_VERBOSE_LEVEL=2` will show only info messages and above. Another make directive is `DEBUG_PRINT_FILENAME_AND_LINE=1` which enables printing the filename and line number of every debug line. This will require extra space on flash. Note: you can compile the Sming library with a set of debug directives and your project with another settings, this way you can control debugging separately for Sming and your application code.
