 ESP8266 WiFi Connection manager with fallback web configuration portal
 
+[![Build Status](https://travis-ci.org/tzapu/WiFiManager.svg?branch=master)](https://travis-ci.org/tzapu/WiFiManager)

 The configuration portal is of the captive variety, so on various devices it will present the configuration dialogue as soon as you connect to the created access point.

 You can use WiFiManager to collect more parameters than just SSID and password.
 This could be helpful for configuring stuff like MQTT host and port, [blynk](http://www.blynk.cc) or [emoncms](http://emoncms.org) tokens, just to name a few.

+#### Custom IP Configuration
+You can set a custom IP for both AP (access point, config mode) and STA (station mode, client mode, normal project state)
 
-### Custom Access Point IP Configuration
+##### Custom Access Point IP Configuration
 This will set your captive portal to a specific IP should you need/want such a feature. Add the following snippet before `autoConnect()`
 ```cpp
 //set custom ip for portal
 wifiManager.setAPStaticIPConfig(IPAddress(10,0,1,1), IPAddress(10,0,1,1), IPAddress(255,255,255,0));
 ```
 
-### Custom Station (client) Static IP Configuration
+##### Custom Station (client) Static IP Configuration
 This will make use the specified IP configuration instead of using DHCP in station mode.
 ```cpp
 wifiManager.setSTAStaticIPConfig(IPAddress(192,168,0,99), IPAddress(192,168,0,1), IPAddress(255,255,255,0));
 ```
 There are a couple of examples in the examples folder that show you how to set a static IP and even how to configure it through the web configuration portal.
 
+#### Custom HTML, CSS, Javascript
+There are various ways in which you can inject custom HTML, CSS or Javascript into the configuration portal.
+The options are:
+- inject custom head element
+You can use this to any html bit to the head of the configuration portal. If you add a `<style>` element, bare in mind it overwrites the included css, not replaces.
+```cpp
+wifiManager.setCustomHeadElement("<style>html{filter: invert(100%); -webkit-filter: invert(100%);}</style>");
+```
+- inject a custom bit of html in the configuration form
+```cpp
+WiFiManagerParameter custom_text("<p>This is just a text paragraph</p>");
+wifiManager.addParameter(&custom_text);
+```
+- inject a custom bit of html in a configuration form element
+Just add the bit you want added as the last parameter to the custom parameter constructor.
+```cpp
+WiFiManagerParameter custom_mqtt_server("server", "mqtt server", "iot.eclipse", 40, " readonly");
+```
+
 #### Filter Networks

+- You can also remove or show duplicate networks (default is remove).

 ## Troubleshooting
 If you get compilation errors, more often than not, you may need to install a newer version of the ESP8266 core for Arduino.
 
-I am trying to keep releases working with release versions of the core, so they can be installed through boards manager, but if you checkout the latest version directly from github, sometimes, the library will only work if you update the ESP8266 core to the latest version because I am using some newly added function.
+Changes added on 0.8 should make the latest trunk work without compilation errors. Tested down to ESP8266 core 2.0.0. **Please update to version 0.8**

 If you connect to the created configuration Access Point but the configuration portal does not show up, just open a browser and type in the IP of the web portal, by default `192.168.4.1`.
 
+If trying to connect ends up in an endless loop, try to add `setConnectTimeout(60)` before `autoConnect();`. The parameter is timeout to try connecting in seconds.
 
 ## Releases
-#### 0.6
+#### 0.12
+- removed 204 header response
+- fixed incompatibility with other libs using isnan and other std:: functions without namespace
+
+##### 0.11
+- a lot more reliable reconnecting to networks
+- custom html in custom parameters (for read only params)
+- custom html in custom parameter form (like labels)
+- custom head element (like custom css)
+- sort networks based on signal quality
+- remove duplicate networks
+
+##### 0.10
+- some css changes
+- bug fixes and speed improvements
+- added an alternative to waitForConnectResult() for debugging
+- changed `setTimeout(seconds)` to `setConfigPortalTimeout(seconds)`
+
+##### 0.9
+ - fixed support for encoded characters in ssid/pass
+
+##### 0.8
+ - made it compile on older versions of ESP8266 core as well, tested down to 2.0.0
+ - added simple example for Custom IP
+
+##### 0.7
+ - added static IP in station mode
+ - added example of persisting custom IP to FS config.json
+ - more option on portal homepage
+ - added on PlatformIO
+
+##### 0.6
  - custom parameters
  - prettier
  - on demand config portal
