 - [DallasTemperature](https://github.com/milesburton/Arduino-Temperature-Control-Library.git)
 - [DHT-sensor-library](https://github.com/adafruit/DHT-sensor-library) - Arduino library for the DHT11/DHT22 temperature and humidity sensors. Download latest v1.1.1 library and no changes are necessary.  Older versions should initialize DHT as follows: `DHT dht(DHTPIN, DHTTYPE, 15)`
 - [NeoPixel](https://github.com/adafruit/Adafruit_NeoPixel) - Adafruit's NeoPixel library, now with support for the ESP8266 (use version 1.0.2 or higher from Arduino's library manager).
-- [NeoPixelBus](https://github.com/Makuna/NeoPixelBus) - Arduino NeoPixel library compatible with ESP8266. Use the "NeoPixelAnimator" branch for ESP8266 to get HSL color support and more.
+- [NeoPixelBus](https://github.com/Makuna/NeoPixelBus) - Arduino NeoPixel library compatible with ESP8266. Use the "DmaDriven" or "UartDriven" branches for ESP8266. Includes HSL color support and more.
 - [PubSubClient](https://github.com/Imroy/pubsubclient) - MQTT library by @Imroy.
 - [RTC](https://github.com/Makuna/Rtc) - Arduino Library for Ds1307 & Ds3231 compatible with ESP8266.
 - [Souliss, Smart Home](https://github.com/souliss/souliss) - Framework for Smart Home based on Arduino, Android and openHAB.
 - [ST7735](https://github.com/nzmichaelh/Adafruit-ST7735-Library) - Adafruit's ST7735 library modified to be compatible with ESP8266.  Just make sure to modify the pins in the examples as they are still AVR specific.
+- [Task](https://github.com/Makuna/Task) - Arduino Nonpreemptive multitasking library.  While similiar to the included Ticker library in the functionality provided, this library was meant for cross Arduino compatibility.
 - [UTFT-ESP8266](https://github.com/gnulabis/UTFT-ESP8266) - UTFT display library with support for ESP8266. Only serial interface (SPI) displays are supported for now (no 8-bit parallel mode, etc). Also includes support for the hardware SPI controller of the ESP8266.
 - [WiFiManager](https://github.com/tzapu/WiFiManager) - WiFi Connection manager with web captive portal. If it can't connect, it starts AP mode and a configuration portal so you can choose and enter WiFi credentials.
