 # **node-poweredup** - A Javascript module to interface with LEGO Powered Up components.
 
+### Announcements
+
+*Important*: v6.0.0 is a complete re-architecting of this library. Improvements include proper device and mode support through an external Device object, correct handling of firmware features, and promise-based functionality for interfacing with device attachments. Although many new features were added, existing code will almost surely break upon upgrade.

 ### Introduction
 
-LEGO Powered Up is the successor to Power Functions, the system for adding electronics to LEGO models. Powered Up is a collection of ranges - starting with LEGO WeDo 2.0 released in 2016, LEGO Boost released in 2017, LEGO Powered Up released in 2018, and LEGO Technic CONTROL+ released in 2019. It also includes the 2018 Duplo App-Controlled Train sets.

It also includes the 2018 Duplo App-Controlled Train sets.
 
 This library allows communication and control of Powered Up devices and peripherals via Javascript, both from Node.js and from the browser using Web Bluetooth.
 
 ### Node.js Installation
 
-Node.js v8.0 required.
+Node.js v8.0+ required.
 
 ```javascript
 npm install node-poweredup --save
 ```
 
 node-poweredup uses the Noble BLE library by Sandeep Mistry. On macOS everything should function out of the box. On Linux and Windows there are [certain dependencies which may need installed first](https://github.com/noble/noble#prerequisites).
 
-Note: node-poweredup has been tested on macOS 10.13 and Debian/Raspbian on the Raspberry Pi 3 Model B.
