+# Change Log
+
+## 1.1.0 (2017-03-10)
+
+- Provisions enable implementing dynamic device configuration or complex device
+provisioning work flow using arbitrary scripts.
+- Virtual parameters are user-defined parameters whose values are evaluated from
+a custom script.
+- Extensions are sandboxed Node.js scripts that are accessible from provision
+and virtual parameter scripts to facilitate integration with external entities.
+- Support for UDP/STUN based connection requests for reaching devices behind
+NAT (TR-069 Annex G).
+- Presets can now be scheduled using a cron-like expression.
+- Presets can now be tied to specific device events (e.g. boot).
+- Presets precondition queries no longer support "$or" or other MongoDB logical
+operators.
+- Faults are no longer a part of tasks but are now first class objects.
+- Presets are now assigned to channels. A fault in one channel only blocks
+presets in that channel.
+- New API CRUD functions for provisions, virtual parameters, and faults.
+- New config options for XML output.
+- API responses now include "GenieACS-Version" header.
+- Graceful shutdown when receiving SIGINT and SIGTERM events.
+- Support SSL intermediate certificate chains.
+- Supported Node.js versions are 6.x and 7.x.
+- Supported MongoDB versions are 2.6 through 3.4.
+- Expect performance differences due to major under the hood changes. Some
+operations are faster and some are slower. Overall performance is improved.
+- GenieACS will no longer fetch the entire device data model upon first contact
+but will instead only fetch the parameters it needs to fulfill the presets.
+- Logs have been overhauled and split into two streams: process log (stderr) and
+access log (stdout). Also added config options to dump logs to files rather than
+standard streams.
+- Connection request authentication credentials are picked up from the device
+data model if available. config/auth.js is still supported as a fallback and now
+supports an optional callback argument.
+- Custom commands have been removed. Use virtual parameters and/or extensions.
+- Aliases and value normalizers (config/parameters.json) have been removed. Use
+virtual parameters.
+- The API /devices/<device_id>/preset has been removed.
+- Rarely used RequestDownload method no longer supported.
+- The TR-069 client simulator has moved to its own repo at
+https://github.com/zaidka/genieacs-sim

 # GenieACS
 
-GenieACS is a *blazing fast* TR-069 auto configuration server (ACS) built with Node.js, Redis, and MongoDB. It's technology neutral and configurable to fit any service provider needs. This is the core back end component. Official front end GUI is available at https://github.com/zaidka/genieacs-gui.
+GenieACS is a fast and lightweight TR-069 auto configuration server (ACS). This
+is the core back end component. A GUI front end is available at
+https://github.com/zaidka/genieacs-gui.
 
 ## Features
 
-* **Massively concurrent**: Can handle hundreds of thousands of connected devices on a single server even with low inform interval.
-* **Preset-based configuration**: Define sets of configurations that devices will pick up and apply as needed based on given preconditions.
-* **Tagging**: Use tags to group devices for more manageable presets.
-* **Searching**: Query for devices on any parameter (supports all common operators including regular expressions).
-* **Parameter aliasing**: Define aliases to unify parameter paths from different types of devices. Aliases behave like normal parameters (i.e. can be queried or modified).
-* **Extensive API**: A simple yet rich HTTP-based API allows easy integration with other system.
+- **Battle-tested at scale**: Can scale to manage hundreds of thousands and
+potentially millions of devices
+- **Powerful provisioning system**: Scriptable configuration to handle complex
+device provisioning scenarios and other automated operations such as firmware
+upgrade
+- **Extensive API**: A rich HTTP-based API allows easy integration with other
+systems
 
-## Getting started
+## Quick Start
 
-Install [Node.js](http://nodejs.org/), [Redis](http://redis.io/), and [MongoDB](http://www.mongodb.org/). Refer to the corresponding documentation for installation guides. Then use NPM to install GenieACS by typing:
+Install [Node.js](http://nodejs.org/), [Redis](http://redis.io/), and

+installation guides. Supported versions are:
+
+- Node.js: 6.x and 7.x (7.x recommended)
+- Redis: 2.4 through 3.2
+- MongoDB: 2.6 through 3.4
+
+Then install GenieACS using NPM:
 
     npm install -g genieacs
 
-You may need to modify the configuration files under "config" directory (in /lib/node_modules/genieacs/config) depending on your setup.
+Alternatively, you can install from source by cloning the git repository:
 
-Alternatively, you can use git to get the latest development version (not recommended for production use):
-
-    cd /opt
     git clone https://github.com/zaidka/genieacs.git
     cd genieacs
+    git checkout $(git tag -l v1.1.* --sort=-v:refname | head -n 1)
     npm install
-    npm run configure
     npm run compile
 
-Finally, run the following in GNU Screen session or something similar:
+Finally, run the following (from bin directory if installing from source):
