Update README.md

Alpine linux does not have -n option in copy binary.
To avoid a problem on configure, I replaced the command with an "if".

+# Change Log
+
+## 1.1.3 (2018-10-23)
+
+- New config option (MAX_COMMIT_ITERATIONS) to avoid max commit iterations
+faults for more complex scripts.
+- Support base64 and hexBinary parameter types.
+- Strict parsing of number values in queries (e.g. "123abc" no longer accepted
+as 123).
+- Mixing $ne and $not operators is not allowed. Now it throws an error instead
+of returning incorrect results.
+- When a task expires, any associated fault is also deleted.
+- API now accepts 'timeout' argument when posting a task.
+- A number of stability fixes.
+
+## 1.1.2 (2018-02-24)
+
+- A large number of bug fixes as well as stability and performance improvements.
+- Three security vulnerabilities disclosed by Maximilian Hils have been patched.
+- New config option UDP_CONNECTION_REQUEST_PORT to specify binding port for UDP
+connection requests.
+- New config option DATETIME_MILLISECONDS to strip milliseconds from dateTime
+values.
+- New config option BOOLEAN_LITERAL to use 1/0 or true/false for boolean values.
+- Parameter values that cannot be parsed according to the reported type now show
+a warning message.
+- Virtual parameter scripts now use the variable 'args' instead of the special
+'TIMESTAMPS' and 'VALUES' variables. The content of the args array is: {declare
+timestamps}, {declare values}, {current timestamps}, {current values}.
+- Virtual parameter value types are now inferred from the JavaScript type if the
+returned value attribute is not a value-type pair.
+- Show a fault when a virtual parameter script doesn't return the required
+attributes.
+- Redis is now optional (and disabled by default), reducing the complexity of
+scalable deployments.
+- Better detection of cyclical presets resulting in fewer faults for complex
+provisioning scripts.
+- Math.random() is now deterministic on per-device basis. A function has been
+added to allow specifying a seed value (e.g. Math.random.seed(Date.now())).
+- Overload spikes are now handled gracefully by refusing to accept new sessions
+temporarily when under abnormal load.
+- Added log messages for session timeouts, connection drops, and XML parsing
+errors.
+- Date.now() now takes an optional argument to specify "time steps" (in
+milliseconds). This can be used to ensure a group of parameters are all
+refreshed at the same time intervals.
+- Only the non-default configuration options are now logged at process start.
+- Faults caused by errors from extensions now show a cleaner stack trace.
+- Exit main process if there are too many worker crashes (e.g. when DB is down).
+- Updated dependencies and included a lockfile to ensure installations get the
+exact dependencies it was tested against.
+
+## 1.1.1 (2017-03-23)
+
+- Avoid crashing when connection request credentials are missing.
+- Show a warning instead of crashing when failing to parse parameter values
+according to the expected value type.
+- Add missing "Registered" event.
+- Fix bug where in certain cases many more instances than declared are created.
+- Fix parameter discovery bug when declared path timestamp is 1 or is not set.
+- Fix preset precondition failing when testing against datetime parameters and
+certain other parameters like \_deviceId.\_ProductClass.
+
+## 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/genieacs/genieacs-gui.
 
 ## Features
 
-* **Massively concurrent**: Can handle hundreds of thousands of connected devices on a single server even with low inform interval.
+- **Battle-tested at scale**: Can scale to manage hundreds of thousands and
-* **Preset-based configuration**: Define sets of configurations that devices will pick up and apply as needed based on given preconditions.
+potentially millions of devices
-* **Tagging**: Use tags to group devices for more manageable presets.
+- **Powerful provisioning system**: Scriptable configuration to handle complex
-* **Searching**: Query for devices on any parameter (supports all common operators including regular expressions).
+device provisioning scenarios and other automated operations such as firmware
-* **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).
+upgrade
-* **Extensive API**: A simple yet rich HTTP-based API allows easy integration with other system.

-## 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/) and [MongoDB](http://www.mongodb.org/).
+Refer to their corresponding documentation for installation instructions. The
+supported versions are:
+
+- Node.js: 6.x and 8.x (8.x recommended)
+- MongoDB: 2.6 through 3.4
+
+Install build tools and libxml2 development files from your system's package
+manager.
+
+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:
 
-    cd /opt
+    git clone https://github.com/genieacs/genieacs.git

+    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:
+Before proceeding, find and review the file "config.json" in "config" directory
+where GenieACS is downloaded.
