Version 2.0 (West of West Lake) Version 2.0 (West of West Lake)
------------------------------- -------------------------------
*Release Date: 2016-08-29* *Release Date: 2016-08-30*
Improve the design of PubSub and Router: *Release Name: West of West Lake*
.. images:: _static/images/publish.png .. NOTE:: Dont' upgrade 1.x production deployment to 2.0-beta1 release.
EMQ - Shortened Project Name
----------------------------
Adopt a shortened projectname: EMQ(Erlang/Enterprise/Elastic MQTT Broker)，E means Erlang/OTP, Enterprise and Elastic.
Improve the Release Management
------------------------------
In order to iterate the project fast, we will adopt a new release management strategy since 2.0. There will be two or three 'Preview Release' named beta1, beta2 or beta3, and then one or two 'Release Candidate' named rc1, rc2 before a Major version is production ready.
Seperate Rel from Application
-----------------------------
We split the emqttd 1.x project into two projects since 2.0-beta1 release to resolve the plugins' dependency issue.
A new project named `emqttd-relx`_ is created and responsible for buiding the emqttd application and the plugins::
git clone https://github.com/emqtt/emqttd-relx.git
cd emqttd-relx && make
cd _rel/emqttd && ./bin/emqttd console
erlang.mk and relx
------------------
The rebar which is used in 1.x release is replaced by `erlang.mk`_ and `relx`_ tools since 2.0-beta1 release.
You can check the 'Makefile' and 'relx.config' in the release project of the borker: `emqttd-relx`_ .
Improve Git Branches Management
-------------------------------

+------------+-------------------------------------------+
| emq30 | 3.x Development Branch |
+------------+-------------------------------------------+
| issue#{id} | BugFix Branch |
+------------+-------------------------------------------+
New Config Syntax
-----------------
Since 2.0-beta1 release the configuration file of the broker and plugins adopt a new syntax like rebar.config or relx.config:
etc/emqttd.conf for example::
%% Max ClientId Length Allowed.
{mqtt_max_clientid_len, 512}.
%% Max Packet Size Allowed, 64K by default.
{mqtt_max_packet_size, 65536}.
%% Client Idle Timeout.
{mqtt_client_idle_timeout, 30}. % Second
MQTT-SN Protocol Plugin
-----------------------
The MQTT-SN Protocol Plugin `emqttd_sn`_ has been ready in 2.0-beta1 release. The default UDP port of MQTT-SN is 1884.
Load the plugin::
./bin/emqttd_ctl plugins load emqttd_sn
Improve Design of PubSub and Router
-----------------------------------
.. image:: _static/images/publish.png
Improve Plugin Management
-------------------------
The plugin of EMQ 2.0 broker is a normal erlang application which depends on and extends 'emqttd'. User can create a standalone plugin application project, and add it to `emqttd-relx`_ Makefiel as a dependency.
All the plugins' config files will be copied to emqttd/etc/plugins/ folder when making emqttd brinary packages in `emqttd-relx`_ project::

▾ etc/

▾ plugins/
