ejabberd 15.06 has been released

New features

The focus of this release is archiving and easier configuration.

Message Archive Management support

Message Archive Management (aka MAM, defined in XEP-313) is now the de facto standard for message archiving in XMPP world.

ejabberd now comes with its own full feature message archiving implementation:
– It support both version 0.2 and the more recent version 0.3 of the protocol.
– It support Mnesia internal storage and relational database backend (aka odbc, but actually use native drivers).

To enable it, simply add mod_mam in ejabberd modules configuration section, telling it to use your configured relational database.

    db_type: odbc

Please, also check the sql directory to find about the table to add to your relational database. MAM relational storage is supported for MySQL, Postgres and SQLite.

Configuration checking on launch

ejabberd is sometime difficult to configure, especially when you want to define complex setup. After having changed the configuration file to support YAML format, we now introduce a new feature to help you get your configuration right.

On ejabberd launch, you will now see report about possible misconfiguration, with explicit error message.

For example, suppose there is a typo on the registration_timeout option, you’ll get the following error in the log file:

16:15:20.487 [error] unknown option 'registrtion_timeout' will be likely ignored

This can be of great help when trying to understand why an option is not taken into account.

Windows installer

The Microsoft Windows installer is back, as a beta version. Windows is not a good platform to run a production ejabberd server, for various reasons. However, many users are developing on Windows or want to try ejabberd from their Windows Desktop. Building ejabberd on Windows is very complex, so we decided to finally update our packaging to bring latest ejabberd to Windows users. The installer is 64 bits only, it supports Windows 7 and Windows 8.

The installer is still considered experimental. For example, we did not yet sign the installer with Windows developer account to become a trusted developer. This may come depending on the feedback we get regarding our Windows version.

Please, send us your feedback and contributions!

RPM and DEB packages

We have been providing for years a binary installer that includes everything you need to run ejabberd. It includes all the dependencies and a minimal version of Erlang, independently from the one installed on your system.

We now provide the same binary packaging as RPM and DEB for 64bit Linux. This is generated from the same source so it includes its own minimal version of Erlang and doesn’t have any dependencies on other packages. This is still a work in progress, it means that your feedback is welcome. The packages can be downloaded from ProcessOne ejabberd download page.

We hope that this is another step in making ejabberd simpler to deal with and even more ubiquitous. It should also help you stay up to date and always be able to run the latest ejabberd version.


We now have an installer for contributed modules since ejabberd 15.04. In that new release, we’ve improved automatic compilation of external modules, it’s now more robust and able to handle more complex modules.

Documentation now includes supported protocols with versions by parsing directly modules source code.

I think there is a typo in

I think there is a typo in Message Archive Management support section:

    dbtype: odbc # should be db_type

You're right. It's fixed now.

You're right. It's fixed now. Thanks!

I am looking to build a chat

I am looking to build a chat server using EJABBERD and XMPP but don't know how to start. Can anyone share with me good docs/tutorials to follow as a beginner.

Also, does ejabberd include a database for storing chat messages, if so please provide some help as to where to begin.
