Release Note ejabberd 1.0.0 - 14 Dec 2005

This document describes the main changes in ejabberd 1.0.0. Unique in this version is the compliancy with the XMPP (eXtensible Messaging and Presence Protocol) standard. ejabberd is the first Open Source Jabber server claiming to fully comply to the XMPP standard.

ejabberd can be downloaded from ejabberd download page.

Detailed information can be found in the ejabberd Feature Sheet and User Guide which are available on the Process-one ejabberd documentation page.

Server-to-server Encryption for Enhanced Security

• Support for STARTTLS and SASL EXTERNAL to secure server-to-server traffic has been added.
• Also, STARTTLS and Dialback has been implemented for server-to-server (s2s) connections. Detailed information about these new features can be found on http://ejabberd.jabber.ru/s2s-encryption
• commonName and dNSName fields matching were introduced to ease the process of retrieving certificates.
• Different certificates can be defined for each virtual host.

ODBC Support

• ODBC support has been improved to allow production use of ejabberd with relational databases.
• Support for vCard storage in ODBC has been added.
• ejd2odbc.erl is a tool to convert an installation from Erlang's database Mnesia to an ODBC compatible relational database.

Native PostgreSQL Support

• Native PostgreSQL support gives you a better performance when you use PostgreSQL.

Shared Roster groups

• Shared Roster groups support has been enhanced. New is the ability to add all registered users to everyone's roster. Detailed information about this new feature can be found on http://ejabberd.jabber.ru/shared-roster-all

Web Interface

• The web interface internal code has been modified for better integration and compliancy with J-EAI, an ejabberd-based Enterprise Application Integration platform.
• More XHTML 1.0 Transitional compliancy work was done.

Transports

A transport workaround can be enabled during compilation. To do this, you can pass the --enable-roster-gateway-workaround option to the configure script. For example:

./configure --enable-roster-gateway-workaround

This option allows transports to add items with subscription "to" in the roster by sending {{}} stanza to user. This option is only needed for JIT ICQ transport.

By enabling this option, ejabberd is not fully XMPP compliant anymore.

Migration Notes

• Before any migration, ejabberd system and database must be properly backed up.
• When upgrading an ODBC-based installation, you will need to change the relational database schema. The following SQL commands must be run on the database:

  CREATE SEQUENCE spool_seq_seq;
  ALTER TABLE spool ADD COLUMN seq integer;
  ALTER TABLE spool ALTER COLUMN seq SET DEFAULT
           nextval('spool_seq_seq');
  UPDATE spool SET seq = DEFAULT;
  ALTER TABLE spool ALTER COLUMN seq SET NOT NULL;
