Recent changes include....
Recent changes include:
Encrypted server-to-server connections
Server-to-server Encryption for Enhanced Security
- Support for STARTTLS+SASL EXTERNAL for Server-to-Server connections.
- STARTTLS+Dialback has been implemented for Server-to-Server (s2s)
connections. Those options are handled with two new config file options
(s2s_use_starttls and s2s_certfile). See ejabberd.cfg.example for usage
examples.
- DNSName certificate field and DNS name matching are supported.
- Per virtual host certificate can be defined.
- 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 program that convert an installation from Erlang Mnesia
database to an ODBC relational database.
- 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
- Native postgreSQL support has been added: You can now use a PostgreSQL
database without the need to go through the ODBC driver.
- Native PostgreSQL support gives you a better performance when you use
PostgreSQL.
Shared roster
Shared Roster groups
- Shared roster support have been improved: You can specify all users in a
virtual host for addition in a group.
- 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
Web Interface
- The Web interface internal code has been modified for better integration
and compliance with J-EAI.
- The Web interface is now compliant to XHTML 1.0 Transitional.
- Several bugs have been fixed.
- 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 with the compile time option. You
- 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

sending <presence type='subscribed'/> stanza to user. This option is
needed for JIT ICQ transport.
Warning: By using this option, ejabberd is not fully XMPP compliant.
script. (./configure --enable-roster-gateway-workaround)
This option allows transports to add items with subscription "to" in the
roster by sending <presence type='subscribed'/> stanza to user. This option
is only needed for JIT ICQ transport.
Warning: by enabling this option, ejabberd will not be fully XMPP compliant
anymore.

Migration
Migration Notes
- Before any migration, ejabberd system and database must be properly
backed-up.
- System migrating from a previous ODBC based install will need to change
their 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;
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;
