Release Notes
ejabberd 3.0.0
ejabberd 3.0.0 is the first release in the brand new 3.x.x branch,
and includes several minor bugfixes and a few improvements.
Read more details about the changes in:
http://redir.process-one.net/ejabberd-3.0.0
Download the source code and installers from:
http://www.process-one.net/en/ejabberd/
ejabberd 3.0.0 includes three major changes:
* exmpp is now extensively used in ejabberd for parsing stanzas, and many more.
* gen_storage (abbreviated GS) provides a database abstraction layer,
which supports storage in Mnesia and in ODBC databases.
Several ejabberd modules use GS, like mod_roster and ejabberd_auth_storage.
The schema of the tables stored by those modules have changed.
ejabberd automatically creates mnesia and ODBC tables,
and migrates them from a previous ejabberd version.
* Massive Hosting (abbreviated MH) is preliminary implemented in ejabberd,
but it is still incomplete, untested and undocumented.
