This first alpha includes three major changes compared to ejabberd 2.1.5: exmpp library is used, gen_storage for a database abstraction layer, and Massive Hosting which isn't yet usable.
Many tables have changed both in Mnesia and MySQL/PgSQL/ODBC. Fortunately, now ejabberd is able to create tables, update the tables and reformat their content in Mnesia and also in external databases. Or at least it should do.
Please note that the database schema used in this preliminary release is not yet definitive, and it will probably change in the next alpha and beta releases.
When compiling the source code, it is necessary to install exmpp.
Recommendation: try this alpha release far away from a production server. Try it with an empty database, or with a copy of your existing database. Please report bugs you find, including logged errors if any, in the usual
or in the ejabberd mailing list.
