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.
|
||||
|
||||

|
||||
|
||||
|
||||
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,
|
||||
and ejabberd migrates automatically your mnesia and ODBC
|
||||
tables from previous ejabberd releases.
|
||||
|
||||
* Massive Hosting (abbreviated MH) is preliminary implemented in ejabberd,
|
||||
but it is still incomplete, untested and undocumented.
|
||||
|
||||
|
||||
