-Cross-platform: <TT>ejabberd</TT> runs under Microsoft Windows and Unix derived systems such as Linux, FreeBSD and NetBSD.</LI><LI CLASS="li-itemize">Distributed: You can run <TT>ejabberd</TT> on a cluster of machines and all of them will serve the same Jabber domain(s). When you need more capacity you can simply add a new cheap node to your cluster. Accordingly, you do not need to buy an expensive high-end machine to support tens of thousands concurrent users.</LI><LI CLASS="li-itemize">Fault-tolerant: You can deploy an <TT>ejabberd</TT> cluster so that all the information required for a properly working service will be replicated permanently on all nodes. This means that if one of the nodes crashes, the others will continue working without disruption. In addition, nodes also can be added or replaced &#X2018;on the fly&#X2019;.</LI><LI CLASS="li-itemize">Administrator Friendly: <TT>ejabberd</TT> is built on top of the Open Source Erlang.

+* These are the preliminary release notes of ejabberd 3.0.0.
+*
+* The download page for preliminary releases is:
+*   http://download.process-one.net/ejabberd/
+*
+*     WARNING!!!  PRELIMINARY DATABASE SCHEMA !!!
+* The database schema may change before ejabberd 3.0.0 is released,
+*   and no migration code will be developed for this preliminary schema.
+* The only supported migrations are
+*   from any ejabberd 0.9.0 ... 2.1.x to the final 3.0.0.
+* Don't use this preliminary ejabberd release for a production server.
+* You can test this release with a blank database or with a copy of your
+*   production database, but don't let your users connect to this copy
+*   because their changes may get lost when you upgrade to the final 3.0.0.

+                              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.
+  New option static_modules.
+
+
+This is a more detailed list of changes since ejabberd 2.1.x releases:
+
+* Requirements
+- Erlang/OTP R12B-5 or higher is required
+- exmpp 0.9.6 or higher is required, not optional
+- ESASL library is optional, for SASL GSSAPI authentication
+- Libexpat not required by ejabberd, it uses exmpp now (EJAB-1111)
+- GNU Iconv not required, because mod_irc isn't included anymore (EJAB-954)
+- Only database migration from ejabberd 0.9.0 up to 2.1.x is supported
+- ejabberd modules developed for previous releases need to be upgraded to exmpp
+
+* Configuration
+- New option clusterid
+- New option that can't be used yet: static_modules
+- ejabberd_auth_storage: new option auth_storage
+- mod_muc_log: option spam_prevention is now link_nofollow (EJAB-1141)
+- mod_roster: new access option (EJAB-72)
+- S2S: allow definition of local address for outgoing connections (EJAB-418)
+
+* Database
+- New gen_storage that provides a database storage abstraction layer (EJAB-1102)
+- mod_*_odbc are obsolete, use the normal ones with the option {backend, odbc}
+- New ejabberd_auth_storage that supports internal and odbc databases
+
+* XEP support
+- Removed support for the deprecated XEP-0018 Invisible Presence (EJAB-810)
+- Update http_bind to XEP-0124 1.10 and XEP-0206 1.3
+- mod_multicast: service for XEP-0033: Extended Stanza Addressing (EJAB-265)
+- New ejabberd router for multicast packets (XEP-0033) (EJAB-329)
+- ejabberd_c2s uses XEP-0033 if mod_multicast is enabled (EJAB-267)
+- mod_muc uses XEP-0033 if mod_multicast is enabled (EJAB-266)
+
+* Pubsub/PEP/Caps
+- Allow distinguish between leafs and items (EJAB-1027)
+- Enforce disco features results (EJAB-1033, EJAB-1228, EJAB-1238)
+- Enforce pubsub#presence_based_delivery (EJAB-1221)
+- Improve get_caps while still waiting for initial presence (EJAB-934)
+- Make nodetree_tree implicitly create parent node if required (EJAB-944)
+- Only use binary() instead of string() in Host and ServerHost (EJAB-1244)
+- Rename NodeId (pubsub_node.id) bindings to Nidx (EJAB-1000)
+- node_flat becomes default; it has the code instead of hometree (EJAB-1077)
+- pubsub#notify_sub node option (EJAB-1230)
+- pubsub#type node config and payload namespace (EJAB-1083)
+
+* Miscellanea
+- Bugfix handling Service Discovery to contacts (EJAB-1207)
+- Bugfix: external contacts were offline after unavailable presence (EJAB-943)
+- Don't offer SASL auth before doing TLS if TLS is required
+- Experimental support for GSSAPI auth, requires esasl library (EJAB-831)
+- Replaced the full ejabberd_zlib into a simple exmpp_compress interface (EJAB-991)
+- Use binaries instead of lists where possible (EJAB-17)
+- Webadmin: provide list of registered pids/ports
+- Windows ejabberdctl.cmd only handles up to 4 arguments (EJAB-1216)
+- ejabberdctl: when starting, check it isn't already running
