Release Notes: This release brings full support for IPv6 throughout the server, the top feature request since 0.8. It also makes a number of security enhancements, including support for server-to-server authentication using certificates instead of traditional DNS-based authentication ('dialback'). Other improvements include a new HTTP subsystem supporting virtual hosts and fully reloadable modules, pubsub support (XEP-0060), and more.
Release Notes: This release adds support for libevent (epoll, kqueue, etc.) to enable handling of a large number of connections. Also new is support for Cyrus SASL authentication, allowing authentication against LDAP, PAM, SQL, and others, in addition to allowing GSSAPI/Kerberos. Support for SASL SCRAM allows for more secure logins, and server-to-server compression allows for bandwidth savings.
Release Notes: This is a new major release. It brings many internal changes and a bunch of new modules. Thanks to refactoring of the core routing code, extensibility was improved and performance is greater than previous releases. New plugins were added for "shared roster"/groups support, sending a notification to admins and a greeting to new users when they register, and sending announcements to all online users. The telnet console has been made much more powerful, and there is now support for requiring the encryption of XMPP client connections.
