Support for authentication and storage modules to integrate Prosody with 3rd-party databases, directories, and other systems. The first new storage plugin is for SQL databases and supports MySQL, PostgreSQL, and SQLite3. Also included is a migrator to move data between the file-based and SQL storage. Ad-hoc command support is now included by default to allow configuration and control of Prosody remotely from an XMPP client. Multi-user conferences now support members-only, invite-only, and password-protected rooms.
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.
Various bugfixes and minor enhancements were made. Important changes include disabling SSLv2 by default (since it is insecure) and fixing a bug which could cause invalid XML to be sent to clients. Some cases where data sent to a connection immediately before close could be lost were also fixed. The algorithm for choosing targets from SRV records was fixed. Stanzas sent over s2s connections are ensured to always have the correct namespace.
This release brings server-to-server encryption support and configurable per-vhost SSL certificates. Multi-user chat now allows multiple resources in different locations to share the same nickname in a chatroom, as well as admin controls such as kick and ban. Zlib stream compression for clients reduces bandwidth consumption (useful for mobile connections). New console commands allow adding/removing vhosts at runtime.
This is a bugfix release for the stable 0.5 branch. It contains several DNS-related fixes, resolving issues that could cause "stuck" s2s connections. It also fixes some compatibility issues with clients. It fixes a libidn-related crash on Vista and some other Windows versions.
