Citadel is an advanced messaging and collaboration system for groupware and BBS applications. Users can connect to Citadel using any telnet, WWW, or client software. Among the features supported are public and private message bases (rooms), electronic mail, real-time chat, paging, shared calendaring, address books, mailing lists, and more. Unlike other collaboration servers, Citadel provides its own data stores and is therefore extremely easy to install; you don't have to "bring your own" email and database because they're built in. The server is multithreaded and scalable. In addition, SMTP, IMAP, and POP3 servers are built-in for easy connection to Internet mail. Citadel is both robust and mature; it has been in production since 1987.

Release Notes: New features include a greatly improved XMPP (Jabber) service for better compatibility with more instant messenger clients, a completely new bulletin board (forum) view that is greatly improved in both performance and features, a brand new multiuser chat facility redesigned for better access through a Web browser, and many bugfixes and performance enhancements.
Release Notes: The following issues have been fixed: line-buffered I/O was handled incorrectly; when configuring a brand new Citadel installation for LDAP authentication, the LDAP configuration would be erased on the first server run and would need to be re-entered; issues with LDAP authentication on 64-bit systems; deleting the last unread message in a room would sometimes fail to mark the room as not containing new messages; a memory leak was associated with binary downloads; a small bug was in the Wiki room mode on 64-bit systems; a buffer size issue was in the text mode client.
Release Notes: Recurring events are now supported across the entire calendar system, as well as all-day events which span multiple days. The WebCit framework is now templatized. The mailbox summary view is now faster and more versatile. Support for virus scanning with ClamAV was integrated. Inline images are supported in message views. Interoperability with vCards generated by third-party address book software was improved. Fonts in WebCit are now relative sized, making the whole site look better on screens of all sizes. Performance improvements, user interface enhancements, and bugfixes were made.
Release Notes: When running mailing lists, the List-ID field is parsed and generated. Improved handling of the refcount_adjustments.dat file to prevent a rare condition where the file can't be renamed and therefore cannot be processed. The display of incoming instant messages through an IMAP client has been removed, because XMPP is now supported, so it would be redundant for most users.
Release Notes: This version adds an XMPP (Jabber) service. It also adds more security and granularity to the options provided by Citadel-hosted mailing lists.
