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.

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.
