Pontarius XMPP aims to be a secure and easy-to-use XMPP library for Haskell. We have just released a fourth alpha version with the following features: * Client-to-server Transport Layer Security and DIGEST-MD5 SASL Authentication * Concurrent, Flexible and Event-based API for XMPP Client Developers * Support for Info/Query, Presence and Message Stanzas * Interoperable XML Parsing (Using enumerator, xml-enumerator and xml-types) Please note that we are not recommending anyone to use Pontarius XMPP at this time as it’s still in an experimental stage and will have its API and data types modified. However, if you are interested to use Pontarius XMPP anyway, feel free to contact the Pontarius project and we will try to help you get started. You can also see the Example directory for a usage example. We are currently working on general improvements and having the library support all of RFC 3920: XMPP Core. The next version, 0.1 Alpha 5, is scheduled to be released on the 15th of June. Look at the Pontarius web site <http://www.pontarius.org/> and the Pontarius XMPP Hackage page <http://hackage.haskell.org/package/pontarius-xmpp/> for more information.
