The 3rd Version of the Chat is a complete rewrite of the Old one. The design goals were speed, flexibility and performance. It now comes with a completely stand-alone Chatserver which will handle the Chatmessages. The Layout is even more flexible so that it is an ease, to integrate the Chatsystem in existing Websites.
Even though, the Message-Api is more flexible. Every chat command or message type has it's own function and can be easily changed or updated, and new commands can easily be integrated.
