This change was necessary in order to bring you the advanced  user interface improvements in this latest version.

This release includes major enhancements to the Chat Windows user  interface including the following:
- Tabbed Chatting in 3 different styles. This allows you to  conserve screen real estate and have all your windows in one area.
- Styled Text Chats in 8 different styles. This allows you to see  your text chats displayed in multiple formats, including baloons like  iChat® or more formal styles. (This feature is only available  if you have Safari installed on your computer.)

In addition, we have added support for Rendezvous messaging, allowing  you to talk to any Fire or iChat user on your local network, without  the need for a central server.

Please note that this release is in English only. Localized  versions will be released just as soon as they are available.
