Changes:
This release fixed a bug with the navigation + action controls on the message view page, a browser redirect bug, and a max AJAX URL size bug. Several improvements were made to managing folder hierarchies. JavaScript files have been compressed and combined to reduce include overhead. Two new plugins are available, a "notices" plugin that plays a sound file or opens a window when a new message arrives, and "news", an RSS and ATOM news reader. The calendar plugin has major updates including event support for MySQL or PostgreSQL.
