Mozilla updated Thunderbird 2.0 to Beta 2, marking the latest step in the final release of the e-mail client.

Mozilla Thunderbird is an open-source, free and cross-platform e-mail client and news reader for most modern operating systems including, but not limited to Windows, Macintosh and Linux.

Thunderbird 2.0 Beta 2 includes a theme update for Mac OS X, improved previews in new mail alerts, setup for Google's Gmail and Apple's .Mac Web-based accounts, as well as any bug fixes generated from earlier reports.
Some of the updates of Thunderbird 2 Beta 2 are:

Message Tags: Create your own tags for organizing e-mail. Messages can be assigned any number of tags. Tags can be combined with saved searches and mail views to make it easier to organize email.

Visual Theme: Thunderbird 2's theme and user interface have been updated to improve usability.

Session History Navigation: Back and Forward buttons allow navigation through message history.

Improved New Mail Notification Alerts: New mail alerts include information such as the subject, sender and message text.

Saved Search Folder Performance: Search results for saved search folders are now cached, improving folder loading performance.

Updates to the extension system: The extension system has been updated to provide enhanced security and to allow easier localization of extensions.

New Windows installer: Based on Nullsoft Scriptable Install System, the new Windows installer resolves many long-standing issues.

Mozilla Thunderbird System Requirements can be found here.

The update, which will be distributed automatically to U.S. users of Beta 1, can be downloaded from Mozilla's Web site in 28 languages for Windows, Mac OS X, and Linux. The Mac OS X editions are Universal versions that work on both Intel- and PowerPC-based Macs.
