The second alpha version of the email client Thunderbird 3, developed under the code name Shredder, has been released.

Some innovations:

• Go to the Gecko 1.9 platform, on the basis of which Firefox 3 is built;
• Discontinued support for Windows 95/98 / Me platforms;
• A new add-on manager, which can now be used to search, download, and select extensions that extend functionality. When you first open Tools> Add-ons, a list of recommended add-ons will be offered.
• The address book supports reading data from the Mac OS X system address book;
• A new means of sending notifications to developers in the event of a program crash;
• Each message can be opened in the new tab (by default it is not active, you need to enable it in the settings);
• More accurate search by message body, taking into account the language in which the letter is written (increasing search efficiency is one of the main areas of Thunderbird 3);
• An improvement in the JavaScript engine has resulted in an increase in overall performance and a reduction in memory consumption;
• On the Mac platform, the Thunderbird interface is now implemented using the Cocoa library;
• On the add-ons site, there are versions of DOM Inspector and Venkman debugger with Thunderbird 3 alpha1 support;
• The most anticipated innovation, the integration of the Lightning calendar-planner, will be implemented in future alpha versions.
