底下幾點應該算是 0.4 的新功能
http://www.mozilla.org/projects/thunder ... admap.html
1 We will address our outstanding usability issues on Linux and OSX. This includes dispatching browser urls to the default browser on Linux. For OSX, better url dispatching between Thunderbird and Firebird and better management when the user closes all open Thunderbird windows.
2 A completed default theme based on Qute.
3 basic stand alone mail functionality (including proper interaction with the operating system for handling mail urls and requests)
4 All of the major functionality found in the Mozilla 1.6 beta mail client.
5 Ability to copy and paste images (including screen shots) from the clipboard to new mail messages on Windows.
6 Support for creating and using vCards.
7 An extension that enables address book synchronization with Palm Devices.
終於要支援 vCard 了
底下的則是 release notes 中的 new stuff

1) Fix for the doubling of messages some POP users were seeing in local folders. Thanks to the folks that helped test this out earlier today.
2) Fix for Bug #226325 --> Trailing stationary caret remnant left after backspace in mail compose editor
3) Changing the window configuration of the 3-pane ruins charset decoding for all subsequent messages loaded in that window. (Note: if a message is displayed while you change the config, then it may not render with the right charset but any future message or a reloading of that message works fine).
4) Encourage outgoing attachments to go out as binary to fix problems where binary attachments were getting encoded as quoted printable (Bug #226927)
5) Find in dialog works again for standalone message window
6) Security button can now be dragged into the customize toolbar dialog in mail compose.
7) Attachments with non-ASCII file names can now be saved correctly
8) Fix for regression installing themes and extensions that briefly appeared in RC1
如果有希望加入一些新功能的話,可以到下面這個討論串中去反應,這算是一個 wish list
