Eudora Releases
Eudora 8 is an email client that combines Mozilla's Thunderbird with code, features, and GUI elements from Qualcomm's Eudora.
Eudora 8.0b8 (5 Jan 2010)
The latest beta release of Eudora, version 8.0b8 (which includes the Penelope extension) is now available for download. Use the links below to download. Please see the README for information on how to submit bug reports and new feature requests.
Eudora 8.0b8 is based on the Thunderbird 3.0b4 source code, so add-ons that do not work with Thunderbird 3.0b4 likely will not work with this beta version.
Installation Note
Windows users upgrading from Penelope 0.1a19 have things pretty easy, but there's an extra step: uninstall Thunderbird, install Eudora 8, start Eudora, go into the Tools/Add-ons menu item and uninstall Penelope a19. Upon restarting Eudora the version of Penelope that came with it will automatically be reinstalled.
NOTE: many add-ons that worked with Eudora beta 1 won't work with beta 2 (or later, as of 2/8/08). It's a smart idea to do a full backup of all your mailboxes and preferences files before doing the upgrade, as "in place" upgrades may have problems.
